Editor’s note: The International Day for Biodiversity was celebrated on May 22, which commemorates the adoption of the Convention on Biological Diversity, a global treaty. What lessons have we learned from undoing past harms and conserving biodiversity for our planet’s future?
Global efforts to restore forests are gathering pace, driven by promises of combating climate change, conserving biodiversity and improving livelihoods. Yet a recent review published in Nature Reviews Biodiversity warns that the biodiversity gains from these initiatives are often overstated — and sometimes absent altogether.
Restoration has typically prioritized utilitarian goals such as timber production, carbon sequestration or erosion control. This bias is reflected in the widespread use of monoculture plantations or low-diversity agroforests. Nearly half the forest commitments in the Bonn Challenge to restore degraded and deforested landscapes consist of commercial plantations of exotic species, a trend that risks undermining biodiversity rather than enhancing it.
Scientific evidence shows that restoring biodiversity requires more than planting trees. Methods like natural regeneration — allowing forests to recover on their own — can often yield superior biodiversity outcomes, though they face social and economic barriers. By contrast, planting a few fast-growing species may sequester carbon quickly but offers little for threatened plants and animals.
Biodiversity recovery is influenced by many factors: the intensity of prior land use, the surrounding landscape and the species chosen for restoration. Recovery is slow, often measured in decades, and tends to lag for rare and specialist species. Alarmingly, most projects stop monitoring after just a few years, long before ecosystems stabilize.
Scientists underline that while proforestation, reforestation and forest rewilding can contribute to curbing climate change and biodiversity loss, they have their limits and must be combined with deep carbon emissions cuts and conservation of existing forests and wilderness.
Edward Faison, an ecologist at the Highstead Foundation, stood quietly in a patch of forest that stretched for miles in all directions. Above him, the needles from white pine trees swayed — common in the Adirondack Forest Preserve in northern New York state. He stepped past downed wood and big, broken snags, observing how the forest functioned with minimal interference.
“These forests have been essentially unmanaged for over 125 years. To see them continue to thrive and accumulate carbon, recover from natural disturbances and develop complexity without our help reveal just how resilient these systems are,” Faison says.
Protected from logging in 1894 by an act of the New York Legislature, the Adirondack Forest Preserve (AFP) is a model of natural forest growth, or letting forests simply “get on with it.” The largest trees, white pines (Pinus strobus), are more than a century old and stretch more than 150 feet tall and are 4-5 feet in diameter.
The AFP, the largest wilderness preserve in the eastern United States, is a prime example of what researchers have come to call “proforestation.” Coined in 2019 by Tufts University professor William Moomaw and Trinity College professor of applied science Susan Masino, the term proforestation describes the process of allowing existing forests to continue growing without human interference until they achieve their full ecological potential for carbon sequestration and biological diversity.
Proforestation is considered a natural climate solution, i.e., a strategy to steward the Earth’s vegetation to increase the removal of carbon dioxide (CO2) from the atmosphere. According to Faison, a forest naturally develops greater complexity over time, with a diversity of tree sizes and heights as well as large standing dead trees and downed logs. This complexity provides habitat for various animals, plants and fungi, which make the forest more resilient to disturbances associated with climate change.
Proforestation is distinct from reforestation, which can involve planting new trees in deforested areas to restore them (or allowing deforested areas to naturally regenerate). It is also different from afforestation, which is the process of planting new forests in previously unforested areas. Proforestation’s merit lies in inaction: simply leaving old forests undisturbed, allowing for continuous growth to maximize carbon accumulation over time. As forests mature and trees grow larger, they sequester greater amounts of carbon.
“The largest 1% diameter trees in a mature multiage forest hold half the carbon,” according to Moomaw. “It’s the existing forests that we have that are doing the work.” Existing forests remove almost 30% of CO2 from the atmosphere that humans put in every year from burning fossil fuels.
Older is better
In Mohawk Trail State Forest in Massachusetts, Moomaw studied the tallest grove of white pine trees in New England, aged between 150 and 200 years, observing how the trees grew. When comparing them with younger trees of the same type growing under similar conditions, he found that “the amount of carbon added by these trees between 100 and 150 years of age is greater than the amount added between zero and 50.”
In addition to carbon storage capabilities, old forests are pivotal in controlling regional and global water cycles through a process called evapotranspiration, by which water is transferred from the land to the atmosphere. Due to deeper and more complex root systems as well as larger canopies and leaves, old forests capture more water and release it as vapor into the atmosphere.
