Deep Sea Mining

Deep-Sea Mining Could Cause 25x The Biodiversity Loss Of Land-Based Mining

June 30, 2023 Cristen Hemingway Jaynes, EcoWatch. , , ,
Rising demand for metals like nickel, cobalt, copper and manganese to make batteries used in smartphones and electric vehicles, along with depleting land-based deposits, has led to increased interest in deep-sea mining. But research suggests that the process of extracting mineral deposits from the ocean floor could destroy habitats and decimate species. According to a new report from British nonprofit financial think tank Planet Tracker, mining the ocean’s depths could cause as much as 25 times more biodiversity loss than terrestrial mining, reported Reuters. And the financial cost of repairing that damage would be twice as much as extracting it.

Deep Sea Mining Threatens More Than The Seafloor

July 13, 2020 Climate and Capitalism. , , ,
Interest in deep-sea mining for copper, cobalt, zinc, manganese, and other valuable metals has grown substantially in the last decade and mining activities are anticipated to begin soon. Deep-sea mining poses significant risks, not only to the area immediately surrounding mining operations but also to the water hundreds to thousands of feet above the seafloor, threatening vast midwater ecosystems. Currently, 30 exploration licenses cover about 580,000 square miles of the seafloor on the high seas and some countries are exploring exploitation in their own water as well. Thus far, most research assessing the impacts of mining and environmental baseline survey work has focused on the seafloor. However, large amounts of mud and dissolved chemicals are released during mining and large equipment produces extraordinary noise—all of which travel high and wide. Unfortunately, there has been almost no study of the potential effects of mining beyond the habitat immediately adjacent to extraction activities.
