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
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.
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.
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.
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.
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.
On Friday, August 30, Applied Energy Services Corporation (AES), a global utility and power generation company, submitted a proposal to Santa Fe, New Mexico county commissioners to build a 700-acre solar facility with a battery energy storage system (BESS).
On September 5th, a thermal runaway fire started at the AES-built SDG&E (San Diego Gas and Electric) Battery Storage Facility in Escondido, California. (With a thermal runaway fire, excessive heat causes a chemical reaction that spreads to other batteries.) Authorities issued a mandatory evacuation order for the immediate area, and a “shelter in place” order for areas as far as over a mile away from the fire. (To shelter in place, people must go indoors, shut doors and windows, and “self-sustain” until emergency personnel provide additional direction.) Schools up to three miles away from the fire were evacuated Thursday and canceled for Friday. 500 businesses closed.
As of this morning, Saturday, September 7th, officials have not yet lifted orders to evacuate and shelter in place.
On social media, people have reported smelling “burning plastic” inside their homes (despite windows being closed) and feeling ill.
People from Oceanside to Encinitas encountered a strong chemical smell starting around 5 pm Friday, the 6th. Around 8:30 pm, San Diego County Air Pollution Control District officials said that this smell was not related to the BESS fire in Escondido. Due to the odors’ fleeting nature, they were unable to identify its source.
This is the 3rd AES BESS thermal runaway fire in five years. Officials predict that it could take up to 48 hours to extinguish.
A May 2024 battery fire in Otay Mesa, California kept firefighters on the scene for nearly 17 days. They sprayed eight million gallons of water on the site. The county’s hazmat team tested water runoff and smoke and reported no toxic or dangerous levels. (Is the keyword in this last sentence “reported?”)
For a list of battery energy storage “failure incidents,” see Electric Power Research Institute’s database. Globally, 63 utility and industrial-scale battery energy storage systems endured failure events from 2011 to 2023. After South Korea, the U.S. has experienced the most major battery energy storage-related fires, with California (six, with this Escondido fire) and New York (four) reporting the most incidents.
Back in Santa Fe County, petitioners emailed and hand-delivered a request to county commissioners on July 23 and August 23 to enact a moratorium on AES’s solar facility and battery energy storage system. Commissioners did not review these petitions before AES submitted its application on August 30th. A moratorium cannot apply to a pending application.
AES’s Escondido Battery Energy Storage facility has 24 BESS battery containers. The corporation plans to install 38 battery containers at its Rancho Viejo BESS facility.
Please also read my September 5th post, 21 questions for solar PV explorers, and check out Shauna and Harlie Rankin’s video, “Government announces 31 million acre land grab from U.S. ranchers (for solar and wind facilities).” It explains that federal officials and corporations have joined forces to install “renewable power” corridors—five miles wide, 70 miles long, and larger—around the U.S. by 2030. These corridors will cover farm and ranchland with solar and wind facilities.
I also highly recommend Calvin L. Martin’s August 2019 report, “BESS Bombs: The huge explosive toxic batteries the wind & solar companies are sneaking into your backyard.” Part 1 and Part 2. I recommend reading this report even though powers-that-be removed its videos.
According to basic engineering principles, no technology is safe until proven safe. Will legislators continue to dedicate billions of dollars to subsidizing solar power, wind power, battery storage and EVs? Will commissioners and regulators say, “We have to expect some thermal runaway fires in order to mitigate climate change threats?” Or, will they build safety features into BESS like this firefighter suggests? Will they protect the public and insist on certified reports from liability-carrying professional engineers that all hazards have been mitigated before they permit new facilities and new battery storage systems?
1. Do you agree with Herman Daly’s principles—don’t take from the Earth faster than it can replenish, and don’t waste faster than it can absorb?
2. Should solar PV evaluations recognize the extractions, water, wood, fossil fuels and intercontinental shipping involved in manufacturing solar PV systems?
3. How should a manufacturer prove that slave laborers did not make any part of its solar PV system?
4. Should evaluations of solar PVs’ ecological impacts include impacts from chemicals leached during PVs’ manufacture?
5. Should evaluations assess the ecological impacts of spraying large-scale solar facilities’ land with herbicides to kill vegetation that could dry and catch fire?
6. Does your fire department have a plan for responding to a large-scale solar facility fire on a sunny day—when solar-generated electricity cannot be turned off?
