The kids thing is curious. Maybe I'm just selfish, but I have no kids and my thinking is, well, I'm not that worried about how the earth will be after I die. Meanwhile the folks with kids are the ones who produced giant resource consumers and ironically -- because they want to ensure their kids' wellbeing -- are the ones most worried about the planet's survival.

Obviously the answer is for me to care about society (on a global level), but it's hard to do so without skin in the game. And considering it feels like others don't care or are still very wasteful... why should I be pious?
