The Problem With Overpopulation and Climate Change
We waste nearly 40% of the food that's produced and a similar portion of the energy that's created is wasted as well. There are 400 million farmers in the world who are producing purely for the waste tip. We can't go on treating our farms as mines any longer. And then you don't have to do mining any longer, because it's already there in the waste stream. I want everyone to pledge themselves to sign a treaty with an earth system where people can inhabit successfully their children and grandchildren.
