the meat industry put out decades of propaganda during the great depression & world wars to convince the western world to buy meat & dairy. truth is, humans have lived off plant based diets for millennia. ending factory farming is one of the easiest ways to combat climate change & corporations
Most people have consumed animal proteins the catch is they weren’t eating a lot meat regularly. One of my ancestors was upper middle class when he migrated to the USA and founded a small city. His journal talks about his meals and as a wealthy person with a dairy farm he still mostly had stew and rarely ate steak. He wasn’t eating animals all the time and that was 1840-80s. We need to go back to a time when eating a whole chicken among a family of four in a single meal almost never happened IF we continue farming animals which as you noted is a climate change nightmare.
- Humans have also been eating meat for millennia. We’re omnivores, and have always been opportunistic about what we eat
- Individuals cutting down their personal meat consumption won’t stop factory farming, but ending subsidies that make that practice highly profitable might
The only evolutionary reason humans have advanced brains is because of nutrient rich meat.
FYI that study has been successfully debunked shortly after it was written.
There are more recent claims of doubt against more meat = large brain though.
The fact still is that both meat and animal milk were a huge impact in early homo life.
It’s entirely possible that our capacity of language and advanced learning stems from non dietary sources.
