I don't like this argument that it's just the rich screwing us over. Ya, they're dickbags with no small responsibility for perpetuating our current situation and their insane lifestyles. But all of us need to use less junk, travel less, and eat a whole lot less meat.
I know so many people who will talk about the environment, but will still think nothing of hopping on a plane for the most frivolous of reasons. Won't even consider public transportation. Eats meat every day.
Ya the oligarchy is fucking us over big time. But that doesn't absolve you of any sort of personal responsibility. Reduce, reuse, recycle. And plant a garden while your at it!
