While it may be true that technological advances can improve our capacity for food production and our ability to house more people in compact spaces, at some point we will surely reach a limit. The earth can only hold so many people without serious damage to our habitat and to biodiversity. How do we put a stop to the relentless growth? The key, in my view, lies in educating women – which causes them to want fewer children. The sooner we are able to do this, the sooner we will have a less populated world.
