The irony of scientific progress is that in solving human problems it creates problems that are not humanly soluble. Science has given humans a kind of power over the natural world achieved by no other animal. It has not given humans the ability to remodel the planet according to their wishes. The Earth is not a clock that can be wound up and stopped at will. A living system, the planet will surely rebalance itself. It will do so, however, without any regard for humans.
