Really mad cowDon't let their big brown eyes and bulging udders fool you. Cows are not our friends. They are poisoning the very air we breathe at an alarming rate. Cows are in the top five contributors to global warming, and it's all because they burp. Alot. This releases unbelievable amounts of methane gas into the environment. What comes out of their other end is also methane rich, and methane traps more than 20% more heat than carbon dioxide.

Maybe Sir Paul's brain is still muddled from his battle to extricate himself from the clutches of the evil one-legged former call girl. Was he even a vegetarian before she leeched on? Possibly. But in a recent chat with PETA, Sir Paul said everyone should give up meat to stop the meat industry's blight on the planet. "I would urge everyone to think about taking this simple step to help our precious environment and save it for the children of the future."

If there were less cows, there would be less methane emitted by their multi-stomached digestive systems. Therefore, I think it's imperative that everyone grabs a big juicy burger or a gloriously rare filet mignon on a regular basis, because even meat eaters can make a difference.
