From your response, it sounds like you're frustrated about the state of affairs. However, you're not defining a single concrete action, which makes me confused because my question was: What do you propose that we do?

A first step, at the very least, would be helpful.

But then, it sounds like you do not believe in a favourable outcome. So why do you bother? Why not just make peace with it, if you truly believe nothing can be done.

I don't share you belief. I think that, if given the chance, nature is more than capable of turning things around. I think that we are far from the tipping point.

Also, most young couples I know are choosing not to have children - maybe intuitively they just know we need to slow down population growth. Have you noticed that?
