In 2022, U.N. Secretary-General António Guterres declared that the “lifeline of renewable energy can steer [the] world out of climate crisis.” In saying so, he echoed a popular and tantalizing idea: that, if we hurry, we can erase the climate emergency with widespread adoption of renewables in the form of solar panels, wind farms, electric vehicles and more.
But things aren’t that simple, and analysts increasingly question the naïve assumption that renewables are a silver bullet.
That’s partly because the rapid transition to a global energy and transport system powered by “clean” energy brings with it a host of new (and old) environmental problems. To begin with, stepping up solar, wind and EV production requires many more minerals and materials in the short term than do their already well-established fossil fuel counterparts, while also creating a major carbon footprint.
Also, the quicker we transition away from fossil fuel tech to renewable tech, the greater the quantity of materials needed up front, and the higher the immediate carbon and numerous other environmental costs. But this shift is now happening extremely rapidly, as companies, governments and consumers try to turn away from oil, coal and natural gas.
“Renewables are moving faster than national governments can set targets,” declared International Energy Agency executive director Fatih Birol. In its “Renewables 2024” report, the IEA estimates the world will add more than 5,500 gigawatts of renewable energy capacity between 2024 and 2030 — almost three times the increase between 2017 and 2023.
But this triumph hasn’t brought with it a simultaneous slashing in global emissions, as hoped. In fact, 2023 saw humanity’s biggest annual carbon releases ever, totaling 37.4 billion metric tons, which has led experts to ask: What’s going on?
The introduction of coal in 19th century England — an innovative, efficient, cheap new source of energy — made some wealthy, produced an onslaught of consumer products, and was a public health and environmental disaster. Contemplating the coal boom, economist William Stanley Jevons developed the Jevons paradox. Image via Wikimedia Commons (Public domain).
Jevons paradox meets limits to growth
Some analysts suggest the source of this baffling contradiction regarding record modern energy consumption can be found in the clamor by businesses and consumers for more, better, cheaper technological innovations, an idea summed up by a 160-year-old economic theory: the Jevons paradox.
Postulated by 19th-century English economist William Stanley Jevons, it states that, “in the long term, an increase in efficiency in resource use [via a new technology] will generate an increase in resource consumption rather than a decrease.” Put simply, the more efficient (and hence cheaper) energy is, the greater society’s overall production and economic growth will be — with that increased production then requiring still more energy consumption.
Writing in 1865, Jevons argued that the energy transition from horses to coal decreased the amount of work for any given task (along with the cost), which led to soaring resource consumption. For proof, he pointed to the coal-powered explosion in technological innovation and use occurring in the 19th century.
Applied to our current predicament, the Jevons paradox challenges and undermines tech prognosticators’ rosy forecasts for sustainable development.
Here’s a look at the paradox in action: The fastest-expanding renewable energy sector today is solar photovoltaics (PVs), expected to account for 80% of renewables growth in the coming years.
In many parts of the world, large solar power plants are being built, while companies and households rapidly add rooftop solar panels. At the head of the pack is China, with its astounding solar installation rate (216.9 GW in 2023).
But paradoxically, as China cranks out cheap solar panels for domestic use and export, it is also building six times more coal power plants every year than the rest of the world combined, though it still expects almost half its electricity generation to come from renewables, mainly solar, by 2028.
This astronomical growth at first seems like proof of the Jevons paradox at work, but there’s an unexpected twist: Why is China (and much of the rest of the world) still voraciously consuming outmoded, less-efficient fossil fuel tech, while also gobbling up renewables?
One reason is that coal and oil are seen as reliable, not subject to the same problems that renewables can face during periods of intense drought or violent weather — problems caused by the very climate change that renewables are intended to mitigate.
Another major reason is that fossil fuels continue being relatively cheap. That’s because they’re supported by vast government subsidies (totaling more than $1 trillion annually). So in a sense, we are experiencing a quadruple Jevons paradox, with oil, coal, natural gas and renewables acting like four cost-efficient horses, all racing to produce more cheap stuff for an exploding world consumer economy. But this growth comes with terrible environmental and social harm.
Exponential growth with a horrific cost
Back to the solar example: China is selling its cheap solar installations all over the globe, and by 2030 could be responsible for half the new capacity of renewables installed planetwide. But the environmental cost of satisfying that escalating demand is rippling out across the world.
It has spurred a huge mining boom. Desperate to satisfy fast-rising demand, companies and nations are mining in ever more inaccessible areas, which costs more in dollars, carbon emissions, biodiversity losses, land-use change, freshwater use, ocean acidification, plus land, water and air pollution. So, just as with fossil fuels, the rush to renewables contributes to the destabilizing of the nine planetary boundaries, of which six are already in the red zone, threatening civilization, humanity and life as we know it.
Mining, it must be remembered, is also still heavily dependent on fossil fuels, so it generates large quantities of greenhouse gases as it provides minerals for the renewables revolution. A January 2023 article in the MIT Technology Review predicts that the mining alone needed to support renewables will produce 29 billion metric tons of CO2 emissions between now and 2050.
Carbon is far from the only problem. Renewables also require a wide range of often difficult-to-get-at minerals, including nickel, graphite, copper, rare earths, lithium and cobalt. This means “paradoxically, extracting this large amount of raw materials [for renewables] will require the development of new mines with a larger overall environmental footprint,” says the MIT article.
There are other problems too. Every year 14,000 football fields of forests are cut down in Myanmar to create cheap charcoal for China’s smelting industries to process silicon, a key component of solar panels and of computers.
This rapid development in rural places also comes with harsh human costs: Mongabay has reported extensively on how Indigenous people, traditional communities and fragile but biodiverse ecosystems are paying the price for the world’s mineral demand in the transition to renewable energy.
There is strong evidence that the Uighur minority is being used as slave labor to build solar panels in China. There are also reports that workers are dying in Chinese factories in Indonesia that are producing nickel, a key metal for solar panels and batteries.

