Dairy and meat consumption on the scale humanity is currently consuming is very new.
The industrial mass rape of billions of animals and horrifyingly massive numbers of livestock animals now on earth, is not a ‘natural’ thing either.
Wild mammals make up only 4% of mammal biomass on earth now, 62% is livestock and 34% is humans.
Just because your ancestors had no other means of survival but to consume animals and their excretions, does not mean that it is healthy, natural, or wise for to be breeding and consuming livestock at the scale people are now.
You’re not alone. I stress binge on melons (or apples, depending on the season), popcorn and miso soup full of leafy veg and rice noodles.
