INTERVIEW The U.N. body charged with regulating deep-ocean mining will soon consider whether to permit the first project to move forward. But ecologist Lisa Levin, who has long studied the deep sea, worries that in the rush for key minerals, a pristine and important ecosystem will be lost. Few people know the deep ocean as intimately as Lisa Levin, an ecologist at the Scripps Institution of Oceanography. Not content with doing pure science, Levin, who has participated in more than 40 oceanographic expeditions, co-founded the Deep-Ocean Stewardship Initiative, a global network of more than 2,000 scientists, economists, and legal experts that seeks to advise policymakers on managing the ocean’s depths.Of particular concern to Levin now is the prospect of deep-sea mining. The tiny island nation of Nauru has notified the International Seabed Authority on behalf of its Canadian partner, the Metals Company, of its intent to seek a permit to mine in the Clarion-Clipperton Zone, a 1.7- million-square-mile region of the Pacific where polymetatallic nodules are scattered that have high concentrations of cobalt and other valuable minerals.The ISA, formed by the U.N. in 1994, is required to issue mining codes that would regulate deep-sea mining by July 9. If it fails to do so, some scientists and environmentalists fear that an controversial rule may allow mining to begin nonetheless. While Levin told Yale Environment 360 that she doubts we’ll see it happen this year, she too worries that pressure is mounting to start mining soon.Mining companies argue that land-based sources for these metals are running out and that they are critically needed for green technologies like producing batteries for electric vehicles and manufacturing solar panels and wind turbines. They also claim that mining in the deep sea will be less environmentally damaging than land-based mining.In an interview with e360, Levin disagreed. “It’s a highly destructive process,” she said. “People talk about sustainable mining. I think it’s an oxymoron in the deep sea. But society has to decide — should we do it, and is it worth the cost?” Levin collects a rock gathered by a remotely operated vehicle. Courtesy of the Schmidt Ocean Institute Yale Environment 360: The deep sea is viewed by many as a kind of watery desert. There may be a few creatures floating around down there, but people don’t think of it as a thriving ecosystem. Is that just wrong? Lisa Levin: There are actually surprisingly diverse and rich ecosystems, but sometimes the organisms are small, only a few millimeters in size. For example, in the nodule zone that they’re interested in mining, most of the animals are very, very small. We may think it is unpopulated, because we don’t see many big charismatic organisms there.
