Deep-sea mining has larger-than-expected impacts on sea life, study says

The fast-growing practice of deep-sea mining poses significant threats to important sea creatures, such as fish, shrimp, corals, and sponges, according to a new study.

Researchers say they found evidence that disturbances caused by deep-sea mining can slash populations of nearby ocean animals roughly in half and impact marine life across larger areas than scientists have previously thought.

The study, published Friday in Current Biology, adds to evidence that mining the deep ocean for minerals used to make electric vehicles and renewable energy components has harmful ecological impacts that must be weighed against the climate benefits of transitioning away from fossil fuels.

Although deep sea mining may be one way to meet the world’s growing demand for certain metals, “it also has the potential to greatly disrupt many deep-sea habitats,” the new paper states.

“Is it worth it to get these [metals] and mess up the sea versus mess up somewhere else? I don’t know, but we have to use everything we have to make the right call,” said Travis Washburn, an ocean floor ecologist and author on the new study.

Amid Biden push for electric vehicles, debate grows over “green” mining

Minnesota, long known as the Land of 10,000 Lakes, is a heralded haven for people and wildlife alike, a state rich in natural resources.

But now, a nickel mine proposed for northern Minnesota poses a threat to the stability of precious wetland ecosystems, according to critics trying to block the project. Though backers of the mine claim it will be an environmentally friendly operation that provides crucial material for the production of electric vehicle batteries, challengers say the mine could actually create more environmental problems than it will solve.

The battle illustrates one of many challenges arising as the Biden administration pushes for a rapid transition away from fossil fuels and toward so-called clean energy. In May, the Biden Administration paused the environmental review process for an Arizona copper mine in the face of similar concerns from Indigenous tribes about what the mine there might do to water quality.

“We’re not opposed to mining, but we have to ensure that these activities do not endanger our natural environment or our Indigenous communities,” said Kelly Applegate, commissioner of natural resources for the Mille Lacs Band of Ojibwe. A community of Mille Lacs members live near the site designated for the Minnesota mine, which would sit just outside the tiny town of Tamarack.

In push to mine for minerals, clean energy advocates ask what going green really means

By Shannon Kelleher

A traveler crossing the expanse of northern Nevada desert known as Thacker Pass might see a wasteland – nothing but scrubby sagebrush out to the rim of the caldera, where the mountains cut the horizon.

But for local tribal members, the land they call Peehee Mu’huh, or “Rotten Moon,” is a hallowed place of remembrance and sacred burial site. In 1865, US cavalrymen massacred their ancestors at the site, including children and elders. Members of the Fort McDermitt Paiute and Shoshone Tribe visit often, praying and sharing food together in the windswept wilderness.

Now, a contingent of forces that includes the US government and a large Canada-based mining corporation are pushing to make Thacker Pass a gateway to the future– they seek to carve into the landscape, extracting massive quantities of lithium for use in batteries that could power one million electric vehicles (EVs) per year. The mineral deposit at Thacker Pass is considered the largest known lithium source in North America, making it an important resource for “clean energy” technology that mitigates harmful climate change by curbing fossil fuel dependence.

Staunch opposition has formed around the project from local tribes as well as environmental advocates who argue the mining operation would threaten vulnerable wildlife and dangerously pollute the air and water just as similar mining project have in the past. But earlier this month a US District Court judge largely upheld the US Bureau of Land Management (BLM)’s 2020 decision to approve the mine.

Though opponents vow to keep fighting, the court ruling allows Canada-based Lithium Americas to advance construction plans for the $2.2 billion project, and General Motors Co. (GM) recently announced plans to invest $650 million in the mine.

The Biden administration last year announced a series of incentives aimed at boosting supplies of lithium as well as other minerals such as nickel and cobalt, deemed “critical” for use in electric vehicle production and other renewable energy needs, saying increasing supplies will help “improve America’s energy independence, strengthen national security, support good-paying jobs…”

But the battle over Thacker Pass illustrates just how complicated the issue is as environmental advocates find themselves presented with these thorny questions: What does “going green” really mean? What is the true cost of the clean energy revolution? And will vulnerable communities inevitably pay that price?

“This story is the same everywhere,” said Ian Lange, a professor of economics at the Colorado School of Mines. “If you don’t want to mine for minerals, we’re going to keep drilling for oil and gas.”
