BBC News – Deep sea mining ‘gold rush’ moves closer

Extinction risk

And Prof Paul Tyler, also a biologist, of the National Oceanography Centre, warned that unique species would be at risk.

“If you wipe out that area by mining, those animals have to do one of two things: they disperse and colonise another hydrothermal vent somewhere or they die.

“And what happens when they die is that the vent will become biologically extinct.”

However, marine chemist Prof Rachel Mills, of the University of Southampton, called for a wider debate about mining generally on the grounds that we all use minerals and that mines on land are far larger than any would be on the seabed.

She has carried out research for Nautilus Minerals, a Canadian firm planning to mine hydrothermal vents off Papua New Guinea.

“Everything we are surrounded by, the way we live, relies on mineral resources and we don’t often ask where they come from,” she said.

“We need to ask whether there is sustainable mining on land and whether there is sustainable mining in the seas.

“I actually think it is the same moral questions we ask whether it’s from the Andes or down in the Bismarck Sea.”

This debate is set to intensify as the reality of the first mining operations comes closer.
