MANN: “That’s absolutely right. And we’re using more of that space now for agriculture, for other human purposes, so literally the amount of land available to us is shrinking at a time when our global population is increasing. It’s at about 7.5 billion people, likely to hit 9 billion later this century. We’re talking about less food, less water and less space for a growing global population and that’s a recipe for a disaster, a disaster that is unfolding slowly in real-time.”
