Um, when nations reach a post-industrial stage, as most of the West is now in, birthrates decline drastically. This is why almost all Western nations have an ageing population.Lentern said:And why will it plateua? People are going to stop having children? Australia is going to become yucky so it won't be such a popular migrant destination? We going to line the shores with dingo's and bogans to scare off the migrants? I know it would be best if Australia had less or more people from a sustaining natural resources perspective but how does that fit in as practical with the rest of the worlds population growth?
Nations like Japan, others I can't recall atm, are actually facing a declining population.
Without immigration, Australia's population would be declining too, birthrates have dropped that much. Birthrates are below population renewal levels, less than 2.0 children per couple.
Even with 100'000 people immigrating to Australia per year, population growth is only 0.05%.
So plateauing is very much on the cards for much of Europe, Japan, others.
Looking at it philosophically, global population has to plateau or decline at some point. You can't have exponential global population growth for an infinite timeframe. Even with the best technology and management, you reach a maximum carrying capacity of the land, something the best estimates say we've already drastically exceeded in Australia.
You haven't specified for what purpose exactly Australia's population should be grown, other than some vague notion of being a world power, which begs the question, why be a world power? You've admitted that our individual quality of life would drop, so why do it? We don't owe the rest of the worlds population access to a share of our quality of life.
