CARBON:
Carbon dioxide is the gas that causes global warming. It makes the Earth hot the same way a car gets hot when it’s in the sun. We put carbon dioxide into the atmosphere with almost everything we do, including driving and using electricity. We’re going to have to be much more careful about carbon dioxide, or else the Earth will become too warm.
