I am often asked why I do it. At a simplistic level, I am passionate about swimming and I enjoy pushing boundaries. But there's a lot more to it than that. Through my swims I have had a unique perspective on climate change. I have witnessed retreating glaciers, decreasing sea ice, coral bleaching, severe droughts, and the migration of animals to colder climates. It's as a result of these experiences that I am determined to do my bit to raise awareness about the fragility of our environment and to encourage everyone to take action.

 Environment

But I've not always been in swimming trunks. I studied law at the University of Cape Town and the University of Cambridge, and then went on to work as a maritime lawyer in London. I now spend much of my time public speaking and lobbying world leaders to protect the environment.

We stand at a critical point in the history of the planet and the steps which we take over the next few years will determine the future of the natural world and the sustainability of mankind.

I will never forget the first time I saw a polar bear. I was in awe of its absolute beauty! I realised at that moment that I may be one of the last people to see them alive. Their habitat is melting away rapidly with climate change.

Through the medium of swimming, I want to raise awareness about the impact of our actions. They say that seeing is believing and it's certainly true. I hope that through my swims, and the filming and reporting of them, I can act as the eyes of the world. So, whether I'm swimming around islands which are fast disappearing due to rising sea levels, or swimming across parts of the Arctic which were previously frozen over, I will swim - and stand for the future of our planet.

I believe that each and every one of us can do something to ensure that future generations enjoy the sight of polar bears and the security of a sustainable world.

To start, we can all make simple changes to the way we live our lives - turning off lights, ensuring electrical appliances are not left on standby, considering more carefully the cars we drive, reducing our air travel, buying local produce, and installing energy saving light bulbs. Most importantly, let's only vote for politicians who put the environment at the very top of the agenda and let's demand legislation which safeguards our world.
