Neither government or business likes declining population numbers, or a declining tax payer base:
''In France and the Scandinavian countries, which have some of the
highest fertility rates in Europe, parents get lots of government help. A French maman has at least 16 weeks of mandatory, paid maternity leave, as well as guaranteed job security and—if she has a third child—a monthly stipend of up to 1,000 euros for a year. In Norway, women are entitled to 10 months at their full salary or a year at 80 percent. Because these policies have been in place for decades, the countries' fertility rates are approaching 2.1, roughly the point where a population can sustain itself without immigration. Other nations are emulating this approach: Spain now offers a 2,500 euro bonus for every baby born. South Korea, which has one of the world's lowest fertility rates, shells out $3,000 per couple for in-vitro fertilization. And in Germany, where women have an average of 1.3 babies, Angela Merkel proposed up to 1,800 euros a month for stay-at-home parents, and more day-care centers to improve the public image of working moms—who have long been dubbed Rabenmütter, or "raven mothers." (Countries plan these financial incentives carefully to avoid drawing in too many poor parents—and creating a bigger lower class.)''
So you are saying that despite the best efforts of governments in Europe, they can't generate a population explosion even if they want to?
I am glad you agree that overpopulation is a non-issue.
I'm saying that our system, government and business, does not appear to tolerate stagnation. A state of ''stagnation'' is interpreted when population figures stabilize or fall, along with consumer and tax payer base.
I personally see the world as being overpopulated. It passed my personal tolerance limit decades ago. Not that we haven't the means to provide, but personal space, congestion, amenity.
I know that overcrowding is not necessarily a sign of overpopulation, but as population grows, so do our towns and cities. Where once was bush is now farmland, where once was farmland is now suburbs, MacDonalds, crowded shoppings centres, freeways, congested roads and footpaths.
Yes, this can decentralized, but this is spreading more of the same to areas that are now relatively pristine, that have a little space, a bit of breathing room, that have a relatively natural environment.
I think that we need to consider the natural world more and stop spreading ever outwards.
There are still plenty of places with thousands of square km without a single person. If overcrowding is an issue for you, you can avoid it just as easily with 10 billion people on the planet as you could with 10 million; you can't possibly detect the difference between being a thousand miles from the nearest inhabited place, and being ten thousand miles from it. Either way, you would only see another person very, very infrequently, unless you chose to do otherwise.
If Cairns gets too big, you can move to any of a huge number of smaller places; just head West - there is more empty space there than you could ever explore. There are lots of places that can only be reached by helicopter, or after many weeks on foot, and that have never even been seen by anybody except a handful of Aborigines; places not a single person has been in the last century are plentiful, as long as you don't expect there to be any roads or tracks to help you get to them.
Crowding is an artefact of people choosing to live close to other people, for mutual benefit. There are few jobs in the bush; but it would be perfectly possible to live out there as a hermit, if you didn't want the benefits of civilisation. If you want the benefits of living in a town, then you have to tolerate the fact that lots of other people will be there too; that has nothing to do with overpopulation though.
I like the idea of living far away from crowds of strangers myself; I don't do so, because I like the amenities of urban life even more. But even with 10 billion people on the planet, the option would still be there to avoid all of them. The populations of the small towns in western Queensland has been falling for over a century, as people choose to concentrate themselves in a small number of larger centres. They can do this because communications have improved; miners can FIFO rather than living near the mines; cattle can be mustered by helicopter, quad-bike or 4WD rather than on horseback. Urban growth in your part of the world is largely the result of extra-urban population decline; the people are moving from places like Childers, Almaden, Forsayth etc. to Brisbane, Townsville, and Cairns.
Far from 'spreading ever outwards', the population of Australia is continuing the trend of a century and a half, and concentrating in fewer, larger cities and towns. Brisbane is spreading outwards, but that spread is fuelled by the contraction and abandonment of thousands of stations, tiny settlements, and small townships. Population density in the cities is rising, but in the bush they are falling, despite overall increases in the population of the state as a whole.
