Rio+20 (16/06/2012) – Richard Feely, Senior Scientist at U.S National Oceanic & Atmospheric Administration talks to Pavilion TV about the problem of the acidification of the world’s oceans in terms of sustainable life of the marine species and ensuring the continued availability of fish for peoples’ diets.

He explains that it was once thought a good thing that the ocean’s absorbed up to a quarter of the carbon emissions released into the atmosphere from human activities but how more recently scientists have observed a 30% increase in the acidity of our oceans.
