We already know that plastic is a top threat to marine life, with over 12.7 million metric tons of plastic waste entering the oceans each year. But a new study has found that 92% of global coral reefs surveyed, even remote reefs, are covered in plastics.
The study, published in the journal Nature, surveyed 84 coral reef systems, both shallow and deep, at 25 locations across the Atlantic, Indian and Pacific Oceans. They found that the coral reefs were more impacted than other marine ecosystems (outside of coastal ecosystems like beaches and wetlands) by plastic and other waste.
“Plastic pollution is one of the most pressing problems plaguing ocean ecosystems, and coral reefs are no exception,” Hudson Pinheiro, lead author of the study and biologist at the Center for Marine Biology of the University of São Paulo, said in a statement. “From macroplastics that spread coral diseases to fishing lines that entangle and damage the structural complexity of the reef, decreasing both fish abundance and diversity, pollution negatively impacts the entire coral reef ecosystem.”
The researchers found that the deeper into the oceans they studied, the more plastic they found. About three-fourths of the plastic debris found in the study was from fishing gear. Most of the plastic debris found, about 88% of the total debris, was larger than two inches.
“It was surprising to find that debris increased with depth since deeper reefs in general are farther from sources of plastic pollution,” Luiz Rocha, senior author of the study and curator of ichthyology at the California Academy of Sciences, said in a statement. “We are almost always the first humans to set eyes on these deeper reefs, and yet we see human-produced trash on every dive. It really puts the effect we have had on the planet into perspective.”
The researchers hypothesize that the higher amounts of trash at greater depths could be because of waves carrying trash away, humans collecting trash from shallow reefs, or shallow reefs growing over the debris.
In the study, scientists found that Comoros, a country of three islands off the coast of eastern Africa, had the highest pollution density. Here, they found about 84,500 pieces of debris per square kilometer.
The researchers recommended that in addition to improvements in waste management and reducing single-use plastic, there needs to be innovations in fishing gear to make it biodegradable.
“How can we change the ropes, the nets?” Pinheiro told NPR. “We need to find a biodegradable material, like made from fibers as we used to do before.”
We can also look to places that were found to have less plastic pollution, such as the Marshall Islands, for inspiration on curbing this pollution.
“Despite the disturbing overall trend, there were some places where we found relatively little debris, which shows us that there are effective strategies for preventing plastic pollution,” study co-author Bart Shepherd, director of the California Academy of Sciences Steinhart Aquarium, said. “If we act fast and employ science-based solutions, there absolutely is hope for coral reefs.”
This month, a small group of diplomats is meeting to hash out a plan that could affect the future of nearly half of Earth’s surface — including regions containing metals that are vital for the energy transition, like nickel, copper, cobalt, and manganese.
That group is the International Seabed Authority, or ISA, an autonomous international organization tasked with regulating mining on the ocean floor, in waters outside any nation’s jurisdiction. On July 9, the regulatory body missed an important legal deadline to finalize those rules. Now the ISA is scrambling to complete them, or agree to a fall-back plan, before companies start applying for deep-sea mining permits.
The stakes in this regulatory race are high. Some deep-sea ecosystems are rich in metals used in electric vehicle batteries, wind turbines, and solar panels. To transition off fossil fuels, the world needs to dig up enormous quantities of these metals, and deep-sea mining proponents say that can be done with less impact on the ocean floor than on land.
A low-impact mining industry is unlikely to materialize in the absence of ISA rules governing environmental standards and oversight. However, if a company submits a commercial deep-sea mining application before the ISA completes those rules — officially called the Mining Code — the agency will be legally obligated to consider the request nonetheless. Some industry watchdogs fear this will trigger a literal race to the bottom, in which companies destroy fragile seafloor ecosystems in the pursuit of profits.
But a catastrophic outcome is far from assured. Pradeep Singh, an ocean law expert at the Helmholtz Centre Potsdam who attends the ISA meetings and advises governments on deep-sea mining, says member nations have rallied behind the idea that there must be regulations in place before any deep-sea mining companies are given the go-ahead — and that there are several options on the table to ensure that outcome. States, Singh said, are starting to ask: “Do we really want to rush this process for the benefit of one private mining company?”
