I’m confident that in a hundred years, eating meat will be regarded in the negative way we now view racism or sexism – an ugly, demeaning, and unnecessary act. Like smoking, it will simply fall out of fashion because we’ll find better and healthier alternatives, although we’ll still occasionally eat humanely reared-and-killed animals. Note that I still eat meat even though I should know better.
The interesting thing about eating meat is that it encapsulates a multitude of sins. You might worry about its impact on your own health; or perhaps on the environment, given the amount of water and land that a cow requires and the methane greenhouse gases it produces; or of course, on the life and suffering of the animal itself.
From an environmental standpoint, we should be eating far fewer cows and far more chickens, since the latter require less energy input to grow for a given calorie, and therefore (all things being roughly equal) produce less of negative impact. Or we should forget about the chickens and eat sustainably caught-or-farmed fish, which are even more energy efficient and have the smallest carbon footprint.
But what about from a suffering standpoint? You can feed far more people with a single cow than a single chicken, so if we want to reduce the suffering of animals, maybe we should be eating cows. But are cows more sentient than chickens? I don’t know how you measure that. And maybe the environmental impact of a single cow produces more suffering on other sentients than a chicken.
I feel like I’m taking utilitarianism to a place far beyond its ability to survive. I should probably read more Peter Singer.
