The weird thing is why are so many people so hellbent on the meat part?
There's a lot of things with higher impact, like..
- Installing solar panels on your home
- Minimizing car usage, especially solo car usage
- Minimizing air travel
- Eating and buying locally
But none of these really have ardent advocates or people that get offended when people go "Nah fam, i'm good".
If your philosophy is about animal rights, argue about those. Don't trojan horse with environmental issues. (Which, anyway, apply mostly to beef. Pork and chicken are minor.)
(I don't eat beef, for the record. I do eat quite a lot of pork and chicken, though.)
(Also for the record, i spent my first paychecks installing a solar roof, i don't own a personal car, travel by train whenever possible, and do my best with local markets.)
The leading cause of co2 emissions is cows
What? no.
