A study and computer program in the 1970's, (World Dynamics), by the late Jay Forrester of MIT identified 2050ce as a tipping point where human population outstrips living resources. Given our ability to use/invent technology and to discover additional resources, that 2050ce date may actually be much later. Conversely, given our unique primate driven proclivity for violence, greed, and rapaciousness we may not make it to that 2050ce date. I just don't know. If I could accurately foresee even 50 years into the future, I would pawn, borrow and cash-in every asset and make investments. (Thus, with my expected future fortune, I might be able to be insulated from any chaos, the taxman notwithstanding).
