A remarkable find from Bill McKibben:

“Last week, I noticed a comment in passing: forty percent of the world’s shipping, one commenter insisted, consists of just sending fossil fuels around the world to be burned.

“That can’t be right, I thought – what about all the other things we have to ship. There’s grain, and lumber, and iron ore, and cars, and a zillion containers loaded with tennis rackets and dog toys and 70-inch TVs. But no – a little research makes clear that in fact if you add up all the tonnage, something very close to forty percent of all the shipping on earth is just devoted to getting oil and coal and gas (and now some wood pellets) back and forth across the ocean.”

The optimistic conclusion is fairly straightforward:

“If and when we make the transition to solar power and wind power, we will not just stop pouring carbon into the atmosphere, and not just save money – we will also reduce the number of ships sailing back and forth by almost half.”