“Old forests have the genetic competence to do this work,” Masino says. “It’s not done by meadows. It’s not done by grassy areas. It’s not done as effectively by forests that have been cut or planted. It’s these ancient systems that have the complexity to bring water to themselves. And in doing that, they’re bringing it to the rest of the landscape. Once you start cutting the landscape, you’re drying it out.”
Masino, who also has a joint appointment in neuroscience and psychology at Trinity College, emphasizes the importance of designating natural areas appropriately and allowing more room for proforestation.
“It’s urgent to decide where we intend to prioritize natural processes, where we are doing research, and what areas we are dedicating for our resource needs,” she says. “Nature needs room to breathe. We can’t leave everything open to manipulation and extraction. It’s deadly.”
She says that planting trees on streets, on campuses or in parks is good for temperature regulation, flood protection and creating habitat, but these trees don’t grow up in a web of life. Planting trees in a forest, too, can risk disrupting the dynamic complexity of evolved and evolving genetic knowledge.
Wildlife dependent on old growth
Over on the West Coast, University of Oregon professor emeritus Beverly Law has studied forests for decades. She describes watching three logging trucks, each with a giant log from an old, single tree strapped to the back, passing in a procession while waiting at an intersection on her bike, a frequent occurrence on her way to work at the university in the late 1980s.
“There are plant and animal species that rely on these old forests for their survival. You take away the forest, and they’re gone,” Law says. “It’s important to have diverse genetics in the forest. Some of them will be more genetically able to withstand climate change than others. You don’t know which ones they will be. That is why genetic diversity within species is important.”
Mature forests are crucial to the survival of certain critically endangered animals that rely on the connected canopies or the soil-rich forest floor. Preserving the biodiversity of the Pacific Northwest, which hosts forests more than a thousand years old, is especially dire. According to a 2022 paper published in Environmental Chemistry Letters, old growth forests retain a number of species from both the top and bottom of the food chain, such as the Olympic salamander (Rhyacotriton olympicus), the Del Norte salamander (Plethodon elongatus) and the two species of tailed frog (Ascaphidae). Losing them forever could kick off a cascade effect and result in severe consequences for the environment.
The spotted owl (Strix occidentalis), too, depends on old-growth forests in the Pacific Northwest, requiring the specific environment for roosting and nesting, and remains a central figure in forest management debates.
Such hulking ancient trees are the eyes of the woods, having stood through changing years and the changing climate.
“Ten to 12% of old-growth forests are left [in the US], and it’s insane that people are still trying to cut them down,” Law says. “They are the only survivors of American handiwork. Is it man’s dominion over the forest? We should have reverence, considering they’re all that’s left.”

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.
The concept of the “technosphere” aims to reveal the immense scale of our collective impact. The concept was first introduced by US geologist Peter Haff in 2013, but paleobiologist Jan Zalasiewicz has since popularised the term through his work. The technosphere encompasses the vast global output of materials generated by human activities, as well as the associated energy consumption.
Since the agricultural revolution some 12,000 years ago (when we started building cities and accumulating goods), human enterprise has steadily grown. However, our impact has surged dramatically over the past couple of centuries. This surge has since transformed into exponential growth, particularly since 1950.
The technosphere is indicative of how humans are increasingly emerging as a global force on par with the natural systems that shape the world. The transformation that is needed to reduce our impact is therefore equally large. And yet, despite growing awareness, there has been a lack of concrete action to address humanity’s impact on the planet.
To comprehend the sheer magnitude of the technosphere, it is best visualised. So here are four graphs that capture how our collective addiction to “stuff” is progressively clogging up planet Earth.
1. Weighing the technosphere
In 2020, a group of Israeli academics presented a shocking fact: the combined mass of all materials currently utilised by humanity had surpassed the total mass of all living organisms on Earth.
According to their findings, the collective weight of all life on Earth (the biosphere) – ranging from microbes in the soil, to trees and animals on land – stands at 1.12 trillion tonnes. While the mass of materials actively used by humans, including concrete, plastic and asphalt, weighed in at 1.15 trillion tonnes.
The technosphere weighs more than all life on Earth (trillion tonnes):
The relative weights of the active technosphere and biosphere. The active technosphere includes materials that are currently in use by human activities. The biosphere includes all living things. Elhacham et al. (2020), CC BY-NC-ND
This graph offers a glimpse into the immense size of humanity’s footprint. But it likely only scratches the surface.
