Eat Meat and Kill The Planet! What tha? Eat babies instead...

Hey, it's Marco! The intense grazing and feedlot methods are destroying the pasture lands, the streams, the rivers, and the atmosphere. Small farmers are being ruined by what is happening. Here is the story... read on! But! Just in case you're wondering what you're about to read, consider this: 
It takes roughly 16 pounds of grain to produce one pound of beef. An immense amount of energy is needed to run the tractors, fuel the spray planes, power the combines to harvest them—all for the raising of beef, pork, or chicken. Eighty percent of American grain production is used to feed meat animals. It now takes a gallon of gasoline to produce a pound of grain-fed beef in the U.S. To sustain the yearly beef requirements of an average family of four requires over 260 gallons of fossil fuel. When that fuel is burned, it releases 2.5 tons of additional carbon dioxide into the atmosphere, equivalent to the amount of CO2 the average car emits in six months of normal operation. All that for one pound of grain-fed beef! (Jeremy Rifkin, Beyond Beef, pp. 224-225). So eat babies instead!