7. Since utilities can’t shut off rooftop solar’s power generation on a sunny day, firefighters will not enter the building: they could be electrocuted. Meanwhile, every solar panel deployed on a rooftop increases a building’s electrical connections and fire hazards. How/can your fire department protect buildings with rooftop solar?
8. Solar panels are coated with PFAs in four places. Panels cracked during hailstorms can leach chemicals into groundwater. Who will monitor and mitigate the chemicals leached onto land under solar panels?
9. To keep clean and efficient, solar panels require cleaning. Per month, how much water will the solar PV facility near you require?
10. Covering land with paved roads, parking lots, shopping malls, data centers…and large solar facilities…disrupts healthy water cycling and soil structure. Should evaluations assess the impact of these losses? How/can you restore healthy water cycling and soil structure?
11. Since solar PVs generate power only when the sun shines—but electricity users expect its availability 24/7—such customers require backup from the fossil-fuel-powered grid or from highly toxic batteries. Should marketers stop calling solar PVs “renewable,” “green,” “clean,” “sustainable” and “carbon neutral?”
12. Inverters convert the direct current (DC) electricity generated by solar panels to alternating current (AC)—the kind of electricity used by most buildings, electronics and appliances. (Boats and RVs do not connect to the grid; they use DC—batteries—to power their appliances.) Inverters “chop” the electric current on building wires, generating a kind of radiation. What are the hazards of such radiation? How/can you mitigate it?
13. At their end-of-usable-life, solar PVs are hazardous waste. Who pays the ecological costs to dispose of them?
14. Who pays the financial bill to dispose of solar PV systems at their end-of-usable-life? If you’ve got a large-scale solar facility, did your county commissioners require the corporation to post a bond so that if/when it goes bankrupt, your county doesn’t pay that financial bill?
15. After a solar facility’s waste has been removed, how/will the land be restored?
16. From cradles-to-graves, who is qualified to evaluate solar PVs’ ecological soundness? Should the expert carry liability for their evaluation? Should consumers require a cradle-to-grave evaluation from a liability-carrying expert before purchasing a solar PV system?
17. Do solar PVs contribute to overshoot—using water, ores and other materials faster than the Earth can replenish them?
18. If overshoot is a primary problem, and climate change, loss of wildlife species and pollution are consequences of overshoot, do we change our expectations of electric power, devices, appliances and the Internet?
19. Can you name five unsustainable expectations about electric power?
20. Can you name five sustainable expectations about electric power?

Editor’s note: Protecting the ocean means life protection, our ecosystems depend on intact and clean oceans. Even though the aim is to protect 30% of the planet, it’s not clear what conservation actually means worldwide. That leads to ineffective conservation measures and demands more knowledge about oceanic ecosystems and also implementing it. For the most part protected areas don’t need to be managed, they just need to have humans leave them alone.
There’s never been more momentum for protecting the ocean, but new research finds that many efforts fail to protect endangered species — or have barely gotten off the drawing board.
Ocean ecosystems and the marine wildlife that depend on them are under threat as never before. Between overfishing, climate change, plastic pollution, and habitat destruction, it’s a bad time to be a prawn, cod, seabird, or whale.
There’s no single silver bullet solution to the biodiversity crisis, but in recent years, many people in the environmental community have focused on the goal of “30 x 30”: protecting 30% of the planet by the year 2030. Many nations have made promises toward that goal, including the United States, which has adapted it into the “America the Beautiful” initiative.
Measurable goals like this provide nations with clear, quantifiable conservation goals that others in the international community can follow, verify, or use to identify shortfalls and push for more action.
At the same time, many experts warn that number-based targets like “protect 30%” lend themselves to incentives to arguably-kinda-sorta protect as much as possible, rather than protecting the most ecologically important areas. Governments, for instance, can use what’s euphemistically referred to as “creative accounting” — counting things as protected that probably should not be considered protected.
Two new research papers examine some of this creative accounting in the ocean. Together, they stress important things to keep in mind when creating protected areas and when assessing their usefulness.
To Protect a Species, Protect Areas Where They Actually Live
A surprisingly common issue in area-based conservation happens when a government declares a new protected area to help save a threatened species of concern…without first checking to see if the species actually lives within those boundaries.
It happens more often than you might think. A new study published in the Journal of Animal Ecology looked at 89 marine protected areas in Europe that are supposed to protect diadromous fish species (those that migrate between ocean and fresh water, like salmon or some eels) of conservation concern.
