I've seen some glaciers in the world which have been, which are just turquoise blue blue glaciers up in the Arctic. It's tragic to think that because of climate change, because of man's actions, they're melting away.

I was very, very lucky because I started swimming when most of the landmarks in the world had not been swum.

I do have spare time and I love to read, and I love just to go to a national park and just relax and just think. But most of the time, it's swimming or talking.

I'm one of the lucky people that, my job is my passion, is my hobby. I hope this doesn't sound arrogant: I truly feel that this is what I'm meant to do, to swim and to talk about protecting the environment, my two passions.

I love swimming, swimming's my passion and I hope I swim until the last day of my life, so I really, really do enjoy swimming, but swimming for me is simply a way of carrying a message.

Britain has bred many great explorers, but they seem to get so little coverage compared to soccer and rugby players.
