I would like to think that the UK is the international leader on these issues. As I said to Mr Carmichael, this is an international matter: all this literally moves around the world. I have recently been to the United States and Canada, and we are working on this with Canada, which has the G7 presidency this year. We are leading the way on dealing with ocean acidification, and I assure the hon. Gentleman that that is very much at the top of the agenda for this Government.
