hasn’t even been 300 years since we had giant herds of buffalo roaming this country. We removed mega fauna and replaced it with a different species.

I really think that’s methane stat is exaggerated because it pretends like the planet wasn’t covered in cows before we started killing everything.

It likely wasn’t. Everyone eating meat is a relatively new phenomenon 
There are a lot of really interesting opinions here on this sub. Anthropologists must come together and renounce their evidence of ancient hunting practices and accept what ever your opinion is. Got it. Everyones an environmental scientist/ agricultural expert/ anthropologist on here.
