What is a Ton of Carbon? When going on a flight you are told that you as an individual are putting tons of carbon into the atmosphere. I don't get this, if every one on a plane creates one ton of carbon thats 200/300 + Tons of carbon. But the plane does not carry anywhere near that weight in fuel. Also, a ton of an air borne substance is a huge volume. Surely it takes a huge amount to create a Ton of something that weights almost nothing? What am I missing here?
