Deep sea mining impacts visible for 'many decades'
- Scientists in Britain evaluated how deep-sea mining in the Clarion-Clipperton Zone affects ecosystems and concluded it can disrupt habitats for marine life, causing long-term damage.
- Mining companies are increasing operations to extract valuable metals from the deep sea as demand for electric car batteries rises, posing unprecedented threats to ocean biodiversity.
- Research indicates that sediment plumes from mining could harm midwater animals and affect food webs, highlighting the need for further studies on ecological impacts.
- Scientists in Britain assessed the lasting impact of mining tracks in the Clarion-Clipperton Zone, finding that removal of nodules disrupts habitats for marine organisms and threatens biodiversity.
