I didn't say we should be billions more. I said we could if we cared about our environment. I simply believe it's more effective to explain the danger we face and get people to really care, than to curb population growth. The first reason is that it takes more energy to fight the desire to reproduce than to get people to live responsibly (at least not more than our environment can bear). Moreover, if you somehow get people to reproduce less than they desire (without causing to much frustration), you'll still have to educate them about the sustainability issues (aka our way of life). Why not directly address the way of life challenge, then? People don't want many children when they know what's coming (your first child's future is in jeopardy, let's have more!). It's no coincidence that those who have/want the most children are the least aware of the biodiversity/climate problem.