When accounting for the associated byproducts of the materials used by humans, including waste, ploughed soil and greenhouse gases, the geologist and palaeontologist, Jan Zalasiewicz, calculated that the technosphere expands to a staggering 30 trillion tonnes. This would include a mass of industrially emitted carbon dioxide equivalent to 150,000 Egyptian Pyramids.
2. Changing the Earth
Remarkably, human activity now dwarfs natural processes in changing the surface of our planet. The total global sediment load (erosion) that is transported naturally each year, primarily carried by rivers flowing into ocean basins, is estimated to be around 30 billion tonnes on average. However, this natural process has been overshadowed by the mass of material moved through human action like construction and mining activities.
Humans change the Earth’s surface more than natural processes (billion tonnes):

3. Transporting ‘stuff’
Our ability to transport fuel and products worldwide has facilitated the trends shown in the preceding graphs. Humans now transport these materials over increasingly vast distances.
Shipping continues to be the primary mechanism for moving materials around the globe. Since 1990, the amount of materials that are shipped around the world has increased more than threefold – and is continuing to grow.
How shipping has grown since 1980 (million tonnes):

4. The growth of plastics
Plastic stands out as one of the main “wonder materials” of the modern world. Due to the sheer speed and scale of the growth in plastic manufacturing and use, plastic is perhaps the metric most representative of the technosphere.
The first forms of plastic emerged in the early 20th century. But its mass production began following the second world war, with an estimated quantity of 2 million tonnes produced in 1950. However, the global production of plastic had increased to approximately 460 million tonnes by 2019.
This surge in plastic manufacturing is a pressing concern. Plastic pollution now causes many negative impacts on both nature and humans. Ocean plastics, for example, can degrade into smaller pieces and be ingested by marine animals.
Plastic manufacturing (million tonnes) has grown exponentially since 1950:
Humanity’s escalating impact on planet Earth poses a significant threat to the health and security of people and societies worldwide. But understanding the size of our impact is only one part of the story.
Equally important is the nature, form and location of the different materials that constitute the technosphere. Only then can we understand humanity’s true impact. For example, even the tiniest materials produced by humans, such as nanoplastics, can have significant and far-reaching consequences.
What is clear, though, is that our relentless pursuit of ever-increasing material output is overwhelming our planet.
Editor’s note: Climate change can not be addressed without stopping the extinction and plastics crisis. Every day, an estimated 137 species of plants, animals and insects go extinct due to deforestation alone. Microplastics have been detected in more than 1,300 animal species, including fish, mammals, birds, and insects. A global plastic treaty will only work if it caps production. Bangladesh is about to implement its existing law regarding plastic usage by strictly banning single-use plastic and, gradually, all possible plastic uses.
Scientific models can never account for all of the interconnected relationships within planetary systems’ boundaries. That is one reason why catastrophe predictions are always being pushed ahead.
There is simply no way the current economic system can persist indefinitely on a finite planet. Unfortunately, COP16’s primary goal is critical to striking a sustainable balance between human civilization and the natural world. That is an impossibility. We must tackle the underlying causes of biodiversity loss, including fossil fuel extraction, mining, industrial agriculture, intensive livestock farming, large-scale infrastructure projects, and monoculture tree plantations, basically civilization.
It is time to end civilization. Everything that claims existence must lose it; this is the eternal law. Power never gives up power willingly; it can only be broken with struggle. Nature is struggling to survive; we should help it.
Wildlife, climate and plastic: how three summits aim to repair a growing rift with nature
By the end of 2024, nearly 200 nations will have met at three conferences to address three problems: biodiversity loss, climate change and plastic pollution.
Colombia will host talks next week to assess global progress in protecting 30% of all land and water by 2030. Hot on its heels is COP29 in Azerbaijan. Here, countries will revisit the pledge they made last year in Dubai to “transition away” from the fossil fuels driving climate breakdown. And in December, South Korea could see the first global agreement to tackle plastic waste.
Don’t let these separate events fool you, though.
“Climate change, biodiversity loss and resource depletion are not isolated problems,” says biologist Liette Vasseur (Brock University), political scientist Anders Hayden (Dalhousie University) and ecologist Mike Jones (Swedish University of Agricultural Sciences).
Earth’s fraying parasol “How hot is it going to get? This is one of the most important and difficult remaining questions about our changing climate,” say two scientists who study climate change, Seth Wynes and H. Damon Matthews at the University of Waterloo and Concordia University respectively.
