Nature's own acidic ocean


Carbon dioxide emissions from human activities are acidifying the oceans and threaten a mass extinction of sea life, a top ocean scientist has warned.

This should give scientists a very good idea of how species will adapt to acidity or not, as Roger Harrabin has been finding out.
