Survival of our species/Intro

There really couldn't be anything more important than this. Currently we have all our eggs in one basket. We live on one planet and there are various threats, both manmade and natural, that could destroy our current civilisation and even wipe us out entirely. To put it bluntly we are vulnerable. Asteroids, virulent disease, global war with advanced weapons. All are possible and we must protect ourselves.

We've come a long way and gained a lot of culture and knowledge - it would be a shame to lose it at a time when we have the technology to do something about it. It's also about not messing things up for future generations. It is not just about surviving but having good prospects, opportunities and a nice environment to live in.