The search for solutions
“We really need to come up with solutions that get us the material that we need sustainably, and time is very short,” said Demetrios Papathanasiou, global director for energy and extractives at the World Bank.
One popularly touted solution argues that the impacts imposed by the rapid move to renewable energy can be greatly reduced with enhanced recycling. That argument goes this way: The minerals needed to make solar panels and build windfarms and electric vehicles only need to be sourced once. Unlike fossil fuels, renewables produce energy year after year. And the original materials used to make them can be recycled again and again.
But there are problems with this position.
First, while EV batteries, for example, may be relatively long lasting, they only provide the energy for new electric vehicles that still require steel, plastics, tires and much more to put people in the Global North and increasingly the Global South on the road. Those cars will wear out, with tires, electronics, plastics and batteries costly to recycle.
The solar energy industry says that “solar panels have an expected lifespan between 25-30 years,” and often much longer. But just because a product can last longer, does that mean people won’t clamor for newer, better ones?
In developed nations, for example, the speed at which technology is evolving mitigates against the use of panels for their full lifespan. A 2021 article in the Harvard Business Review found that, after 10 years or even sooner, consumers will likely dispose of their first solar panels, to install newer, more efficient ones. Again, the Jevons paradox rears its anti-utopian head.
Also, as solar proliferates in poorer nations, so too will the devices that solar can drive. As solar expands in the developing world, sales for cheap solar lanterns and small solar home electric systems are also expanding. An article in the journal Nature Energy calculates that in 2019 alone, more than 35 million solar products were sold, a huge rise from the 200,000 such products sold in 2010.
This expansion brings huge social benefits, as it means rural families can use their smartphones to study online at night, watch television, and access the market prices of their crops — all things people in the Global North take for granted.
But, as the article points out, many developing-world solar installations are poor quality and only last a few years: “Many, perhaps even the majority, of solar products sold in the Global South … only have working lives of a couple of years.” The problem is particularly acute in Africa. “Think of those solar panels that charge phones; a lot of them do not work, so people throw them away,” said Natalie Gwatirisa, founder of All For Climate Action, a Zimbabwean youth-led organization that strives to raise awareness on climate change. Gwatirisa calculates that, of the estimated 150 million solar products that have reached Africa since 2010, almost 75% have stopped working.
And as Americans familiar with designed obsolescence know, people will want replacements: That means more solar panels, cellphones, computers, TVs, and much more e-waste.
Another disturbing side to the solar boom is the unbridled growth of e-waste, much of it toxic. Gwatirisa cautions: “Africa should not just open its hand and receive [anything] from China because this is definitely going to lead to another landfill in Africa.”
The developed world also faces an e-waste glut. Solar panels require specialized labor to recycle and there is little financial incentive to do so. While panels contain small amounts of valuable minerals such as silver, they’re mostly made of glass, an extremely low-value material. While it costs $20-$30 to recycle a panel, it only costs $1-$2 to bury it in a landfill. And the PV industry itself admits that ‘the solar industry cannot claim to be a “clean” energy source if it leaves a trail of hazardous waste.’
Renewables are rapidly growing, producing a bigger share of global energy. But electricity demand is also soaring, as unforeseen new energy-guzzling innovations are introduced. For example, an artificial intelligence internet search is orders of magnitude more energy-intensive than a traditional Google search, and requires new power generation sources.

Solving the wrong problem
Ultimately, say some analysts, we may be trying to solve the wrong problem. Humanity is not experiencing an energy production problem, they say. Instead, we have an energy consumption problem. Thus, the key to reducing environmental harm is to radically reduce energy demand. But that can likely only be done through stationary — or, better still, decreased — consumption.
However, it’s hard to imagine modern consumers not rushing out to buy the next generation of consumer electronics including even smarter smartphones, which demand more and more energy and materials to operate (think global internet data centers). And it’s also hard to imagine industry not rushing to update its ever more innovative electronic product lines (think AI).
A decline in energy demand is far from happening. The U.S. government says it expects global energy consumption to increase by almost 50% by 2050, as compared with 2020. And much of that energy will be used to make new stuff, all of which increases resource demand and increases our likelihood of further overshooting already overshot planetary boundaries and crashing overstressed Earth systems.
One essential step toward sustainability is the circular economy, say renewable energy advocates. But, as with so much else, every year we somehow go in the opposite direction. Our current economic system is becoming more and more linear, built on a model of extracting more raw materials from nature, turning them into more innovative products, and then discarding it all as waste.
Currently, only 7.2% of used materials are cycled back into our economies after use. This puts an overwhelming burden on the environment and contributes to the climate, biodiversity and pollution crises.
If a circular economy could be developed by recycling all the materials used in renewables, it would significantly reduce the constant need to mine and source new ones. But, while efficient recycling will undoubtedly help, it also has limitations.
The 2023 planetary boundaries update shows six boundary safe limits transgressed: climate change (CO2 concentration and radiative forcing), biosphere integrity (genetic and functional), land-system change, freshwater change (blue water use and green water), biogeochemical flows (nitrogen and phosphorus), and novel entities pollution (including thousands of synthetic chemicals, heavy metals, radioactive materials, and more). The ocean acidification boundary is very near transgression. Only the atmospheric aerosol pollution and stratospheric ozone depletion boundaries are still well outside the red danger zone.

The future
Tom Murphy, a professor emeritus of the departments of physics and astronomy and astrophysics at the University of California, San Diego, became so concerned about the world’s future, he shifted his career focus to energy.
While initially a big promoter of renewables, having built his own solar panels back in 2008, he has recently turned skeptical. Panels “need constant replacement every two or three decades ad infinitum,” he told Mongabay. “Recycling is not a magic wand. It doesn’t pull you out of the need for mining. This is because recycling is not 100% efficient and never will be. In the laboratory maybe, but not in the real world. You’re going to have this continual bleed of materials out of the system.”
Yet another renewables problem is that sustainable energy is often siloed: It is nearly always talked about only in the context of reducing greenhouse gas emissions. Rarely are the total long-term supply chain costs to the environment and society calculated.
Reducing CO2 is clearly a vital goal, but not the only critical one, says Earth system scientist Johan Rockström, joint director of the Potsdam Institute for Climate Impact Research in Germany, and who (with an international team of scientists), developed the planetary boundaries framework.
It is undeniably important to reduce greenhouse emissions by half over the next seven years in order to reach net zero by 2050, he says. But this will be difficult to achieve, for it means “cutting emissions by 7.5% a year, which is an exponential decline.”
And even if we achieve such radical reductions, it will not solve the environmental crisis, warns Rockström. That’s because radical emission reductions only tackle the climate change boundary. A recent scientific paper, to which he contributed, warns that “six of the nine boundaries are transgressed, suggesting that Earth is now well outside of the safe operating space for humanity.”
Rockström in an exclusive interview told Mongabay that, at the same time as we vigorously combat global warming, “We also need to come back into the safe space for pollutants, nitrogen, phosphorus, land, biodiversity,” and more. This means that our efforts to repair the climate must also relieve stresses on these other boundaries, not destabilize them further.
Murphy says he believes this can’t be achieved. He says that modernity — the term he uses to delineate the period of human domination of the biosphere — cannot be made compatible with the protection of the biological world.
To make his point, he emphasizes an obvious flaw in renewables: they are not renewable. “I can’t see how we can [protect the biosphere] and retain a flow of nonrenewable finite resources, which is what our economic system requires.” He continues: “We are many orders of magnitude, 4 or 5 orders of magnitude, away from being at a sustainable scale. I like Rockström’s idea that we have boundaries, but I think his assessment of how far we have exceeded those boundaries is completely wrong.”
Murphy says he believes modernity has unleashed a sixth mass extinction, and it is too late to stop it. Modernity, he says, was unsustainable from the beginning: “Our brains can’t conceive of the degree of interconnectedness in the living world we’re part of. So the activities we started carrying out, even agriculture, don’t have a sustainable foundation. The minerals and materials we use are foreign to the living world and we dig them up and spew them out. They end up all over the place, even in our bodies at this point, [we now have] microplastics. This is hurting not just us, but the whole living world on which we depend.”
Like Murphy, Rockström says he is pessimistic about the level of action now seen globally, but he doesn’t think we should give up. “We have the responsibility to continue even if we have a headwind.” What is extremely frustrating, he says, is that today we have the answers: “We know what we need to do. That’s quite remarkable. Years back I could not have said that. We have solutions to scale down our use of coal, oil and gas. We know how to feed humanity from sustainable food systems, that largely bring us back into the [safe zone for] planetary boundaries, the safe space for nitrogen, phosphorous, freshwater, land and biodiversity.”
One key to making such radical change would be a dramatic, drastic, wholesale shift by governments away from offering trillions of dollars in “perverse subsidies” to environment-destroying fossil fuel and mining technologies, to pumping those subsidies into renewables and the circular economy.
Murphy says he doesn’t believe we should give up either. But he also says he doesn’t believe modernity can be made sustainable. “I suspect that the deteriorating web of life will create cascading failures that end up pulling the power cord to the destructive machine. Only then will some people accept that ecological ignorance — paired with technological capability — has dire consequences.”
But, he adds, this does not mean the human race is doomed.
“The modernity project does not define humanity. Humanity is much older. It’s too late for modernity to succeed but it’s not too late for humanity to succeed.” Here he turns to Indigenous cultures: “For hundreds of thousands of years, they survived and did quite well without causing the sixth mass extinction.”
“There isn’t a single Indigenous package,” he says. “Each is tuned to its [particular local] environment, and they vary a lot. But they have common elements: humility, only taking what you need from the environment, and the belief that we can learn a lot from our ‘our brothers and sisters,’ that is, the other animals and plants who have been around for much longer than us.”
Perhaps surprisingly, Murphy remains cheerful: “Most people are extremely depressed by what I say. I’m not. Not at all. I think it’s exciting to imagine what the future can be. You’re only depressed if you’re in love with modernity. If you’re not, it’s not devastating to imagine it disappearing.”

