A triple-whammy of rising temperatures, increased acid levels and lack of oxygen is destroying the world’s oceans, according to scientists at the Rio+20 Earth Summit. Experts warn that small island states are being hit especially hard, with impacts on health, food and livelihoods.

This film explains what we can do to help corals stay alive.