The answer depends on how sensitive the climate is to greenhouse gases like CO₂ and how much humanity ultimately emits, the pair say. When Wynes and Matthews asked 211 authors of past reports by the Intergovernmental Panel on Climate Change, their average best guess was 2.7°C by 2100.
“We’ve already seen devastating consequences like more flooding, hotter heatwaves and larger wildfires, and we’re only at 1.3°C above pre-industrial levels — less than halfway to 2.7°C,” they say.
There is a third variable that is harder to predict but no less important: the capacity of forests, wetlands and the ocean to continue to offset warming by absorbing the carbon and heat our furnaces and factories have released.
This blue and green carbon pump stalled in 2023, the hottest year on record, amid heatwaves, droughts and fires. The possibility of nature’s carbon storage suddenly collapsing is not priced into the computer models that simulate and project the future climate.
However, the ecosystems that buffer human-made warming are clearly struggling. A new report from the World Wildlife Fund (WWF) showed that the average size of monitored populations of vertebrate wildlife (animals with spinal columns – mammals, birds, fish, reptiles and amphibians) has shrunk by 73% since 1970.
Wildlife could become so scarce that ecosystems like the Amazon rainforest degenerate, according to the report.
“More than 90% of tropical trees and shrubs depend on animals to disperse their seeds, for example,” says biodiversity scientist Alexander Lees (Manchester Metropolitan University).
“These ‘biodiversity services’ are crucial.”
The result could be less biodiverse and, importantly for the climate, less carbon-rich habitats.
Plastic in a polar bear’s gut
Threats to wildlife are numerous. One that is growing fast and still poorly understood is plastic.
Bottles, bags, toothbrushes: a rising tide of plastic detritus is choking and snaring wild animals. These larger items eventually degrade into microplastics, tiny fragments that now suffuse the air, soil and water.
“In short, microplastics are widespread, accumulating in the remotest parts of our planet. There is evidence of their toxic effects at every level of biological organisation, from tiny insects at the bottom of the food chain to apex predators,” says Karen Raubenheimer, a senior lecturer in plastic pollution at the University of Wollongong.
Plastic is generally made from fossil fuels, the main agent of climate change. Activists and experts have seized on a similar demand to address both problems: turn off the taps.
In fact, the diagnosis of Costas Velis, an expert in ocean litter at the University of Leeds, sounds similar to what climate scientists say about unrestricted fossil fuel burning:
“Every year without production caps makes the necessary cut to plastic production in future steeper – and our need to use other measures to address the problem greater.”
A production cap hasn’t made it into the negotiating text for a plastic treaty (yet). And while governments pledged to transition away from coal, oil and gas last year, a new report on the world’s energy use shows fossil fuel use declining more slowly than in earlier forecasts – and much more slowly than would be necessary to halt warming at internationally agreed limits. The effort to protect a third of earth’s surface has barely begun.
Each of these summits is concerned with ameliorating the effects of modern societies on nature. Some experts argue for a more radical interpretation.
“Even if 30% of Earth was protected, how effectively would it halt biodiversity loss?” ask political ecologists Bram Büscher (Wageningen University) and Rosaleen Duffy (University of Sheffield).
“The proliferation of protected areas has happened at the same time as the extinction crisis has intensified. Perhaps, without these efforts, things could have been even worse for nature,” they say.
“But an equally valid argument would be that area-based conservation has blinded many to the causes of Earth’s diminishing biodiversity: an expanding economic system that squeezes ecosystems by turning ever more habitat into urban sprawl or farmland, polluting the air and water with ever more toxins and heating the atmosphere with ever more greenhouse gas.”
Editor’s note: Mass media news about war raises concerns about death, injury, and refuge of humans, the war on nature is rarely highlighted. But warfare always means ecocide on a large scale and wildlife and nature often take more time to recover than it is capable of. In Ukraine, 80% of wildlife is already on the brink of extinction, with the Russian aggression even more species and individual animals are getting lost. Therefore it’s a relief to have organisations like UAnimals who rescue pets and wildlife in emergency situations and raise international awareness about the destruction in nature and national parks.
The Ottawa Convention also referred to as the “Mine Ban Treaty,” prohibits the use, stockpiling, production, and transfer of anti-personnel landmines (APLs). Some key current and past producers and users of landmines, including the United States, China, India, Pakistan, and Russia, have not signed the treaty.
