You are the single biggest feature of the surface of the Earth. You cover 28% of the planet, more than all the land put together, and contain enough water to fill the moon. You also contain, almost as an afterthought, four-fifths of the world’s islands. If your coastline were to be stretched out straight, it would reach around the world five times, and a lot of people would get very wet indeed.
