Human Carnivory Project

The human carnivory project emphasizes, in the broadest terms, the effects of humans eating meat on the environment and climate. Illustrated here are the effects of livestock populations on greenhouse gas emissions, biodiversity, riparian ecosystems, and iconic wildlife including wolves, lions, rhinos, and more.

The Human Carnivory Project has a youtube channel, check it out!