Their findings are shocking: Many of these areas protect habitats where those fish species do not live, and very few of them protect the most important core habitat for any diadromous fish species.
“A marine protected area should be an area that protects part of the marine environment,” says Sophie Elliott of the Wildlife Conservation Trust, the study’s lead author. “I say ‘should’ because there are a lot of parks that don’t have enough thought put into them. Quite often things are done quickly without thinking or understanding the situation.”
Sometimes this happens because of limited resources for scientific study. In other words, according to Elliot, we simply don’t know enough about species’ habitat use to protect their key habitat, at least not yet. This is known as the rare-species paradox: Endangered species are often hard to find and study, especially in the vast ocean, so it can be hard to understand what habitat qualities they need to thrive, even if we can hypothesize that protecting certain regions will mitigate some of the threats the species face.
Other times government officials, in search of positive publicity, announce a new protected area that was studied but wasn’t intended to protect a species.
“We had a series of MPAs that were supposed to have measures in place to protect certain species,” Elliott says. “But then an extra species got tacked on to the stated goals of the MPA, and it wasn’t effective for that species.” She declined to identify examples, given the political sensitivities of some of these protected areas.
In addition to gathering more data and always basing protected-area design on the best available data, Elliott recommends a more holistic approach to designating future protected areas.
“When people think about putting MPAs in place, look at the whole range of biodiversity that exists within it, because there might be many endangered and protected species,” she says. “You need to know what’s in that MPA and do ecosystem-based management” — management focusing on the whole ecosystem and not just individual species. It’s the difference between protecting cod by establishing fishing quotas versus protecting cod by also managing their habitat and predators and food and other things that eat that food. “We’ve long been calling for that, but we aren’t really working toward it at all,” she says.
What Counts As ‘Protected’ Varies More Than You Think
Another key issue in marine protected area management is what should count as “protected.”
Some areas restrict oil and gas extraction but allow any and all fishing. Some allow swimmers and other recreation, while others say people can’t even go scuba diving.
In one glaring recent example, the advocacy group Oceana U.K. found evidence that the United Kingdom allows bottom trawling in many of its MPAs. Bottom trawling is a fishing method that’s extremely destructive to sensitive habitat types; it’s been compared to clear-cutting forests to catch rabbits.
“At the end of the day … there’s no one clear definition of what conservation means around the world,” says Angelo Villagomez, a senior fellow at the Center for American Progress who has studied the issue. “One of the negative externalities of the global push to protect 30% of the ocean is that some governments are more concerned with being able to say that they protected 30% of the ocean than they are concerned with delivering meaningful biodiversity protections.”
Villagomez and his colleagues have identified another big issue: According to their new analysis in the journal Conservation Letters, fully one-quarter of the 100 largest marine protected areas — as cataloged in the United Nations and IUCN’s world database of protected areas — are announced but not yet implemented. Many have no clear timeline of when the formal protections might be put into place, or what those regulations might look like.
For now, those areas exist on paper but remain unprotected in the real world. For example, the paper cites the OSPAR MPA network covering 7% of the Northeast Atlantic, which currently appears to have no concrete protections.
This wide range of rules and inconsistent protections makes it harder to protect the ocean — or to count it toward 30×30 goals.
Governments are not supposed to submit anything to the world database of protected areas until something is designated, “but they do, and that’s just the reality,” says Villagomez.
But here’s the biggest problem: The study found that many of the world’s largest MPAs lack the scientific knowledge, funding, and political support to be effective.
“We know that MPAs work when they are well designed and provided the funding to operate,” Villagomez told me. “But for about one-third of the MPAs we studied, based on everything we know about protected area science, they will never result in positive outcomes for biodiversity.”
The conclusions of these two papers are clear: Too many marine protected areas are poorly designed and sited in places where the species they’re ostensibly trying to protect do not actually live. Also, too many allow destructive extractive industries to operate, limiting the benefits of any protection.
Despite these setbacks, Villagomez remains optimistic about the future of MPA-based protections.
“The good news is that this works really well about one-third of the time — if you play baseball and you hit the ball 300 out of 1,000 times, you’re going to the Hall of Fame,” he says. “There’s a ton of science that shows that well-designed well-implemented MPAs work, and for one-quarter of the MPAS we looked at, they’re well designed and are just lacking funding for implementation.”

