Population is projected to reach a peak and then it will crash. They'll be singing a different tune when that happens.
"People have been worrying about the world’s pending overpopulation for more than two centuries. Robert Thomas Malthus sounded the alarm in 1797 with “An Essay on the Principles of the Population,” which predicted mass starvation and went on to influence the likes of Charles Darwin and Margaret Sanger. Paul Ehrlich’s 1968 book, “The Population Bomb,” forecast a similar fate; if the population kept rising unchecked, Earth’s resources would buckle. Many of today’s environmental thinkers, such as broadcaster (and “Planet Earth” narrator) David Attenborough, have called for drastic measures to limit the planet’s population before it’s too late.
But according to the veteran environmental writer Fred Pearce, they’re all wrong. In his latest book “The Coming Population Crash: And Our Planet’s Surprising Future,” Pearce argues that the world’s population is peaking. In the next century, we’re heading not for exponential growth, but a slow, steady decline. This, he claims, has the potential to massively change both our society and our planet: Children will become a rare sight, patriarchal thinking will fall by the wayside, and middle-aged culture will replace our predominant youth culture. Furthermore, Pearce explains, the population bust could be the end of our environmental woes. Fewer people making better choices about consumption could lead to a greener, healthier planet.
Well, is it true?
Global environmental problems are not, and will not, be mainly a problem of overbreeding Indians or Africans. First, their birthrates are coming down fast, with Indian women, for instance, having fewer than three children on average today; and even African women have falling fertility. And secondly, because overbreeding — in the sense of women having more than replacement levels of children — is almost entirely in countries with a very low per-capita footprint on the planet. For instance, the carbon emissions of one American is the same as that of 20 Indians, 30 Pakistanis, 40 Nigerians and 250 Ethiopians. If, as economists suggest, the world economy will grow by 400 percent by 2050, then no more than a tenth of that will be a result of population growth. The issue is consumption, and that puts the onus right back on the conspicuous consumers to do something about their economic systems, not least before more developing countries follow the same model."

It's always prudent to be aware of alternative ways of looking at the situation.
