Or, rather, we needed to about 50 years ago. It's too late now.
I hope you are wrong about it being too late, but it certainly looks like we are rushing blithely towards a cliff atm
You are dead right about education though. That has to be our "last, best, hope". But it needs to be the sort of education that changes unhelpful behaviours like the public campaigns 50 odd years ago [over here anyhow] that made it social unacceptable to go out and get drunk and than drive home. Does drink driving still happen, hells yes; but overall social attitudes towards it have changed markedly.
The optimist in me says it never too late, the pessimist says that it is so far past late that it really isn't funny, the realist says that the longer it is before we look seriously at the underlying causes of things like poverty and ecological degredation the more people are going to be damaged in the process of trying to survive our profligate history.
@Dok Howl: Btw I wasn't saying that what you said about poverty as a driver for population growth was wrong, just that poverty in turn is being driven by other factors which are of a higher order, and that you can't "fix" poverty without addressing those underlying structural problems/issues, I should have been clearer on that.
