is there enough land for them? Well, throughout the world, if we look at the lights at night, the one thing that's misleading is that, visually, it looks like most of the world is already built out. So let me show you why that's wrong. Take this representation of all of the land. Turn it into a square that stands for all the arable land on Earth. And let these dots represent the land that's already taken up by the cities that three billion people now live in. If you move the dots down to the bottom of the rectangle you can see that the cities for the existing three billion urban residents take up only three percent of the arable land on earth.
