What If... (Evolution) It just occurred to me - our planet is way overpopulated, and life is frankly unsustainable under current conditions. Could it be that this is truly a massive evolutionary change where the planet kills off 1/3+ of the population via obesity? The weak "genetics" get culled out so that only the more hearty are around? This man-made caloric-asteroid-like event could be a natural way for us to (ironically) thin the herd. I've got to smoke more of this stuff...it's awesome!