Singh is referring to The Metals Company, the Canadian mining firm at the center of the high seas hullabaloo. In the summer of 2021, the Pacific Island nation of Nauru gave the ISA notice that a subsidiary of the firm, which Nauru is backing as a state sponsor, intended to submit an application to begin deep-sea mining. The Metals Company is one of 18 commercial or state-backed entities that have received exploration permits from the ISA to test technology, take samples, and investigate the overall resource potential of deep-sea rocks called polymetallic nodules, in areas that each span nearly 30,000 squares miles. No company has been granted a contract to mine underwater.
In announcing The Metals Company’s plan to become the first, Nauru activated the “two-year rule,” an obscure legal provision that obligates the ISA to finalize mining regulations within that time frame, or consider any applications if the deadline passes before the rules are done. Nauru and The Metals Company might have been hoping that the ISA would buckle down and finish a rulemaking process that began in 2014. But the sudden imposition of a deadline came in the thick of the COVID-19 pandemic, which had caused ISA negotiations to grind to a halt.
Negotiations resumed last year, but at the end of the ISA’s last meeting in March, the Mining Code was far from complete. The next meeting of the ISA Council, the key group of negotiators tasked with hashing out its details, began on July 10 — a day after the two-year deadline passed.
If the ISA Council manages to finalize the Mining Code by July 21, it could be put before the entire ISA Assembly — including representatives of 167 countries and the European Union — for a vote at the end of the month. Many ISA observers think that’s extremely unlikely, considering the wide range of issues that still need to be worked out within the code itself, including setting the overarching environmental goals and objectives of deep-sea mining, public consultation processes related to environmental plans, and how compliance inspections will work. But Singh points out that the council did reach one important decision at its March meeting: that commercial deep-sea mining shouldn’t happen in the absence of regulations.
Part of the council meeting taking place this week will be devoted to discussing what the ISA should do if Nauru, or another country, submits an application for commercial deep-sea mining before the Mining Code is complete. The ISA could, for instance, decide that it will start considering applications immediately, but it will defer making any decisions about them until regulations are in place. Or it could grant an applicant’s mining plan “provisional” approval, but hold off on the negotiation of the final contract until the rulebook is finished. The ISA, Singh says, can also choose to reject any applications that don’t meet its standards. But in the absence of a Mining Code, it is unclear what standards it would base such a decision on.
More dramatically, the ISA could choose to impose a temporary pause or mining moratorium — something that major environmental organizations like Greenpeace, as well as multinational corporations like Google and Patagonia, have called for in recent years. “If governments are serious about their environmental credentials, they have to say no to deep-sea mining,” said Arlo Hemphill, a senior oceans campaigner at Greenpeace USA. “This is the moment to take the wind out of the sails of an industry that has no future.”
“A moratorium or pause is the only responsible way forward at the moment,” deep-sea biologist Diva Amon told Grist. Amon is lead author of a study, published Tuesday in Nature npj Ocean Sustainability, concluding that rising ocean temperatures will cause the range of commercial fish species like yellowfin tuna to overlap more with areas of the eastern Pacific where companies wish to mine. Also on Tuesday, several seafood groups released a letter calling for a pause on deep-sea mining until there is a “clear understanding” of its impacts on the marine environment.
But Singh feels that a pause or ban on mining is less likely than the ISA simply kicking the can down the road, considering that fewer than two dozen member states have voiced support for such action. (Their ranks, however, are growing: Ireland called for a “precautionary pause” on mining last week, while Canada came out in support of a moratorium on Monday.) “What’s more likely is that we’ll just extend the negotiations” into the fall or next year, Singh said.
Taking additional time to complete the regulations would also give the ISA an opportunity to sort out issues that are outside the scope of the Mining Code but intrinsically related to deep-sea mining. These include figuring out how to share the economic benefits of the industry in an equitable manner, and how to compensate developing countries whose land-based mining industries are harmed by competition at sea — something African nations have been particularly vocal about. That competition could be significant: The Metals Company estimates the area of the Pacific seafloor it wishes to mine contains enough nickel, manganese, copper, and cobalt “to electrify the entire U.S. passenger car fleet.” And it is just one company.
