The Race Against Time to Save the Environment

I'm just wondering whether you ever think about the people and communities who undertake fishing, even whaling in the oceans that you've swam in. I'll never forget one swim which I did down in Antarctica in a place called Deception Island where there were whale bones piled high. We came within an inch of pushing the whale into extinction but we're now going for the tiniest life down there on which everything relies - krill. So it's now in a race against time to save the environment. If we carry on the way we carry on we will have no more fish.
