Thus, a vegan diet may be seen as a sensible response by people who want to minimize their involvement with the meat industry in an industrial capitalist society. But this is not a universal context, whereas veganism markets itself as a universal solution. PETA has declared that you can't be a meat-eating environmentalist, and most vegans believe this line or toe it explicitly. What vegans have failed to think out is that industrial capitalism has not existed forever, nor have human societies always been ecocidal or abusive towards animals. In fact, to avoid eurocentric conclusions vegans must admit that the first and the very best environmentalists eat meat. I refer to a number of indigenous societies, past and present, that have the best track record of living in harmony with the environment and seeing other species as their extended families. Especially since vegans put so much emphasis on the impacts of an individual's lifestyle, they (being nearly all residents of wealthy countries) are deluding themselves and the broader communities to which they advertise their image as the preeminent environmentalists, considering that these omnivorous non-capitalist societies had a much lower ecological footprint and a much deeper affinity for animals than anyone socialized in an industrial society can ever gain in their lifetimes.
