Maarten: Bevolkingsgroei ligt ten grondslag aan de steeds groter wordende vraag naar natuurlijke hulpbronnen, niet alleen energie, maar ook naar mineralen, water en landbouwgrond. Heeft Paul Gilding wellicht goede ideeen om de bevolkingsgroei aan te pakken en is hij voor het opzij zetten van de rechten van het gezin ten aanzien van het krijgen van kinderen, zoals in China gebeurt?
Paul Gilding: Population growth is indeed part of the problem, but I think people overstate how important it is. When you look at the science, between now and 2050 the population will increase by about 30 or 40 percent. But if we carry on growing the economy, the economy will grow by 300 or 400 percent. So what that says to me is that population matters, because it makes the problem worse by one thirth, but consumption matters more, because it makes the problem worse by 300 percent. It has a much bigger impact. However, we tend to focus on population as an issue, because it makes us feel better: it is not us, it is them. It is just more people keep having children, that is the problem.
But I am not saying population doesn’t matter at all. And there are plenty of things we can do about population grwoth. In developing countries people are educating other people to reduce the need for having more children, of course that is a good thing. But in terms of the bigger problem, the impact is just too small. When we had the chance in the 1960, the continuing population growth would have been a really good thing to focus on. Now it is simply to late to be able to really change things here.
No, I don’t belief in one-child policies, because that would require a dictactorship and I don’t think that is a good model for society. But the things we need to do is to educate people, making peoples life better so they don’t need to have so many people to support themselves. Those are the things we should be doing. But than you still come back to the issue of efficiency, because the issue is not the population but this exponential economic growth.
