Deep-sea mining extracts minerals that can cause significant damage to ecosystems. The deep sea is home to diverse and poorly understood organisms, many of which have yet to be discovered. Mining operations destroy these ecosystems, which can lead to the extinction of some species. 

Extracting minerals from the deep sea requires large amounts of energy and resources, can lead to greenhouse gas emissions and exacerbate climate change. Deep sea mining could cause irreversible changes to this environment and have a significant impact on its biodiversity.
