“A UK scientist studying volcanic vents in the ocean says they hold a grave warning for future marine ecosystems.
These vents have naturally acidified waters that hint at how our seas might change if atmospheric carbon dioxide levels continue to rise.
They are conditions that would make it harder for corals and similar organisms to make the hard parts in their bodies.
Dr Jason Hall-Spencer’s work suggests our oceans could lose perhaps 30% of their biodiversity this century.
The Plymouth University researcher has been presenting his latest findings to a major conference in Vancouver, Canada.
“I am investigating underwater volcanoes where carbon dioxide bubbles up like a Jacuzzi, acidifying large areas of the seabed, and we can see at these vents which types of organisms are able to thrive and which ones..”