Editor’s note: You have nothing to fear from Artificial Intelligence (AI), at least that is what IT will tell you. It is called “alignment faking“, someone or thing purports to believe something they don’t because it could raise them in the esteem of potential “evaluators.” AI could save the world, but first, it will ruin the environment. AI has become an energy vampire. But communities are beginning to organize, pushing back against the unchecked expansion of data centres and the drain they incur on local resources. The longer the AI bubble continues the more it results in direct investment in physical infrastructure, and the more disastrous it will be for communities and the planet. AI is a product that people actively don’t want: including AI in marketing materials reduces the desire to purchase the product. AI is a proven loser.
AI is hailed as a game-changer. It has been hyped to solve everything from waste to climate change. But beneath its touted “transformative potential” lies a pressing concern: its environmental impact. The development, manufacture, maintenance, and disposal of AI technologies all have a large carbon footprint. Advertising algorithms are deliberately designed to increase consumption, which assuredly comes with a very significant ecological cost.
A record 62 million tonnes (Mt) of e-waste was produced in 2022, Up 82% from 2010; On track to rise another 32%, to 82 million tonnes, in 2030. Less than a quarter (22.3) per cent of the e-waste was documented as properly collected for recycling in 2022, with the remainder disposed of primarily in landfills. An undetermined amount of used electronics is shipped from the United States and other “developed” countries to “developing” countries that cannot reject imports or handle these materials appropriately.
Technology never exists in a vacuum, and the rise of cryptocurrency in the last two or three years shows that. While plenty of people were making extraordinary amounts of money from investing in bitcoin and its competitors, there was consternation about the impact those get-rich-quick speculators had on the environment.
Mining cryptocurrency was environmentally taxing. The core principle behind it was that you had to expend effort to get rich. To mint a bitcoin or another cryptocurrency, you had to first “mine” it. Your computer would be tasked with completing complicated equations that, if successfully done, could create a new entry on to the blockchain.
“Ultimately, the environmental impact of AI models like me will depend on how they are used,” Bard said. “If we use AI to solve environmental problems, then we can have a positive impact on the planet. However, if we use AI to create new environmental problems, then we will have a negative impact.”
Power-hungry AI is driving a surge in tech giant carbon emissions. Nobody knows what to do about it
Since the release of ChatGPT in November 2022, the world has seen an incredible surge in investment, development and use of artificial intelligence (AI) applications. According to one estimate, the amount of computational power used for AI is doubling roughly every 100 days.
The social and economic impacts of this boom have provoked reactions around the world. European regulators recently pushed Meta to pause plans to train AI models on users’ Facebook and Instagram data. The Bank of International Settlements, which coordinates the world’s central banks, has warned AI adoption may change the way inflation works.
The environmental impacts have so far received less attention. A single query to an AI-powered chatbot can use up to ten times as much energy as an old-fashioned Google search.
Broadly speaking, a generative AI system may use 33 times more energy to complete a task than it would take with traditional software. This enormous demand for energy translates into surges in carbon emissions and water use, and may place further stress on electricity grids already strained by climate change.
Energy
Most AI applications run on servers in data centres. In 2023, before the AI boom really kicked off, the International Energy Agency estimated data centres already accounted for 1–1.5% of global electricity use and around 1% of the world’s energy-related CO₂ emissions.
How is the rapid growth in AI use changing these figures? Recent environmental reporting by Microsoft, Meta and Google provides some insight.
Microsoft has significant investments in AI, with a large stake in ChatGPT-maker OpenAI as well as its own Copilot applications for Windows. Between 2020 and 2023, Microsoft’s disclosed annual emissions increased by around 40%, from the equivalent of 12.2 million tonnes of CO₂ to 17.1 million tonnes.
These figures include not only direct emissions but also indirect emissions, such as those caused by generating the electricity used to run data centres and those that result from the use of the company’s products. (These three categories of emissions are referred to as Scope 1, 2 and 3 emissions, respectively.)
Meta too is sinking huge resources into AI. In 2023, the company disclosed is Scope 3 emissions had increased by over 65% in just two years, from the equivalent of 5 million tonnes of CO₂ in 2020 to 8.4 million tonnes in 2022.
Google’s emissions were almost 50% higher in 2023 than in 2019. The tech giant’s 2024 environmental report notes that planned emissions reductions will be difficult “due to increasing energy demands from the greater intensity of AI compute”.
Water
Data centres generate a lot of heat, and consume large amounts of water to cool their servers. According to a 2021 study, data centres in the United States use about 7,100 litres of water for each megawatt-hour of energy they consume.
Google’s US data centres alone consumed an estimated 12.7 billion litres of fresh water in 2021.
In regions where climate change is increasing water stress, the water use of data centres is becoming a particular concern. The recent drought in California, where many tech companies are based, has led companies including Google, Amazon and Meta to start “water positive” initiatives.
These big tech firms have announced commitments to replenish more water than they consume by 2030. Their plans include projects such as designing ecologically resilient watershed landscapes and improving community water conservation to improve water security.
Climate risk
Where data centres are located in or near cities, they may also end up competing with people for resources in times of scarcity. Extreme heat events are one example.
Extreme heat translates to health impacts on local populations. A Lancet 2022 study found that even a 1°C increase in temperature is positively associated with increased mortality and morbidity.
On days of extreme heat, air conditioning can save lives. Data centres also like to keep cool, so their power use will spike with the temperature, raising the risk of blackouts and instability in electricity grids.
What’s next?
So what now? As we have seen, tech companies are increasingly aware of the issue. How is that translating into action?
Earlier this year we surveyed IT managers in Australia and New Zealand to ask what they thought about how AI applications are driving increased energy use. We found 72% are already adopting or piloting AI technologies.
More than two-thirds (68%) said they were concerned about increased energy consumption for AI needs. However, there is also significant uncertainty about the size of the increase.
Many IT managers also lack the necessary skills to adequately address these sustainability impacts, regardless of corporate sustainability commitments. Education and training for IT managers to understand and address the sustainability impacts of AI is urgently required.
Editor’s note: This year’s biannual Biodiversity COP was in Cali, Colombia, a country with the dubious distinction of topping the list of the number of environmental activists killed by a country in both 2022 (60) and 2023 (79) and will probably have that dubious honor this year with a continuingly rising number of (115) as of November 7th.
BOGOTÁ, Colombia — While music played in Bogotá’s streets and a sense of victory filled the air after a long protest, Ana Graciela received a new appointment on her calendar: the funeral of Carlos Andrés Ascué Tumbo.
Nicknamed Lobo (meaning “wolf” in Spanish), the esteemed Indigenous guardian and educational coordinator was killed Aug. 29, while his fellow guardians, the Kiwe Thegnas (or Indigenous Guard of Cauca) were protesting for better security in Cauca, Colombia. The region has increasingly become dangerous with incursions by illegal armed groups.
“The situation is tough. Women and children are being killed [almost] every day,” said Ana Graciela Tombé, coordinator of the Regional Indigenous Council of Cauca.
The Bogotá protest gathered more than 4,000 people, in what is known as a minga in the Andean tradition, against escalating violence in the region. After eight days, on Aug. 28, the Indigenous communities succeeded in getting President Gustavo Petro to sign a new decree, the Economic and Environmental Territorial Authority, which grants Indigenous territories greater autonomy to take judicial action against violence within their lands.
But the sentiment is bittersweet for the Indigenous Nasa and Misak activists in Ana’s homeland of Cauca, particularly in Pueblo Nuevo, a nationally recognized Indigenous territory (resguardo). They’ve lost a dear leader and role model, impassioned with protecting their ancestral territory, forests and youth from illegal armed groups.
Labeled the deadliest country for environmental defenders in 2023, Carlos, 30, was the 115th social leader killed in Colombia this year, according to the Development and Peace Institute, Indepaz.
Although the police investigation into his death is still underway, members of his community say they believe Carlos was the latest victim of armed groups and drug traffickers the Nasa people have struggled with for more than 40 years. Mongabay spoke with these members of the community, including Carlos’ family and friends, to gather more information on his life and killing that received little attention in the media.

