Hmmm... nature lacks some significant features: such as sulfuric acid vents poring millions of tons of caustic chemicals into the water supply. Natural sub surface oil/tar pits polluting underground rivers/surface streams with pitch black crude or toxic heavy metals. Pyroclastic volcanoes venting poison gas into the atmosphere by the metric ton. Super massive coal fires ignited by magma displacement, burning entire mountains hollow. Free range forest and grass fires killing and burning virtually everything in its path, for hundreds of square miles. And of course the oceans themselves, warming and cooling, releasing 99% of the carbon present in our atmosphere...





Nature is highly destructive, and fully capable of falling well out of balance all on its own, and without warning, as its totally unmoderated. Hence the past 5 mass extinction periods. Note: Where there is five, there surly will be a sixth...



Thus our only chance in hell, is to advance enough to either prevent it, or survive it...







So really... maybe nature should be holding the gun.
