Ocean acidification is a threat to marine life and our food supply, UK Environment Secretary Hilary Benn warned on 14 December, in a speech to mark Oceans Day at the United Nations Climate Change conference. Addressing delegates in Copenhagen, Mr Benn explained that in the past 150 years, the oceans have absorbed half of all the carbon dioxide that we as human beings have generated. “We need to tell the story of the damage we are doing to our seas as we seek to do something about it here in Copenhagen this week,” he added.
