The global food supply is supported by fossil fuel based fertilisers. What happens when the gas and oil starts to run out?
Freewill running out of gas shouldn't be a major concern for people who live now, or even WILL live, in this millennium as we undoubtedly have enough gas available now as 2C contingent resources for this millennium. But I am tipping we will, Freewill, have developed renewable energy and fertiliser alternatives to gas well before 3000AD, it is the overpopulating of Earth re other resources like water that concerns me.
