A new survey reveals that areas targeted for deep sea mining in the Pacific Ocean are home to vulnerable sperm whales and dolphins. The Metals Company's mining plans could harm marine life, according to researchers from the University of Exeter and Greenpeace. The survey involved a mission by Greenpeace's Arctic Sunrise ship and highlighted concerns over the environmental impact of mining. The upcoming ISA summit will discuss regulations for mineral extraction, while some countries have imposed moratoriums or bans on deep sea mining. The Metals Company defends its operations against accusations of harming marine ecosystems.