While many observers are worried about how the ISA will deal with mining applications submitted in the coming weeks or months, there also is no guarantee those applications will appear.
At the close of the ISA’s March meeting, Nauru stated that it “will not entertain an application for a plan of work” from The Metals Company in July to avoid influencing the ongoing negotiations. The nation did not promise to wait any longer. But Singh points out that states sponsoring mining companies expose themselves to potential legal liability for mining activities. One role of the Mining Code, Singh says, is to “set the parameters” of sponsor state liabilities.
“If you’re agreeing to sponsor a contract in the absence of regulations, you’re agreeing to sponsor a contract in the absence of protection for yourself,” Singh said. “You’re signing a blank check.” The government of Nauru did not respond to Grist’s request for comment.
A spokesperson for The Metals Company told Grist in an email that the company would prefer “to submit an application with exploitation regulations in place.” However, the spokesperson added that the firm retains “the legal right to submit an application in their absence and to have this considered by the Council.” The Metals Company will only submit an application for a commercial deep-sea mining contract after it completes “a high-quality, comprehensive, science-driven environmental and social impact assessment,” the spokesperson said. The company declined to respond to critics’concerns that rushing into deep-sea mining with little understanding of its long-term effects on ecosystems could significantly harm biodiversity and processes like deep-sea carbon sequestration.
The Metals Company also declined to say when it might be ready to apply for a commercial deep-sea mining contract. In an investor update in May, the firm indicated that it planned to do so in the second half of 2023. But Andrew Thaler, a deep-sea ecologist and the CEO of Blackbeard Biologic, a marine science and policy consultancy, cautioned that corporate timetables are often optimistic, and that he takes all such projections with “a grain of salt.”
Thaler, whose doctoral research was sponsored by a deep-sea mining company and who has participated in best-practice and risk-management workshops for the industry, says that the majority of people involved with deep-sea mining see themselves as environmentalists. “They genuinely believe we are facing a planetary crisis,” Thaler said, and that they “found a way to get us off fossil fuels faster, and it’s going to involve some exploitation of seafloor.”
But Thaler worries that if the industry tries to push forward too quickly, it will undercut its own sales pitch as a lower-impact alternative to land-based mining.
Deep-sea mining companies have “an opportunity to prove there is a way to do commercial exploitation of natural resources that’s marginally more conscientious and sustainably minded,” Thaler said. “Why throw all that away just to get mining two years earlier?”

Following a tense debate, the European Parliament has voted in favor of a Nature Restoration Law that establishes legally binding targets to restore degraded natural areas in the European Union (EU). It is the first major piece of legislation to protect biodiversity in the EU in 30 years.
Members of Parliament (MEPs) said the restoration measures must cover at least one-fifth of the land and sea areas in the EU and be in place by 2030, a press release from the European Parliament said.
“The Nature Restoration Law is an essential piece of the European Green Deal and follows the scientific consensus and recommendations to restore Europe’s ecosystems. Farmers and fishers will benefit from it and it ensures a habitable earth for future generations,” said MEP César Luena, a Spanish politician who was one of the biggest champions of the measure, in the press release.
The bill passed 336 to 300, with 13 abstentions, and will now pass to a committee of European representatives, reported The New York Times.
Restoring ecosystems is essential to battling biodiversity loss and climate change, as well as reducing risks posed to food security, MEPs emphasized. They added that the new law does not interfere with the creation of renewable energy infrastructure, and does not require new protected areas to be created in the EU.
With more than 80 percent of European habitats suffering, the continent was in desperate need of a binding law to restore the continent’s wild spaces.
“European nature is in a dire state, but this vote shows that there is still hope to restore and grow what’s left,” said Špela Bandelj, project manager for Greenpeace Central and Eastern Europe Biodiversity, in a press release from Greenpeace. “So far governments and the EU have failed to act. The nature restoration law is a clear benchmark to judge them on their actions on the ground.”
Parliament said the new law must support international commitments by the EU, especially the Kunming-Montréal Global Biodiversity framework, which was adopted at the 15th Conference of Parties to the UN Convention on Biological Diversity in 2022.
