Sdaji - I think you misunderstood the intent of my post.
Humans will find a way to increase mineral extraction, agricultural production and find large sources of offshore oil. Consequently we continue to grow our population which has not peaked (unfortunately). The carrying capacity of the planet can not easily be measured so maybe we already have too many people, but I don't have time to argue this mother of all questions.
Popular science leads us to think we are in a downward spiral. Is the glass half full or half empty? - are we slowly recovering from years of bad decision making or are we making more bad decisions?
A high standard of living (including access to education and access to conserved areas etc) means we identify better with the environment as we have more spare time to think about it IMHO.
As Australians we are spoilt by employment levels and hence the migration magnetism. What we have on our side is a small population, hence the skills shortage and a demand for people like you and me.
Recycling - the reason I threw this in is that our wasteful habits as a race are problematic and this is one solution for keeeping the human race sustained. If we reuse and recycle the things we consume we lessen our impact.
So, I was just being the devils advocate and if you take it all too seriously then you may have peaked too early
, there is plenty more that can be done in a practical sense.
