COWS: Destroying The World

Our atmosphere is slowly going away. Why? Cow farts, that's why. I know, it sounds silly. But it's very true. You see, cow farts have an invisible gas called methane. This methane is killing the atmosphere. Now, I have a somewhat crazy proposition to fix this deadly problem. Now, we'll have to dig out an EXTREMELY large pasture underground, probably the size of China. Underneath China. Anyway, after digging, we will have to install a simulated sun, and plant grass EVERYWHERE. Then there will be those milking machines installed too. After that, we will transport ALL the cows into this facility. If they don't all fit we will proceed with the appropriate procedure for turning cows into steak. There will be a tube system that allows us humans to get down into the pasture to retrieve all of our goods. If the methane becomes unbearable, another system will be installed to retrieve the  goods for us. As for the methane, if we don't get it out of the room all the cows will die, so each cow will have a fart collector attached to its butt, where all the methane will gather. As soon as they are full, the methane will go up the tube attached to the collector and into gas stations and methane will be used as the world's replacement oil because it is very flammable. If this doesn't work then....well...Steak Party???
