Ocean acidification risks mass extinction of sea life

Increasing acidity of the oceans due to rising carbon dioxide (CO2) emissions pose a major threat to aquatic life, scientists are warning.

“I am very worried for ocean ecosystems which are currently productive and diverse,” said Carol Turley of Plymouth Marine Laboratory. “I believe we may be heading for a mass extinction, as the [current] rate of change in the oceans hasn’t been seen since the dinosaurs. It may have a major impact on food security. It really is imperative that we cut emissions of CO2.”