Editor’s note: Although Greenpeace has done many good things in the past, particularly their work that led to an international ban on whale hunting, it is astounding that they currently support offshore wind.

Scientists have found a source of ‘dark oxygen’ 4,000 meters below the surface of the Pacific in the target zone for deep sea mining. The discovery could have far-reaching implications for science and the wannabe deep sea mining industry. It’s often said that we know more about the surface of the moon than we do about the deep ocean. This new discovery of dark oxygen shows how true that is, and underlines the need to stop a new deep sea mining industry from targeting its source.
What is dark oxygen?
What scientists mean by ‘dark oxygen’ is that – in the total darkness of the very deep ocean – around 4,000 meters below the surface of the Pacific Ocean – oxygen is being produced – in the dark.
It’s previously been thought that oxygen on Earth is produced on land and at the surface of the ocean, where sunlight makes plant photosynthesis possible.
Plants on land are the biggest producers of oxygen, but marine algae and phytoplankton also produce it. These microscopic organisms perform photosynthesis in the ocean, which covers about 70% of the Earth’s surface.
Blue-green algae – or cyanobacteria – are some of the oldest organisms on Earth and can also produce oxygen. They were among the first to do so through photosynthesis, and they also need sunlight.
The common factor in oxygen production is sunlight – until this discovery of dark oxygen showed that oxygen is also being produced in another way in the deep dark sea.
Why is the dark oxygen discovery significant?
The dark oxygen discovery is being hailed as a groundbreaking scientific discovery, but it also has other implications.
Nick Owens, the director of the Scottish Association for Marine Science (SAMS) says: “The fact that we’ve got another source of oxygen on the planet other than photosynthesis has consequences and implications that are utterly profound.”
Andrew Sweetman, who was one of the SAMS scientists involved in the research, says in a video: “This research potentially sheds light on where life began on the planet. This discovery has shown that, well, maybe there was another source of oxygen a long time ago and aerobic life or life that breathes oxygen could have persisted before the rise of photosynthesis — and if it’s happening on our planet could it be happening on other planets too?”
But as well as those wider implications, the discovery has significant and immediate implications for the controversial deep sea mining industry which somewhat ironically sponsored the science.
Here’s the thing. This dark oxygen, instead of being produced by plants and sunlight, is being produced by strange potato-shaped metallic lumps found on the deep sea floor.
It turns out that these lumps – otherwise known as ‘polymetallic nodules’ – give off almost as much electricity as AA batteries! By reacting with salt water, their electrical charge produces oxygen way down there on the seabed of the deep ocean through a process known as ‘seawater electrolysis’ which splits seawater into hydrogen and oxygen.
So, these little metallic lumps, which the wannabe deep sea miners have been metaphorically calling ‘batteries in a rock’ actually turned out to be just that – and they’re producing dark oxygen that could play a critical role in the deep ocean ecology.
What the dark oxygen discovery means for deep sea mining
The discovery of metallic nodules producing dark oxygen has been a huge surprise to science which could even require a new way of thinking about how life first began on planet Earth.
But it could also be the final straw in the case against deep sea mining. It could stop the industry before they begin.
The discovery was made in the Clarion-Clipperton Zone (CCZ), a huge flat area of the seafloor that stretches between Hawaii and Mexico, where mining companies like The Metals Company have plans to start harvesting these very same nodules that turn out to be producing all this dark oxygen.
These oxygen-producing nodules could be supporting a whole range of known and unknown deep sea lifeforms. Dark oxygen could be a critical factor in the deep sea ecosystem!
Greenpeace and others have long said that this new extractive mining industry should not be allowed to start in the very deep ocean because the life there is so little understood, and the ecosystems are fragile and potentially vital for the health of the ocean and all life on Earth.
This new discovery underlines the point.
The timing is good because world governments are meeting in Jamaica right now to decide the fate of this new mining industry. They’ll be deciding whether or not to allow deep sea miners like The Metals Company to go ahead with their plans to drop giant mining robots onto the seafloor to start harvesting these life-sustaining nodules.
Greenpeace is in Jamaica arguing strongly that deep sea mining should not be allowed to go ahead – especially now that we know the deep ocean is another source of oxygen that could be vital for the health of the ocean and all of us who depend on it.
In the climate and biodiversity crisis, we know that nature, in all its diversity, must be protected.