Pueblo Nuevo is located in the central mountain range of the Andes in the Cauca department, which today has become a hub for drug trafficking and illicit plant cultivation. This is due to its proximity to drug trafficking routes to ship drugs to international markets, the absence of state presence and the remoteness of the mountains.
The loss of Carlos is both physical and spiritual, a close friend of Carlos, Naer Guegia Sekcue, told Monagaby. He left behind a void in the lives of his family which they are trying to fill with love, Naer said, and the community and guardians feel like they lost a part of their rebellion against armed groups.
The ‘Wolf’
Carlos was a member of the Indigenous Guard since his childhood. The children’s section of the Guard is called semillas, meaning “seeds,” for how they’ll fruit into the next generation of leaders protecting their territory.
He met his wife, Lina Daknis, through mutual friends at university. Lina, though not of Indigenous heritage, said she fell in love with his rebellious spirit, devotion and commitment to Indigenous rights. When Lina became pregnant, the couple decided to raise their daughter in the Indigenous reserve, Pueblo Nuevo.
For many in this Indigenous community, their lands and forests are far more than mere sustenance; they hold deep traditional and spiritual significance. Among the Nasa people, one significant ritual involves burying the umbilical cord under stones of a sacred fire (tulpa), symbolically tying them to their ancestral territories. According to the sources Mongabay spoke to, they consider that the lands and forests do not belong to them but are a loan from their children they are entrusted to protect.
Carlos was fully dedicated to this Indigenous Guard, Lina said.
Many days, he would get up in the middle of the night to patrol the territory. While facing well-equipped armed groups, the Indigenous Guard remained unarmed. They carry a ceremonial wooden baton, adorned with green and white strings as symbols of Indigenous identity. Carlos was particularly outspoken against illegal armed groups and coca cultivation. Faced with their invasions and deforestation on their territory, the Guard also took on the role of environmental defenders.
Coca cultivation, as done by armed groups to produce cocaine, not only impacts lives, but also the environment. The traditionally sacred crop is now tied to violence and degradation in the region.
According to Colombia’s Ministry of Justice, 48% of cultivation is concentrated in special management areas, including national parks, collective territories and forest reserves. Between 2022 and 2023, coca cultivation caused the deforestation of 11,829 hectares (29,200 acres) of forested land, according to the latest report from the United Nations Office on Drugs and Crime. This deforestation increased by 10% in 2023 and threatens biodiversity, placing more than 50 species at risk of extinction, the Ministry of Justice stated at the COP16 U.N. biodiversity conference.
In one instance, Carlos and the Guard destroyed coca plants, took photos and uploaded videos to social media. Shortly after, his family began receiving threats from anonymous people on social media, warning Carlos to be careful. Lina now said she believes these threats came from dissident groups profiting from coca cultivation.

In Cauca, several dissident groups are active, including Estado Central Mayor and the Dagoberto Ramos Front. These factions emerged following the 2016 peace agreement and consist of former FARC guerrillas who either rejected or abandoned the reintegration process. Law enforcement say their presence poses a persistent threat. Most recently, in May, a police station in Caldono was attacked, with local authorities suspecting the involvement of the Dagoberto Ramos Front.
Despite the danger, Carlos never stopped his work.
“I told him to leave the Guard, to go to another country, that they would kill him,” said his mother, Diana Tumbo. “But he didn’t leave us nor the Guard.”

The seeds of tomorrow
The road to the Carlos’ home is surrounded by peaceful landscapes: small villages, chicken restaurants and hand-built huts. But the graffiti on walls — “FARC EP” (Revolutionary Armed Forces of Colombia, People’s Army) and “ELN Presente” (National Liberation Army, Present) — are stark reminders of the violence. Despite the peace agreement signed between the FARC and the Colombian government in 2016, violence has resurged in Cauca.
Carlos saw the armed groups as a destructive force to youth by recruiting minors.
According to the annual report of the United Nations Commissioner for Human Rights, armed groups forcibly recruited at least 71 Indigenous children in 2023. Oveimar Tenorio, leader of the Indigenous Guard, said the armed groups no longer have the political ideology that once defined the FARC. Instead, their attacks on the Indigenous Guard are driven by profit and control of drug routes.
“We are an obstacle for them,” he told Mongabay.
The graffiti reads “FARC – EP,” which stands for “Revolutionary Armed Forces of Colombia – People’s Army.” An man sits on a bench in a square in Jamundí, Colombia. For decades, violence has been a part of daily life for Colombians. Image by Tony Kirby.
Carlos became an educational coordinator, supporting teachers with Indigenous knowledge programs and organized workshops for the schools in the Sath Tama Kiwe Indigenous Territory. He believed in educating youth not just with academic knowledge, but with a sense of pride in their Indigenous heritage and the need to protect their land, Naer said.
Carlos encouraged the young people not to feel ashamed of being Indigenous, but instead to learn from their own culture. He always carried a book by Manuel Quintín Lame, a historical Indigenous Nasa leader from Cauca who defended Indigenous autonomy in the early 20th century.
But Carlos’ approach was one of tenderness; he was always listening to his students and fighting for a better future for the youth. “He was convinced that real change started from the bottom up, through children and the youth,” Naer said.

Murder of the ‘Wolf’
His friends and family said Carlos’ actions made him a target.
On Aug. 29, 2024, Carlos went down to the village of Pescador, Caldono, to pick up his daughter from swimming lessons. It was a peaceful moment: mother, father and daughter having a family meal at a small restaurant. Afterward, Carlos went to refuel his motorbike at the gas station.
Suddenly, a stranger approached his wife in the restaurant, she said, asking, ‘Are you the woman who is with the man with the long hair? Something has happened, but I can’t say what.’
Carlos Andrés Ascué Tumbo of the Andes Mountains was shot in the head.
The Regional Indigenous Council of Cauca quickly blamed “criminal structures” linked to dissident FARC groups, particularly the Jaime Martínez and Dagoberto Ramos factions. However, the police investigation is ongoing, and the Fiscalía General de la Nación (Office of the Attorney General), which is overseeing the case, has not shared details with the public or Mongabay.
Mongabay approached Fiscalía General de la Nación and local authorities for comment but did not receive one by the time of publication.
Sept. 1, in a small village perched on a hillside, marked the date of Carlos’ funeral. Fellow members of the Indigenous Guard, wearing blue vests and carrying their batons, lined the dusty roads. They formed a solemn procession from Carlos’ house down to the cemetery with about 1,000 people walking around them through Pueblo Nuevo.
“We want to show our strength,” said Karen Julian, a university student in Cauca who didn’t know Carlos personally but felt compelled to attend his funeral. Along with others, she boarded a brightly painted chiva bus to Carlos’ home village, where he was laid to rest.