“It’s a huge social victory,” Luena said, as The New York Times reported. “It’s good for everybody. Because if you have healthy ecosystems, then the economic systems which depend on these ecosystems are going to be healthy themselves.”
Before the law can take hold, EU countries must quantify the restoration area needed to achieve restoration goals for each type of habitat, and the European Commission must provide data on the conditions needed for long-term food security.
The possibility of restoration law targets being postponed in the event of exceptional socioeconomic circumstances was held open by Parliament.
Within a year of the law coming into force, assessments of any gap between available EU funding and the financial needs of restoration would have to be assessed by the Commission, and funds to make up the difference would need to be found.
The Commission has said that, for each euro invested in the new legislation, benefits of at least eight euros would be reaped.
Parliament will now begin negotiations on the final draft of the Nature Restoration Law.
“Our position adopted today sends a clear message. Now we must continue the good work, defend our ground during the negotiations with member states and reach an agreement before the end of this Parliament’s mandate to pass the first regulation on nature restoration in the EU’s history,” Luena said in the press release.
The Environmental Protection Agency is proposing strict standards on lead paint that would prompt the removal of lead in millions of buildings, including homes, schools, and daycare centers. The move was set in motion by a lawsuit from environmental groups alleging that the EPA’s lead standards were too lax to protect public health.
Even after decades of efforts to reduce lead exposure from gasoline, pipes, and paint, half of children in the U.S. have detectable traces of lead in their blood, according to a study in 2021 that tested more than 1 million kids under the age of 6. Those who live in low-income neighborhoods and in older homes are at the highest risk.
“We know that no level of exposure to lead is good for our children. Zero,” said Janet McCabe, the EPA’s deputy administrator, at an announcement of the proposal in Newark, New Jersey, on Wednesday. The metal has been found to damage children’s brains, slow their growth, and cause developmental and behavioral problems, according to the Centers for Disease Control and Prevention.
While the United States banned lead paint nearly half a century ago, the rules didn’t require removing the toxic substance from existing buildings. An estimated 31 million houses built before the 1978 ban still have lead paint, and nearly 4 million of those homes are occupied by families with children younger than 6. The EPA’s new rule would virtually prohibit lead dust, reducing exposure for between 250,000 and 500,000 children under the age of 6.
Any sign of lead in a home or childcare center would classify it as a lead hazard. That would in turn trigger disclosures — say, to the families of kids attending the daycare or to prospective home buyers — and potentially require that the lead source be removed. The only exception is for contamination that existing cleanup methods can’t get rid of.
The plan was decades in the making. In 1992, after scientists found lead exposure was widespread among children, Congress passed a law requiring the EPA to establish the first hazard standard for lead in dust. But the agency was slow to create the standard, waiting until 2001 to do so, and it failed to tighten the rules when scientific evidence showed that lead was a health hazard even at the smallest levels of exposure.
Court battles ended up forcing the agency to revisit its lead standards — twice. The most recent lawsuit, filed 2019 by the Sierra Club, Earthjustice, and other public health and environmental groups, alleged that the EPA’s revised standards were still insufficient. In 2021, the U.S. 9th Circuit Court of Appeals ordered the EPA to set its standards based on health effects, as opposed to factors like feasibility and testing capabilities — a decision that prompted the EPA’s new proposed rule. Before an EPA regulation becomes final, it has to move through a public comment period.
Environmental groups applauded the EPA’s new, stricter proposal but admonished the agency for decades of delay. “Today’s proposal, which finally acknowledges that any exposure to lead at any level is a hazard, is a gigantic leap forward in this country’s long-delayed efforts to eliminate, or at least significantly reduce, lead exposures,” said Eve Gartner, the director of Earthjustice’s Crosscutting Toxics Strategies program, at the EPA’s announcement on Wednesday.
Removing lead from buildings won’t necessarily erase the threat entirely. For example, a recent investigation from the Wall Street Journal unearthed a hidden source of lead contamination in the environment: a countrywide network of lead-coated cables laid by telecom giants such as AT&T and Verizon that have gone unnoticed by regulators. It’s another sign that removing lead, with its once-ubiquitous use in the country’s construction, remains a daunting task.
