I believe we're in a really unique point in human history. In many respects nothing like this has ever happened before on the planet Earth , that we have a very unique life form, namely human beings, who have the capacity to develop and use technology and multiply both the good as well as the negative impact associated with it. The population of human beings has absolutely exploded over the last 100 years at a pace that's never happened before as far as we could tell in the history of the planet. So, when I was born in the early 1950s, there were perhaps 2 billion people in the world. Now there's 6,5 billion. Somewhere around the time of the American revolution we reached 1 billion. And it took all of human history up to that point to get to 1 billion. So in one human life time, my own, we've seen our population grow from 2 to 6,5 billion. If I live to be a ripe old age, I could see 8 billion people on the planet. In one human life time. Plus multiply those people times the impact that they can have through technology, is unprecedented. Nothing like that's ever happened before.So the choices that we make about how we engage in development... The truth is, most that we consider to be capitalism and commerce, at least in a modern sense and quotes, has really included only roughly a billion of those 6,5 billion. If we were to imagine playing out the other 5,5 billion, not to mention getting out to 8 billion along similar lines, you can imagine the consequences.So we are truly at a crossroad in terms of figuring out first of all how do we include the entire human community of 6,5 billion in the capitalist dream, and how do we do so in a way that doesn't destroy the planet in the process. That's the challenge we face.