Children holding flowers led the way of the procession, followed by a cross and then the coffin. A woman rang the church bell and people chanted the slogan to resist armed groups: “Until when? Until forever!”
At the covered sports field at the center of the village, the funeral transformed into a political rally. “I will not allow another young person to die!” Carlos’ mother shouted to the audience. “I demand justice.” She spoke of her worries for her granddaughter, Carlos’ daughter, who stills had many plans with her father. She called on the community to stand united against the violence that has taken so many lives.
As Carlos’ coffin was lowered into the ground, the crowd began to swell, pressing in tightly with his 6-year-old daughter at the front row of the mass. All were watching as the coffin reached its final destination.
“Carlos’ death was not in vain,” Naer said. “The youth understand that they must follow his path. The younger generations will continue preserving the Indigenous traditions while defending our territories and rights.”

Editor’s note: Major plastic polluters win as the UN Treaty talks conclude without an agreement. Modern lifestyles and practices are intimately entwined with the use of plastics. Our phones, computers, food packaging, clothes, and even renewable energy technologies, such as wind turbine blades and the cables that connect them to the power grid, are all largely made from plastics. Plastics production requires fossil hydrocarbons and this connection continues to grow stronger daily. Powerful oil producers, both private companies and governments of oil-producing nations, were seen as the key impediment to a consensus deal. What will happen next? “Agree to a treaty among the willing even if that means leaving some countries that don’t want a strong treaty or concede to countries that will likely never join the treaty anyway, failing the planet in the process.”
“Plastic has been found everywhere on Earth — from deepest oceans to high mountains, in clouds and pole to pole. Microplastics have also been found in every place scientists look for them in the human body, from the brain to the testes, breast milk, and artery plaque. Microplastics pose health risks to humans and wildlife, researchers warn.” PFAS(perfluoroalkyl and polyfluoroalkyl substances) – “forever chemicals” contaminate biosolids(waste from sewage) used as fertilizer and pesticides, they also contain heavy metals and nitrates.
Today’s cheerleaders for increased birth rates are well aware of the silent cause of the ongoing rapid decline in male sperm counts. It’s the very industries these corporate managers run and governments regulate that is the blame. So you can be almost 100 percent sure that they are not going to address the real problem in order to achieve the goal of increasing human birth rates.
Laws must mandate companies to reduce their plastic footprint through production reduction, product redesign, or reuse systems — higher-priority strategies in the Zero Waste hierarchy,
Bottlenose dolphins leapt and torpedoed through the shallow turquoise waters off Florida’s Sarasota Bay. Then, a research team moved in, quickly corralling the small pod in a large net.
With the speed of a race car pit crew, veterinarians, biologists and their assistants examined the animals, checking vital signs while taking skin, blood and other samples. They held a petri dish over each dolphin’s blowhole until it exhaled, with an intensity similar to a human cough. Then, they rolled up the net and the dolphins swam off unharmed. A pod in Louisiana’s Barataria Bay was similarly tested.
Generations of dolphins have been part of this ongoing dolphin health study, which has been run by the Sarasota Dolphin Research Program since 1970. It tracks populations and individuals and also looks for health issues related to pollutants in the marine environment.
In the lab, scientists discovered that all 11 of the dolphins had breathed out microplastic fibers, shed from synthetic clothing, says Leslie B. Hart, associate professor at the College of Charleston and an author on this research. The fibers resembled those found in human lungs in previous studies, proving that dolphins, like us, are breathing plastic. In people, microplastic has been linked to poor lung function and possible lung disease.
The dolphin studies are part of a larger quest to understand how plastic pollution is impacting the world’s wildlife. While thousands of human studies have demonstrated damage from tiny plastic particles entering both cells and organs throughout the body, little is known about animal impacts because long-term field studies are difficult and costly. “We’re really just starting to skim the surface,” Hart says.
Beyond the threat plastics pose to individual animals and species, other researchers have detected broader, global harm, a new report warns. Plastic pollution is transforming Earth systems needed to support life, worsening climate change, increasing biodiversity loss, making oceans more acidic and more.
The plastics crisis is escalating rapidly: Each year, petrochemical manufacturers make more than 500 million tons of plastics –– but the world recycles just 9%. The rest is burned, landfilled or ends up in rivers, rainwater, the air, soil or the sea. Today, the planet is awash in plastic. “It’s everywhere. It’s pervasive and it’s persistent,” says Andrew Wargo, who focuses on ecosystem health at the Virginia Institute of Marine Science.
Since the 1930s the polymers industry has completely altered daily life: Plastics are in our homes, cars, clothes, furniture, and electronics, as well as our single-use throwaway water bottles, food packaging and takeout containers.
A critically important fifth round of negotiations begins Nov. 25 when delegates hope to hammer out final treaty language for ratification by U.N. member states.
Meanwhile, the natural world is in great danger, threatened by a biodiversity crisis, a climate crisis and serious degradations of planetary systems. Researchers are now scrambling to understand the growing threat plastics pose to the health of all living organisms.
Plastics conquer the world
Bakelite, the first synthetic plastic product ever made, came on the market in 1907. By the 1950s, production ramped up, changing the course of history and revolutionizing modern life. Plastics facilitated innumerable human innovations — and spawned a throwaway culture. Add in poorly regulated petrochemical manufacturing processes and industrial fishing’s plastic gear, and global plastic pollution stats soared.
Plastic debris was first noticed in the oceans in the early 1960s. For a long time, ecologists’ main wildlife concerns focused on the threat to sea turtles and other marine creatures that ate plastic bags or became tangled in plastic fishing nets. Now, everything from zooplankton to sharks and seabirds eat it and are exposed to it.
Hart emphasizes the problem’s global scope: “Plastic pollution has been found on every continent and in every ocean, in people, terrestrial wildlife and marine wildlife.” It contaminates creatures across the tree of life and concentrates up the food chain, threatening

