this isn’t a joke. factory farming uses more fossil fuels and produces more toxic emissions than the entire world transportation sector. note that almost every article i cite states that money and tradition are the only reasons people don’t agree with this. that’s kind of like money and tradition being the reasons people didn’t want to stop having slaves. there is no logical basis. just so you don’t think i’m ‘biased’ because i’m vegan, also note that several of the articles claim people can still eat meat, just a lot less (that’s how we got this problem in the first place, but the point is that meat eaters are addressing the problem, not peta). they suggest pasture-raised alternatives for increased sustainability. while this would in theory cause fewer emissions due to the more natural diet (also a myth), it requires even more extreme amounts of water and land and is therefore also unsustainable. tl;dr: your hummer is more environmentally friendly than a steak.
