It's not just about food. Even if it were just about food and even if we could theoretically feed everyone with our lands now, we are *also* ruining our farmlands in the long-term for higher short-term yields (which the site seems to applaud for the hey look, more food idea!). Also, it's based on stuff like this:I'll point to the highlighted word and point to what forum we're on as to the problem with that paragraph.Thanks to continuing increases in crop yields, the world's farmers are harvesting hundreds of millions of tons more grain each year on tens of millions acres less land than they did in the 1970s and '80s. For instance, according to USDA figures, the world was producing 1.9 million metric tons of grain from 579.1 hectares of land (a hectare is 2.47 acres) in 1976. In 2004, we got 3.1 million metric tons of grain from only 517.9 hectares of land. This is quite a jump.
Population will decrease by 2045? That's a bit too late.
Edit: Actually I poked around some more. The overpopulationisamyth site claims we'll peak at 2045 at 8 billion people. Latest report is 10 billion by 2100 from the UN. http://esa.un.org/wpp/Other-Informat...se_WPP2010.pdf In fact, the 8 billion peak figure is from their *low* projection and is now actually expected to happen in 2050.
So it looks like they're using some old data.
