More Productive Cows Means Less Gas?
The worldwide dairy industry is responsible for more greenhouse gas emissions than vehicle traffic, thanks to the land, water, and feed that go into milk production, as well as the methane produced by cows' digestive systems. Agence France Presse reports that a researcher at Cornell University found that giving one million cows a controversial growth hormone would allow dairies to produce the same amount of milk with far fewer cows. Researcher Judith Capper says the result would be the same as removing 400,000 cars from the roads.
