Mankind erased by 2/3 in 40 years Hello, Banshee! Where did you get the tip that mankind will be wiped by 2/3 in 40 years from now? Maybe from the same people that made Paul Ehrlich predict that a huge famine was going to kill more than half the Earth´s population (back in 1968) when he said in his book "The Population Bomb" that the United States would reduce its population to less than 150 million in ten years. He said "The fight against starvation is lost". It seems that he didn´t know about Borlaug's Green Revolution, the advances in biotechnology, genetically modified crops, decreasing costs in new technologies that made natural resources more available to human beings (especially in developing and poor countries). Those 40 years prophesized surely are a guarantee that most of us won´t be here to see if it came true. Try to make a more shorter term prediction that could be really useful.
