The world is over-populated. Nearly 6.5 billion is a staggering number of people. Why then are we focusing on curing cancer or saving starving children from dying in regions of the world that clearly can't support them. What we really need is not more old or young, it's a model for how we could possibly live a sustainable life-style. Until we understand how to manage our limited resources, our hubris will just keep making monkeys out of us. A space-ship might help too.
