My thanks to the oceans, and the people they have brought me to.

Oceans are a bit like people. Every ocean is different, and to me they have distinct personalities. The Arctic is the black ocean – literally like an inkpot. You put your arm in and your hand just disappears. The Pacific is a rich, royal blue. The Indian Ocean is the most benevolent; it’s warm and kind and turquoise. The Atlantic can be rough and cold.But it's the Southern Ocean that gives you a glimpse of what the oceans must have been like before man touched them. It’s like an aquatic Garden of Eden, just teeming with penguins and seals and killer whales.I know how very privileged I am to have swum in all five oceans. In each one I have seen evidence of how our actions are impacting them. That part is not a pretty sight. I’ll never forget the beach of plastic debris in the middle of the Arctic. Thousands of kilometres from the nearest town, there were sheets of red plastic, pieces of rope, tangles of thrown-away plastic junk.Wherever you are in the world you will find evidence that we have impacted our oceans. The one thing they all have in common is that they are under threat. But I believe we can change this. I hold fast to my dream of restoring our oceans to their former splendour.I want to take this opportunity to thank you for helping me to be a voice for the oceans. It is only through the continuing support of people like you, people who have taken the time to hear me speak, who have bought my book, signed up for my blog, or followed me on Facebook and twitter, that we are able to make a difference. Your support and enthusiasm gives me hope for our future. And with hope, anything is possible.Until then, peace, love, and Merry Christmas,LewisP.S. I am about to launch an exciting new expedition. I look forward to sharing it with you very soon…
