We are not over populated for the resources lol.
The only thing that will be a problem is if it stops raining and water is scarce we are fkd, if that happens we won't be affected as much as the other huge population centres around the world. Who knows if that is what is going to happen, what we do know is humans adapt, we have done it before and we will do it agian. We just might have to trade in our exotics to pay for water
Couple of quotes from one submission to the Standing Committee on Ageing in 2002, the situation has gotten worse since then.http://www.aph.gov.au/house/committee/ageing/strategies/subs/sub55.pdf
Does Australia have the resources to sustain a population of this size? There is a large
and growing body of scientific evidence to support a view that, on the basis of our
present way of life, Australia is already overpopulated.
We live in a land of naturally poor soils, which have been further degraded throughignorance
and over-exploitation. One of these problems alone - increasing salinity,
particularly in Western Australia and the Murray Darling basin - provides a major
threat to the productivity of much of the country’s agricultural lands and to regional
social assets such as roads and buildings.
In Perth, the level of the aquifer which supplies much
of its water is sinking at an alarming rate, and a recent study has found that Perth will
run out of sustainable natural water resources by 2015 if nothing is done to slow
Bringing in more people to Australia is up there with bringing in Cane Toads to Qld and adding Carp to our river systems.
Why make the problem worse and say "But yeah, we adapted in the past, we'll adapt again". Why not slow the problem before it happens?
