Carbon dioxide is the major greenhouse gas causing global warming.
Everybody breathes in oxygen and breathes out carbon dioxide. So the simple solution to global warming is to simply not breathe out. Doing this for just 4 hours a day will slow global warming tremendously. We hope you will cooperate with this program. Since bats have been trained to carry anvils and drop them on people refusing to comply, you can understand the importance of doing your bit. We thank you again. And no cheating by wearing hardhats.