For Ukrainian activists, rescuing the dogs of war — not to mention the cats, swans, bats, bears and other wildlife — often means putting their own lives on the line.
Saving Ukraine’s injured and displaced animals during wartime often means seeing the worst elements of Russian cruelty.
“When a territory is liberated, our team goes there and we speak with the people who survived the occupation,” says Olga Chevhanyuk, chief operating officer of UAnimals, Ukraine’s largest animal-rights organization. “And each time we hear that when the Russians entered the town, they started shooting animals for fun, starting with dogs just walking the streets and ending with huge farms and shelters. Sometimes it’s probably a matter of manipulation, getting people scared. But mostly it’s no reason at all, just because they can.”
Originally founded to oppose inhumane conditions in circuses, the nonprofit UAnimals has shifted its mission to rescuing and caring for domestic animals and wildlife devastated by Russian aggression.
Working with local volunteers and shelters, they’ve helped tens of thousands of animals since the war began a year ago, including dogs and cats, horses, deer, swans, birds of prey and bats — even large predators like bears. In January alone they rescued more than 9,600 animals, provided food and medicine to thousands more, rebuilt shelters, and helped fund operations throughout the country.
They’ve also found themselves purchasing supplies not traditionally used in animal rescues.
“Before the war, you never think of buying helmets for your team,” Chevhanyuk says.
And then there’s the human toll: The nonprofit has contracted with psychologists to provide on-demand assistance to its team in the field. “So now they can have a session with the psychologist when they’re overwhelmed,” she says.
But this is all about saving more than individual animal lives and human minds. It’s about saving the soul of a country.
UAnimals has started calling the Russian war an ecocide — the deliberate destruction of the natural environment.
“Nowadays 20% of Ukraine’s nature conservation areas are affected by war,” Chevhanyuk says. “Russians occupy eight national reserves and 12 national parks, and some of the national parks are land-mined. Holy Mountains National Park is 80% destroyed. Some of them are destroyed 100%, meaning there are no plants, no animals, and no buildings which people use to heal animals. The land is littered with remains of destroyed objects, like tons of oil and burned products.”
Landmines are among the worst problems. They kill humans and animals indiscriminately, start fires, and will take years to mitigate. About 62,000 square miles of Ukraine may be contaminated with landmines. “This is greater than the size of Illinois,” according to information provided by a U.S. State Department official. “The United States is investing $91.5 million over the coming year to help the government of Ukraine address the urgent humanitarian challenges posed by explosive remnants of war created by Russia’s invasion.”
Cleaning up the pollution will require even more funding and effort. The war has caused at least $37 billion in environmental damage, a Ukrainian NGO said in November.
UAnimals predicts it could take more than a decade to repair the damage, but Ukraine’s wildlife doesn’t have that much time. “More than 80 species of animals in our country are on the verge of extinction and may completely cease to exist due to Russian aggression,” Chevhanyuk says. “Some of them are the steppe eagle, black stork, brown bear, Eurasian lynx, barn owl and eared hedgehog.”
While many of these species also exist in other countries, Chevhanyuk says wildlife has been an important element of Ukrainian folksongs, art and symbology — the very fabric of its culture — for centuries. “Being humane and treating animals as something really important and equal — this is one of the things which differs us a lot from Russians. And that’s, I believe, a part of our future victory.”
UAnimals continues to ramp up its fundraising and recovery efforts while expanding its network of shelters outside the country — a necessary step, as Ukrainian shelters and reserves are rapidly filling to capacity with animals too wounded ever to be released back into the wild.
“We have big shelters for bears, for example,” Chevhanyuk says, “but they are already full. I’m afraid that if something happens, we’ll need to bring these animals abroad. So we are very grateful to all our partners in different countries because there’s a big need right now.”
The organization is also tapping back into its activist roots to bring international attention to conditions in Ukraine. In February they organized Stop Ecocide Ukraine rallies in four U.S. cities — Atlanta, Austin, New York and San Antonio — that each attracted hundreds of people.
In a way, this is a return to form. “We used to create huge animal-rights marches in 30 Ukrainian cities every September,” Chevhanyuk says. “But since the war started, we are more focused on the emergency.”
And the international community has started to take notice. Last month the Parliamentary Assembly of the Council of Europe passed a resolution to “build and consolidate a legal framework for the enhanced protection of the environment in armed conflicts” — steps that support establishing ecocide as a new international crime.
