Is There a Risk of an Asteroid?

We try to make people better off globally, so that we decrease the probability of a large scale cal and political and economic instability. We know one risk, which is being hit by an asteroid that could wipe out the the earth yet. So you can actually see that we put a price on how much are we willing to do this? That's just one place where we have a very clear example that we say we care somewhat for the future. But we don't care about it entirely. And that's exactly what the models show us.
