The always excellent Ben Adler has a new article in the American Prospect describing the relationship between meat consumption and the environment. I had always been aware that livestock was responsible for some environmental damage but I never appreciated the scale of the problem a steak poses to global climate change:
…meat consumption plays a bigger role in greenhouse gas emissions than even many environmentalists realize. The production and transportation of meat and dairy, particularly if you include the grains that are fed to livestock, is much more energy-intensive than it is for plants. Animals, especially cattle, also release gases like methane and nitrous oxide that, pound for pound, are up to 30 times more damaging than carbon dioxide. Internationally there is an additional cost to animal agriculture: massive deforestation to make land available for grazing, which releases greenhouse gases as the trees are burned and removes valuable foliage that absorbs carbon dioxide. As a result, according to a 2006 United Nations report, internationally the livestock sector accounts for 18 percent of all greenhouse gas emissions — more than the transportation sector.

Wow. Incidentally, I was actually a vegetarian for the first few months at Yale (given the limited vegetarian options at the U of M, vegetarianism wasn’t really an option there) but gave it up after a trip to Iceland where I was tempted by loads of delicious meat. Now, however, I’m starting to reconsider whether or not I should make my vegetarian vows once again.
On a whole though, I’m rather uncomfortable with individual action that’s aimed at solving large social problems. For example, I scoff at environmentalists who buy Priuses in an effort to ‘save the earth’ because really, one person’s decision to change their behavior matters so little at the macro level. I know, I know, you can make the argument that it’s better to do something than nothing, that one person can make a difference, that everyone is a unique and precious snowflake, etc; however, as a general rule I’m not terribly willing to give up something I enjoy if others don’t have to as well.
What I am willing to do though is take these issues into consideration at the ballot box. I’m very supportive of policies that make everyone give something up, even it constrains an activity I enjoy. This is why I think I would be willing to embrace a tax on meat—a sort of sin tax on carnivores if you will. After all, if we’re willing to consider taxing soda, why not meat too? Both, if consumed in excess, have damaging health effects and both impose negative externalities on the rest of society. Seems as if both meat and sugar would make prime targets for our cash-strapped treasury.
