Green Eggs & Ham: What Meat Is Best For The Environment?
It’s obvious every time we write a post on vegetarianism: lots of people love meat. But are some meats better for the planet than others? And what about the half-vegetarian’s flesh of choice, fish?
In answer to the first question, the Slate‘s Nina Rastogi says: go ahead, chow down on some bacon. Well, kind of. The greenest meat is actually poultry, because it’s so efficient: a calorie of chicken protein requires only 5.6 calories of fossil fuels, as opposed to 20 to 40 for beef. But pork is also somewhat more environmentally-friendly than beef, because pigs fart less and breed more than cows. Methane gas expelled by livestock contributes to global warming, and the more offspring an animal has per year, the fewer resources expended on breeding. Sadly for hamburger lovers, beef is the worst offender. It’s bad for humans, as underscored by a new study (although, to be fair, this study also fingers hot dogs, which everyone knows are made of lips and assholes), and it’s also bad for the planet. Cows use the most land, cause the most global warming, and contribute most to a kind of water pollution called eutrophication, which can kill fish.
