"The idea that carbon dioxide is a carcinogen that is harmful to our environment is almost comical. Every time we exhale, we exhale carbon dioxide. Every cow in the world, you know when they do what they do you've got more carbon dioxide." —Minority Leader John Boehner on This Week
First, no one is suggesting that carbon dioxide is a carcinogen (causes cancer). Secondly, a fart joke from the Republican minority leader? ZING! Thirdly, arguing that carbon dioxide is harmless because we exhale carbon dioxide is like saying: Duh! Humans are 70 percent water! It's comical to suggest a person could drown in water!
