Also why were people banging on about how theres far too many people on earth

Malthus came up with the idea of over population and it became the hobby horse for the UN/Globalists. Kind of like Global Warming. Lots of noise and great fear mongering but few facts. I realised that the world population numbers were fictional decades ago. There is a wonderful book out called The Empty Planet. It discusses the huge drop in birth rate around the world. Few nations are even at replacement levels let alone population growth.