Insidious plastic harm to health
It’s well known that animals regularly mistake plastic debris for food. Shearwaters and other seabirds, for example, can choke and starve when plastic pieces block their digestive tracts or pierce internal organs. At least 1,565 species are known to ingest plastic. For decades, scientists have noted dead animals ensnared in plastic nets, fishing gear or six-pack rings.
But those big pieces of petrochemical plastic (along with their chemical additives) don’t decompose; they degrade into ever-smaller pieces, getting smaller and smaller. Eventually, they break down into microplastics, tiny particles no bigger than a grain of sand, or become nanoparticles, visible only under a high-powered microscope. These microplastics can leach toxic chemicals. Of the more than 13,000 chemicals currently used in plastics, at least 3,200 have one or more “hazardous properties of concern,” according to a U.N. report.
Most of what we know today about the health impacts of plastics and their chemical additives is based on human medical research, which may offer clues to what happens to animals; that’s unlike most health research, which is done on animals and extrapolated to people.
We know from human medical research that microplastics can damage cells and organs and alter hormones that influence their function. Plastic particles have crossed the blood-brain barrier. They have lodged in human bone marrow, testicles, the liver, kidneys and essentially every other part of the body. They enter the placenta, blood and breast milk. Exposure may affect behavior and lower immunity.
And what plastics do to us, they likely do to animals. The phthalates found in Florida dolphins, for example, along with phenols, parabens and per- and polyfluoroalkyls, are just a fraction of the many endocrine disruptors released by plastics and their chemical additives that can alter hormone levels and derail body functions. Exposure may affect behavior and lower immunity.
Plastic does not disappear: It breaks down into smaller and smaller pieces that settle in soil and float in the air and water. Microplastic can easily penetrate living organisms, their cells, and even cross the blood-brain barrier. Image by European Commission (Lukasz Kobus) via Wikimedia Commons (CC BY 4.0).
Doctors have confirmed links between plastic and human disease and disability. “They cause premature birth, low birth weight, and stillbirth as well as leukemia, lymphoma, brain cancer, liver cancer, heart disease and stroke,” Phil Landrigan, a pediatrician and environmental health expert stated in a press conference earlier this year.
In the wild, animals are now exposed daily to microplastics, eating and breathing them, while many freshwater and marine species swim in a plastic soup. But little is known about the long-term impacts of chronic exposure or what microplastics do within animal tissues, with even less understood about what happens when microplastics shrink to nano size and easily enter cells.
In lab experiments, microplastics in the lungs of pregnant rats easily passed to their fetuses’ brains, hearts and other organs. In adult mice, plastic nanoparticles crossed the blood-brain barrier, triggering swift changes that resembled dementia. In a wild animal, cognitive decline can quickly prove fatal, making it difficult to find food, avoid predators, mate or raise young.
In the lab, fish were more susceptible to a common virus after a one-month exposure to microplastic. They then shed more virus (a fish public health problem) and died in high numbers. Surprisingly, “there’s a lot of similarities between fish and humans, so that we have a lot of the same immune pathways,” explains Wargo, an author on this study. However, the reaction depended on the type of plastic. Nylon fibers had the biggest effect; most nylon sheds from synthetic clothing.
Nearly all Laysan albatross (Phoebastria immutabilis) carcasses found on Midway Atoll contain marine plastic debris. Experts estimate that albatrosses feed their chicks approximately 10,000 pounds of marine debris annually on Midway, enough plastic to fill about 100 curbside trash cans.

One challenge to researching health impacts, Wargo explains, is that “plastics oftentimes are lumped into one category, but they’re [all] very different: their structure, chemical composition, their shape and size,” creating thousands of variations. These factors influence how toxic they are, he says, which likely varies between individual animals and different species. Investigation is further complicated and obstructed by petrochemical companies that zealously guard their proprietary polymer product formulas.
The ubiquity of plastics and their global presence means that polymers likely have many undetected and unstudied wildlife health impacts. Some impacts could be masked by other environmental stressors, and untangling and analyzing the particulars will likely take decades.
What we do know is that the poor health, decline or disappearance of a single species within a natural community ripples outward, affecting others, and damaging interconnected ecological systems that have evolved in synchrony over millennia. Here’s just one speculative concern: We know microplastics can bioaccumulate, so apex predators, which balance ecosystems by keeping prey species in check, may be at high risk because they consume and build up large concentrations of microplastics and additive chemicals in their organs.
Plastics harm wildlife –– and humans –– in additional ways: by polluting the air and contributing to climate extremes. Currently, about 19% of plastic waste is incinerated, releasing potentially harmful chemical aerosols into the air. In addition, plastic production sends 232 million metric tons of greenhouse gases into the atmosphere yearly. Then there’s the pollution and carbon released from fracking and drilling operations to source the oil and gas to make these products.
Lastly, the microplastics animals and humans ingest are “Trojan horses.” These tiny particles absorb and carry a wide range of pollutants and bacteria, which then can enter and lodge within our bodies.
Single-use plastic bottles and other throwaway plastic packaging are a major cause of plastic pollution, with many activists and nations calling for a ban. While plastic bottles can be recycled, they frequently aren’t. Also, plastics degrade every time they’re recycled and are usually recycled only once or twice.

Stanching ‘a global-scale deluge of plastic waste’
Climate change and the plastics crisis spring from the same source: The world’s seven largest plastic manufacturers are fossil fuel companies. The U.S. produces the most plastic waste of any country, more than the entire EU combined: 42 million metric tons annually, or 287 pounds per person, according to a 2022 congressional report. It noted that “The success of the 20th-century miracle invention of plastics has also produced a global-scale deluge of plastic waste seemingly everywhere we look.”
Consumers can take small actions to protect themselves and limit plastic pollution by avoiding single-use plastics and carrying reusable bags and stainless-steel water bottles. Disposable fast-food packaging makes up almost half of plastic garbage in the ocean, so cutting back on takeout and bottled water could help.
But realistically addressing the planet’s plastics emergency requires a global paradigm shift that reframes the discussion. Many nations still think of plastics as a waste management issue, but responsibility needs to fall on the shoulders of regulators — and the producers, specifically fossil fuel companies and petrochemical manufacturers.
An international consortium of scientists has stressed the need for “urgent action” in the run-up to this month’s United Nations plastics treaty negotiations, the fifth and hopefully final summit intended to establish international regulations.
The U.S. had been among the largest, most influential dissenters in efforts to limit global plastics production and identify hazardous chemicals used in plastics. But in August 2024, prior to the U.S. presidential election, the Biden administration publicly announced it had toughened its position, supporting production limits, but submitted no position paper. Then, this week it returned to its earlier stance that would protect the plastics industry from production caps.
The plastics treaty summit in Busan, South Korea, beginning Nov. 25 and ending Dec. 1, aims to finalize treaty language that will then need to be ratified by the world’s nations. Regardless of the summit’s outcome, scientists continue to uncover new evidence of plastic’s dangers to humans, animals and the planet, raising the alarm and need for action.

