Ten million percent! This has been a huge bugbear of mine for so long.

I also feel like people use the whole "the top ten corporations produce most of the green house gas" thing as an excuse not to be better. Yes there's systemic issues and we shouldn't waste our time trying to scold people who individually make very little difference. But a collective is made up of individuals acting in concert, and if you make the worst decisions you're still part of the problem, even tho you shouldn't be expected to solve the crisis alone.

Even if you don't care about the killing of animals, it's still a good idea to eat less meat from the perspective of greenhouse gas emissions. You don't get to say "chevron pollutes more than me" when eating meat is probably among the most carbon intensive things most people do.

Also, those corporations burn so Mich carbon to sell stuff to people. They're doing it partly to satisfy consumer demand.
