Summary
Scientists found that machines used for deep-sea mining harmed over a third of the seabed animals in a study conducted in the Pacific Ocean. They discovered around 4,000 animal species living in the area, with 90% being new species. Deep-sea mining is controversial and not yet allowed until more is understood about its environmental effects.
Key Facts
- The study showed a 37% decrease in animal numbers in mined seabed areas compared to untouched ones.
- Scientists found 4,000 animals, 90% of which were previously unknown species.
- Deep-sea mining is controversial due to environmental concerns.
- The research was conducted at the request of The Metals Company but was independent.
- Machines used in mining disturbed the top five centimeters of the seabed, where most animals live.
- Pollution from mining can slowly harm some animal species.
- In nearby areas, biodiversity impacts were not as severe.
- The study took place in the Clarion-Clipperton Zone, a vast area rich in critical minerals.
