 And that isn't just the movement of goods, because there are huge amounts of goods moving around on the ocean. I think it's something people don't realize is that the ocean is the kind of engine of the global economy. There are 11 billion tons of goods moving around on container ships every year, an extraordinary number, and that kind of underpins every economy on Earth, but also huge amounts of fossil fuels. So 40% of what's being moved around by ships is actually fossil fuels. It's coal and gas and oil being moved around.
