Reply #38: Being a vegetarian is, perhaps, more ethical in today's world

[WindRavenX]

Considering that it's energetically "wasteful" to eat a diet with a large amount of meat when it could be used to produce more plant matter for more consumption, I would say it's less a question of evolution and more of a question of ethics.

Biologically speaking, and I speak as a biologist with a concentration in mammalian evolution, we evolved from and as omnivores. But today, diets with a moderate-excessive amount of meat is both unethical (IMO) and unneeded for survival.

It is damaging to the planet to support meat-heavy diets, and I find it hard to eat meat anymore when I realize that the amount of resources that went into my chicken could have fed many, many more people for less of a cost to the environment, and the absence of a suffering chicken.
