 Marine Species Face Extinction Risk, Courtesy Carbon Emissions
Carbon emissions have put marine species at risk of ecological catastrophe. The oceans are acidifying at a faster rate, due to carbon emissions, threatening the survival of the species.

When seawater becomes too acid, corals and shrimp-like plankton at the bottom of the food chain cannot survive.

The knock-on effects can lead to widespread mass extinction of marine species - and is believed to have done in the past.

In the last 100 years atmospheric carbon dioxide has risen to about 30 percent above pre-industrial levels.

New research has shown that even during periods of past mass extinctions the ocean acidity rate nowhere near matched what it is is today.
