Oceans cover over 70% of our “blue” planet and are vital to its health. For instance carbon moves in and out of the ocean and can be stored there for thousands of years.

They are also the largest habitable space on the planet and house many different organisms.

But there’s a great deal that scientists still don’t know about the world’s oceans.

Proposed mining of seabed could destroy unstudied ecosystems and disrupt vital carbon-storing functions, says naturalist

Sir David Attenborough has urged governments to ban deep sea mining, following a study warning of “potentially disastrous” risks to the ocean’s life-support systems if it goes ahead.

The study, by Fauna and Flora International (FFI), warns proposed plans to mine the seabed could cause significant loss of biodiversity, disruption of the ocean’s “biological pump”, and the loss of microbes important for storing carbon. The process, requiring machines operating thousands of metres under the sea, could also create plumes of sediment that smother areas far from the mining sites and kill wildlife.