Editor’s note: “Our heating of the Earth through carbon dioxide and other greenhouse gas pollution, is closely connected to our excessive energy consumption. And with many of the ways we use that energy, we’re also producing another less widely discussed pollutant: industrial noise. Like greenhouse-gas pollution, noise pollution is degrading our world—and it’s not just affecting our bodily and mental health but also the health of ecosystems on which we depend utterly.”
“Our study presents a strong, albeit selfish, argument for protecting natural soundscapes.”
Wind turbines in coastal waters, along with the noise from construction and surveys, have led to concerns about their impact on marine life. “In particular, cetaceans such as whales and dolphins are likely to be sensitive to the noises and increased marine traffic brought by these turbines.” These marine mammals’ survival depends on the technology of bounce to hear noise thousands of miles away through echolocation.
There are growing concerns regarding artificial sounds produced in waters that could impact marine life negatively. The effects of ocean noise produced by sonar, oil and gas exploration, offshore wind, and ship traffic could alter the behavior of mammals and cause hearing loss or potentially even death. “The latest discovery in this field could provide substantial ground for alterations in the Marine Mammal Protection Act that dictated the kind of noise-inducing activities that can be carried out in the waters. This new conclusion could hinder the scale of the activities or even get certain types of equipment banned from use at sites.”
‘It’s nonstop’: how noise pollution threatens the return of Norway’s whales.
It started as a simple spreadsheet that documented locations where researchers were recording sound to monitor biodiversity. Three years on, the Worldwide Soundscapes project is a global database on when, how and where passive acoustic monitoring is being deployed around the world to study terrestrial as well as aquatic ecosystems.
“This is a project that is now becoming too big to be handled by only one person,” Kevin Darras, currently senior researcher at France’s National Research Institute for Agriculture, Food and Environment (INRAE), who conceived the project, told Mongabay in a video interview.
Darras started the project when he was a postdoctoral researcher at Westlake University in China. The idea struck when he was waiting for updates on another project he was working on at the time. With the project, Darras said he was attempting to fill a void that often led to duplication of efforts in the research community that uses passive acoustic monitoring — audio recorders left out in the wild — to study biodiversity around the world. “There was a scientific gap in the sense that we didn’t know where and when we were sampling sound for monitoring biodiversity,” he said.
Passive acoustic monitoring has long been used to listen in on insects, birds and other animals in ecosystems around the world. It’s aided scientists to detect elusive species in a noninvasive manner. For example, a team in Australia used acoustic recorders and artificial intelligence to track down the breeding hollows of pink cockatoos (Lophochroa leadbeateri leadbeateri) in a remote region. The method has also helped researchers get insights into the behavioral and communications patterns of animals.
Despite advances in recent years with more sophisticated recorders and automated data analysis, Darras said researchers still haven’t “achieved standardization in terms of deployment or analysis.” Darras said he hoped to use the Worldwide Soundscapes project to help build a supportive network that could potentially work toward harmonizing approaches to passive acoustic monitoring.
“We hope people will look at the data and see what is already done to avoid duplication,” he said. “They might also probably find a colleague’s work and wonder, ‘Oh, why is this gap not filled? Maybe I can do something there.’”
Kevin Darras spoke with Mongabay’s Abhishyant Kidangoor on why he started the Worldwide Soundscapes project, how he envisions it growing into a global network, and the potential of ecoacoustics in biodiversity monitoring. The following interview has been lightly edited for length and clarity.
Mongabay: To start with, how would you describe the Worldwide Soundscapes project to someone who knows nothing about it?
Kevin Darras: In a fairly simple way, I would describe it as a simple inventory of what has been done globally, whether it’s aquatic or terrestrial, in terms of acoustic recording for monitoring biodiversity. Our first goal was to compile something like a phonebook for connecting people who are usually separated by the realms that we study. What I mean by that is we don’t communicate as much among ourselves. For example, marine scientists usually don’t talk much with terrestrial scientists. We have now succeeded in connecting and bringing people together. However, very early on, we realized that we could do more than that, and that we could put our metadata together to get a comprehensive picture of what is going on worldwide in terms of acoustic sampling.
Mongabay: What gaps were you trying to fill with this project?
Kevin Darras: There was a scientific gap in the sense that we didn’t know where and when we were sampling sound for monitoring biodiversity. There was also this gap in the community that made us not so well aware of the developments in other fields. There have been a lot of parallel efforts in different realms when, in reality, the same solutions might already exist in other communities. Our aim is to first make everyone aware of what is out there and ideally, one day, to harmonize our approaches and to benefit from each other’s experience.
Mongabay: Could you give me an example of how acoustic research efforts were duplicated in the past?
Kevin Darras: There are lots of examples when it comes to sound recording, calibration and the deployment of equipment. Because deployment in the deep sea is very much more troublesome and costly, our marine scientists go to great lengths to calibrate their equipment to make every deployment really worth it and to get data that are standardized. As a result, they are able to usually measure noise levels, for instance. Whereas those of us in the terrestrial realm have access to such cheap recorders that setting them up is almost too easy. The consequence is that, generally, we have very large study designs where we deploy hundreds of sensors and recorders and end up with a massive data set that, unfortunately, isn’t very well calibrated. We would only have relative sound levels and won’t be able to really measure noise levels.
On the other hand, I think the community that does terrestrial monitoring has made some great strides with respect to the use of artificial intelligence for identifying sound. By now, we have achieved a pretty consistent approach to bird identification with AI. This is something that could benefit people working in the aquatic realm who often have custom-made analysis procedures.
Mongabay: What was the spark to get started with this?
Kevin Darras: It started three years ago. I was actually busy with another project where I was working on an embedded vision camera. Between the development rounds, we had some time where we were waiting for the next prototype. Rather than just sit and wait, I told my supervisor that I wanted to start another project while waiting for updates. This is when I started contacting people from my close network to find out where they’ve been recording. It started with filling an online spreadsheet, which has grown since then. By now, I believe, a good portion of the community that uses passive acoustic monitoring knows about the project.
Mongabay: Could you tell me how it works currently?
Kevin Darras: The way it currently works is that people find out from their colleagues. Or we actively search for them. Then we send them all the basic information about the project. We ask them to fill in the data in a Google spreadsheet, but we are slowly transitioning to enter everything directly on a website. In the very beginning of the project, we didn’t have the capability, and we needed a really easy and effective way of adding people’s data. A Google spreadsheet was a fairly good idea then. Then we validate the data to see if things make sense. We cross-validate them with our collaborators after showing them the timelines and the maps that represent when and where their recordings have been made. In the end, there is a map which shows where all sounds have been recorded. For each collection, you can also view when exactly the recordings have been made.
Mongabay: Could you give me a sense of the kind of data in the database?
Kevin Darras: If you were a potential contributor, you would have to first provide some general information. Who are the people involved? Are the data externally stored recordings or links? Then we would get to the level of the sampling sites. We require everyone to provide coordinates and also to specify what were the exact ecosystems they were sampling sounds in. That’s the spatial information.
For the temporal information, we ask people to specify when their deployments started and when it stopped, with details on date and time. We also ask for whether they are scheduled recordings with predefined temporal intervals, like daily or weekly, or duty-cycled recordings, meaning one minute or every five minutes, or if they are continuous recordings.
We also request audio parameters like the sampling frequency, high-pass filters, number of channels, the recorders and microphones that they used. Lastly, we ask them to specify whether their deployments were targeting particular [wildlife], which is not always the case. Sometimes people just record soundscapes with a very holistic view.
Mongabay: How do you hope this database will help the community that uses passive acoustic monitoring?
Kevin Darras: We hope people will look at the data and see what is already done to avoid duplication. They might also probably find a colleague’s work and wonder, “Oh, why is this gap not filled? Maybe I can do something there.”
Mongabay: What surprised you the most?
Kevin Darras: It’s probably how big some of these studies were. I was amazed by the sampling effort that, for instance, some Canadian groups did over hundreds of sites over many years.
Also surprising for me was that there were some really gaping holes in our coverage in countries where I would have thought that the means existed for conducting eco-acoustic studies. Many North African countries don’t seem to be doing passive acoustic monitoring. We’ve just had our first collaborator from Turkey. Central Asia is poorly covered. This is for terrestrial monitoring.
For marine monitoring, I was actually surprised to see that the coverage was rather homogeneous. It’s sparse because it’s more difficult to deploy things underwater, but it was globally well distributed. I was surprised to see how many polar deployments there were, for instance, under very challenging conditions. Those are very expensive missions.
Mongabay: What was the biggest challenge in doing this?
Kevin Darras: It’s making everyone happy [laughs].
We had to be fairly flexible with what we expected from people and our criteria. Basically, we decided to trust our collaborators and it worked pretty well. Some people would struggle to provide basic metadata and would have to organize themselves and their data before being able to provide it. Others would be like, “Sure, I can send this to you in five minutes,” and then you get a huge data sheet.
Mongabay: Now that you have a fair idea of how acoustic monitoring is being used around the world, how do you think it is faring when it comes to biodiversity monitoring?
Kevin Darras: I think that the point is too often made that passive acoustic monitoring is something promising and something that has just started. Passive acoustic monitoring has been mature for some time already. It’s true that we haven’t achieved standardization or impact in terms of deployment or analysis, but we are, when using this technology, fairly efficient and effective for gathering rather comprehensive data about biodiversity. I don’t think we need to convince anyone anymore that this is useful and that this is a valid sampling method.
But I have a feeling that this message has not yet reached everyone who’s not using passive acoustic monitoring. It’s rather surprising for me to see that it hasn’t achieved the same level of standardization as what has been done with environmental DNA, when I think that the potential is just as big. Of course, it’s not comparable one to one, but it’s a sampling method that will enable us to have some great global insights.
Mongabay: How do you envision the future of Worldwide Soundscapes?
Kevin Darras: This is a project that is now becoming too big to be handled by only one person. I am soon going to have discussions with the people who want to be involved more deeply so that we have a team that is managing the Worldwide Soundscapes project.
We are going to continue integrating more and more data. We are also looking into automated ways to continue to grow the database from which we can then analyze data to answer macro-ecological questions. As of now, we have only shown the potential of the database. We still need to ask those big ecological questions and show that we can answer them with the database. We would also really like to reach those people in regions where passive acoustic monitoring has not been done yet.
One of the things we’re going to try to develop is something that we’ve tried already on a small scale within our network. To give you an example, I had a North African colleague who wanted to do passive acoustic monitoring in the Sahara and he obtained some recorders from a Polish colleague in the same network. It wasn’t even a loan. They were gifted to him and this enabled him to plug a gap in our coverage. I am hoping that we can develop the network in that sense, where we can loan equipment and provide knowledge for capacity building. It sounds ambitious, but sometimes it’s as simple as sending a postal parcel. I hope it will help expand the use of passive acoustic monitoring.
JAKARTA — German chemical giant BASF and French miner Eramet have pulled out of a multibillion-dollar “green energy” project in Indonesia because of its impact on one of the last Indigenous tribes on Earth living in voluntary isolation.
In an announcement on June 24, both companies said they had scrapped plans to invest up to $2.6 billion in the project on the island of Halmahera in Indonesia’s eastern province of North Maluku. The Sonic Bay project would have seen the construction of a refinery producing about 67,000 metric tons of nickel and 7,500 metric tons of cobalt a year. These metals, crucial ingredients in electric vehicle batteries, would have come from the nearby Weda Bay Nickel mine, the world’s largest nickel mine, in which Eramet holds a minority stake.
In its announcement, BASF said it would “stop all ongoing evaluation and negotiation activities for the project in Weda Bay.”
The decision came after a sustained campaign by activists voicing concerns that the Sonic Bay refinery, which is essentially an extension of the Weda Bay Nickel project, would increase the risk of Indigenous peoples in the area losing their lands. Weda Bay Nickel’s concession overlaps with rainforest that’s home to hundreds of members of the Forest Tobelo people, according to U.K.-based Indigenous rights NGO Survival International, which has lobbied both BASF and the German authorities to drop out of the project.

