Space Threat?

Daniel thought I would write something about the threat from space, that is, the threat that an asteroid would hit Earth and devastate large parts of it. It may destroy civilisation as we know it, though this is rather unlikely. It was probably a huge asteroid that killed the dinosaurs 65 million years ago. An asteroid that size would destroy civilisation, but how likely is it that we are hit by it in the near future? Daniel is concerned, though. He says that humanity has the opportunity to take action against the threat, so why not do that? It would be costly, but may be worth it. He has a point. Well, I am not part of humanity (being a dog is better, in my mind), but I can write about the threat in my blog, at least.
