I think it foolhardy to predict the absolute limits of human endurance. - Lewis Pugh

A massive turquoise glacier feeds into Magdalenefjord, with chunks of ice as big as buildings breaking off and landing in the water to float away as icebergs. As I swam past them, with my head in the water, I heard a tantalising sound: a snap-crackle-pop, just like Rice Krispies in milk. It was the sound of tiny air bubbles being released from the ice – air that had been trapped there as much as 3,000 years ago. To swim through this sound, I thought, is to swim in history.

I always feel nostalgic when I disembark (off a ship). It's not that I don't like land. I just love being at sea.

When we set aside MPAs we protect the marine habitat. When we do that, fish stocks recover. Which supports food security. When we create MPAs, we protect the coral, which protects the shoreline and provides shelter for fish. Marine Protected Areas are places people want to visit for ecotourism, so it's good for the economy. It has, if you'll pardon the pun, a ripple effect. Marine Protected Areas are good for the world economy, for the health of the oceans, for every person living on this planet.