‘The people who live in the forest’
The Forest Tobelo tribe are among the last Indigenous groups still living in voluntary isolation from the rest of world. They are believed to number between 300 and 500 hunter-gatherer nomadic peoples whose way of life is so intricately tied to the environment that they call themselves O’Hongana Manyawa — the people who live in the forest.
Because the Forest Tobelo people avoid contact with outsiders, it’s unlikely they could ever be reasonably consulted about any projects in their area, or give their free, prior and informed consent (FPIC) for the use of their customary lands. Some tribe members have emerged from their isolation to report losing their forests to the mining concession.
As such, any investment in the Sonic Bay project would likely contribute to the ongoing destruction of the Forest Tobelo people’s forests, Survival International said.
This could be a reason why BASF and Eramet pulled out of the project, said Pius Ginting, coordinator of the Indonesian NGO Action for Ecology and Emancipation of the People (AEER). BASF’s stated reason is that the supply of battery-grade nickel in the market has eased, and that it therefore doesn’t need to invest so heavily to secure supplies.
What it doesn’t mention, however, is that its home government, Germany, is legally obligated to protect, respect and implement the rights of Indigenous and tribal peoples and improve their living and working conditions in the countries where they live. That’s because Germany in 2021 ratified the International Labour Organization’s Indigenous and Tribal Populations Convention.
That would therefore make any German company’s involvement in a project like Sonic Bay that threatens Indigenous peoples a violation of the convention, Pius said.
He also pointed out that WBN had scored poorly in a routine annual assessment of environmental parameters by Indonesia’s Ministry of Environment and Forestry. Known as the PROPER assessment, it assigns a color code to rate companies’ performance, ranging from gold to green to blue to red to black; a gold or green grade means a company exceeds legal requirements.
In 2022, Weda Bay Nickel received a red grade, meaning it failed to operate in accordance with existing environmental and social regulations.
“Even if [BASF and Eramet] said the main reason [for their withdrawal] is because of the market and the economy, we see that environmental risks are of course being considered as well due to WBN’s bad PROPER score,” Pius said.
He added their abandonment of the project should be a wake-up call for the rest of the battery metals industry and the Indonesian government to improve the environmental, social and governance (ESG) performance of the industry.

‘No-go zone’ to protect Indigenous tribe
Despite this development, WBN’s mining operation looks set to continue as the government pushes for Indonesia to become a powerhouse in the production of battery metals. This means the Forest Tobelo people will continue to be at risk of losing their forests, Survival International said.
The campaign group recently posted a video showing an uncontacted Forest Tobelo family approaching workers at a mining camp. According to Survival International, the family was asking for food after their rainforest was destroyed. It said similar scenes can be prevented by establishing a no-go zone, where no mining or other activities can take place.
Much of the nickel mined at Weda Bay goes to Chinese EV makers; the mine’s majority stakeholder is Tsingshan Holding Group, the world’s biggest nickel producer. Tesla, which doesn’t currently source nickel from Weda Bay but has signed agreements worth billions of dollars with Indonesian nickel and cobalt suppliers, said in its 2023 impact report that it was “exploring the need for a no-go zone” to protect uncontacted Indigenous peoples.
In a meeting with Survival International representatives, senior Indonesian politician Tamsil Linrung also voiced his support for the protection of the Forest Tobelo people through the establishment of a no-go zone.
“We will try to make that region a no-go zone. If not in the near future, perhaps after the next president is sworn into office [in October 2024],” he said.

Respite — for now
For now, the news that BASF and Eramet are dropping out of the refinery project provides some respite for the Forest Tobelo people, said Survival International director Caroline Pearce.
“BASF’s withdrawal means that they, at least, will not be complicit in the Hongana Manyawa’s destruction. But Eramet, and other companies, are still ripping up the rainforest and the uncontacted Hongana Manyawa simply won’t survive without it. They must stop now, for good, before it’s too late,” she said.
But another top official, Investment Minister Bahlil Lahadalia — who faces allegations of self-dealing and corruption in the revocation and reissuance of mining permits — said negotiations are still underway to get BASF and Eramet to invest in the refinery. He attributed their withdrawal to a decline in EV sales in Europe as a result of weakening purchasing power, but said this would only be temporary.
“[The project] is still pending,” he said as quoted by Indonesian news website Tempo.co. “We’re still negotiating.”
