In 1800, Sir Issac Newton orbited Earth w/ 5 cows to prove cow farts help us. His science in his Treatise: "Vacce Quam Tenere Simul in Mundo" demonstrates the theory of Forward Reversal. Far from hurting the Ozone Layer, it keeps Earth's magnetic field, magnetic. He stated it clearly saying: "Though cow farts are unpleasant to the smell, they hold the world together. For every action (bovine farting) is an exact & opposite reaction (people eating fast food hamburgers)." I hope this clears this up. Always at your service, Vince Vance
