This article says that the 15 largest container ships emit more pollution (nitrogen oxide and sulphur oxide) than all the cars in the world! One ship equal to 50 million cars.
Why the heck are we regulating cars so much instead of putting nuclear power on the 15 largest ships?
50 ships may offset all the industrial pollution as well. (Guessing.)
We could do away with carbon credits, winter blends, catalytic convertors, drive Volkswagon diesels again, and actually get better fuel mileage.
