BBC Asks "Is an ageing population a good thing?"

If it is comfortable and satisfying, long life is a great thing. After all, we only get a little time out of eternity. But of course having more people alive also further strains our planet's resources, and eventually, as Kurt Vonnegut pointed out in "Tomorrow and Tomorrow and Tomorrow", tempers as well. So if we're going to stick around a long time, we should either think about how to extend resources without overtaxing our planet any further, about having fewer children, or colonizing the moon.
