Oh yes we will, and it probably won't be all that long from now. We are changing the climate in ways that will bring adversity, in great quantities, to all of us. Some sooner than others, and some worse than others, but we're all going to get it eventually. We also have the possibility, as a species, of extincting ourselves with our nuclear weapons. One of the basic problems with Planet Earth is that there are too many humans on it. There are currently 7.4 billion of us, and the planet can't sustain that many, at least not with the life style the "developed" world enjoys. Many scientists have made estimates of how many people can live sustainably on the Earth; most estimates run in the half billion to 2 billion range, although I have seen estimates as low as 100 million.chrisuk wrote:those of us in the affluent West have no idea of adversity, and never will
Humanity (and other species) are like the yeast in a wine bottle. They create an environment that eventually kills them. Or, in the absence of predators, they overpopulate and die off, as was shown on St. Matthew Island with the introduction of reindeer in 1944:
