The plain fact of the matter is that humans evolved on an almost exclusively meat-based diet and to this day thrive on an almost exclusively meat-based diet.
Not only are plants toxic for humans, but widespread agriculture results in the loss of insect life, due to the massive use of insecticides, which in turn contributes to the loss of bird life due to the loss on insect life.
Plant-based diets are terrible for human health and terrible for the environment, what with all the fossil-fuel-based fertilizers. The sooner we come to our senses and massively invest in regenerative herding the better off we'll be as a species.
We should all be eating mostly red meat every day, with maybe a bit of fruit here and there -- this is by far the healthiest diet both for the human body and for the Earth as our home.
And no, I'm not trolling -- this is my sincere and deeply-held belief.
