How often do you think about your carbon footprint?

This article, I am the population problem, from grist.org puts into perspective a bit. And no, it's not candy-coated for you with vague scientific terms so you feel distanced from it. It's short and it is what it is: true.

Conscientious people try to limit that consumption, of course. I'm one of them. I get around largely by bus and on foot, eat low on the food chain, buy used rather than new, keep the heat low, rein in my gadget lust.

Towards the end she begins talking about GINK (Green inclinations, no kids), a pretty self-explanatory movement about reducing your impact on the Earth by simply not having children. I know it's strange and counter-cultural  idea especially in our get-married-have-children society (which I by no means think is wrong). But isn't the fact that we find it such a bizarre decision confirm that we, as a society, are hesitant to accept those we make that choice?