“From a legal perspective, this is really encouraging,” says Jojo Mehta, cofounder and executive director of Stop Ecocide International, “because if you put severe harm to the living world on the same level as severe harm to people, if you say ecocide is as bad, wrong and dangerous as genocide, you’re creating a mental rebalance.”
It could still take years for ecocide to become international law. Meanwhile, the destruction of Ukraine continues, as do recovery efforts.
“If our team knows there is an animal to rescue,” Chevhanyuk says, “they will go in.”
Editor’s Note: Since main stream media gives so much attention to COP28 UN Framework Convention on Climate Change (UNFCCC), a lot of people are familiar with it. Climate change is posed as the main environmental issue that we are facing right now. While DGR believes that climate change is a threat, it is by far not the worst. Other pressing issues, like biodiversity loss, are often sidelined by mainstream media. As a result, many people do know what COP14 UN Convention on the Conservation of Migratory Species of Wild Animals (CMS) is. Biodiversity preservation requires habitat restoration, hardly something that anyone could gain profit from. Climate change, on the other hand, has provided many opportunities for corporations, in the name of “green” energy transition. We believe that climate change is a symptom of industrial civilization. Continuation of the process via “renewable” energy will only worsen all the ecological crisis that we are facing now, including climate change. Ending industrial civilization, protecting species and restoring habitats is the only way to actually address these issues.
Nearly Half of Migratory Species Populations Decline
While some migratory species listed under CMS are improving, nearly half (44 per cent) are showing population declines.
More than one-in-five (22 per cent) of CMS-listed species are threatened with extinction.
Nearly all (97 per cent) of CMS-listed fish are threatened with extinction.
The extinction risk is growing for migratory species globally, including those not listed under CMS.
Half (51 per cent) of Key Biodiversity Areas identified as important for CMS-listed migratory animals do not have protected status, and 58 per cent of the monitored sites recognized as being important for CMS-listed species are experiencing unsustainable levels of human-caused pressure.
The two greatest threats to both CMS-listed and all migratory species are overexploitation and habitat loss due to human activity. Three out of four CMS-listed species are impacted by habitat loss, degradation and fragmentation, and seven out of 10 CMS-listed species are impacted by overexploitation (including intentional taking as well as incidental capture).
Climate change, pollution and invasive species are also having profound impacts on migratory species.
Globally, 399 migratory species that are threatened or near threatened with extinction are not currently listed under CMS.

Until now, no such comprehensive assessment on migratory species has been carried out. The report provides a global overview of the conservation status and population trends of migratory animals, combined with the latest information on their main threats and successful actions to save them.
Billions of animals make migratory journeys each year on land, in rivers and oceans and in the skies, crossing national boundaries and continents, with some travelling thousands of miles across the globe to feed and breed. Migratory species play an essential role in maintaining the world’s ecosystems, and provide vital benefits, by pollinating plants, transporting key nutrients, preying on pests, and helping to store carbon.
The main focus of the report is the 1,189 animal species that have been recognized by CMS Parties as needing international protection and are listed under CMS, though it also features analysis linked to over 3,000 additional non-CMS migratory species. Species listed under the Convention are those at risk of extinction across all or much of their range, or in need of coordinated international action to boost their conservation status.
Most worryingly, nearly all CMS-listed species of fish – including migratory sharks, rays and sturgeons – are facing a high risk of extinction, with their populations declining by 90 per cent since the 1970s.
Analyzing the threats to species, the report shows the huge extent to which the decline in migratory species is being caused by human activities.
The two greatest threats to both CMS-listed and all migratory species were confirmed as overexploitation – which includes unsustainable hunting, overfishing and the capture of non-target animals such as in fisheries – and habitat loss, degradation and fragmentation – from activities such as agriculture and the expansion of transport and energy infrastructure.
The State of the World’s Migratory Speciesreport will provide scientific grounding and policy recommendations to set the context and provide valuable information to support the deliberations of the UN wildlife conservation conference (CMS COP14) starting today in Samarkand, Uzbekistan.
The convention also adopted a resolution urging parties not to engage with or support deep-sea mining until more scientific evidence is acquired. This resolution garnered criticism from the secretary-general of the International Seabed Authority (ISA), the U.N.-mandated body that governs deep-sea mining in international waters.
While attendees say COP14 had many successes, some experts say that more action and resources are required to keeping species from sliding toward extinction. – Mongabay
