Overpopulation is a fallacy.
Rubbish. There's only so much energy to go around without "overconsumption".
We need to lose a couple of billion people and everything will be fine.
Poppycock...
Thomas Malthus, who famously observed "Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical rate." In other words, population goes up faster than what's needed to feed the population, and so excess population is a threat to everyone and is the primary cause of famine, poverty, and war.
To countless people, this isn't just common sense, it's considered very wise. Yet I suspect that in all of human history, no prophecy has been more consistently uttered that has been more consistently wrong. And it seems ultimately based on one false notion: that human beings produce nothing, and only consume. "One more mouth to feed is one more mouth to feed," as the saying goes.
In free societies--even just relatively free societies--a human being is not "one more mouth to feed." A human being is one more set of hands and eyes and feet to work and produce. Most important of all, one more human being is one more brain to help solve problems.
Look throughout the free world, which includes even only somewhat free places like Bangladesh, or Venezuela, or Hong Kong: invariably, wherever population densities are highest, you will find that property values are highest, standards of living are highest, standards of medical care are highest, and education levels are highest. And in any reasonably free nation, you will find that the areas with the lowest population density will be those with the lowest levels of education, the highest rates of unemployment, the highest levels of poverty, and the lowest standards of living.
There are only two exceptions I can think of. Occasionally, government action will create artificial zones of economic activity in areas that would otherwise be impoverished. In the U.S. for example, some very low population density areas in places like Arkansas, South Dakota, Wyoming, etc. benefit substantially by money brought in from military bases the government has established there. So amongst other things, the government is siphoning money into an otherwise low-population area and creating an artificial economy. Even then, where do they get most of the money? From the high population zones, of course. Becuase the high population zones are where most of the money comes from.
The only other exception you'll find to this rule is that occasionally you'll find that the extremely wealthy will live in low-population communities, in enormous houses on even more enormous tracts of land. But even then, you will usually find that they are living within a reasonably short commute to a high population density area. Why? Because that's where most economic activity takes place.
Fairly consistently, over the last several thousand years, the world population has steadily expanded while the Malthusians tried to tell us that this couldn't possibly go on forever. Today the world population is the highest it's ever been. Yet today, the world population is also better fed on average than it was in the past. Indeed, for as long as we've been able to measure these things, human beings have been producting more and more food on less and less land all the time. Not just in relative terms (i.e. less acres per person), but in absolute terms: as the total number of people goes up, the total number of acres of land needed to feed them goes down. And once people grow wealthy enough, they begin to worry about things like clean air, clean water, and species and forest preservation, which they can only do if they've got enough freedom and enough people to make an economy that grows. In North America today, the air and water are cleaner today than they were 100 years ago, and there's more forested land than there was 100 years ago too. There is no reason we should not expect that trend to continue worldwide so long as freedom of opportunity continues to expand.
In a free society, human beings are resources, not liabilities. Indeed, the free world is increasingly facing the exact opposite of an overpopulation threat: we're increasingly worried that young people aren't having enough kids to propagate the next generation.
