We not only need to train people, we also need to develop deflection technologies.

While we didn't know the dinosaurs personally, we do know that they were wiped out by an asteroid impact.

You almost wish you could turn off the COMM and just appreciate the deafening quiet.

By preventing dangerous asteroid strikes, we can save millions of people, or even our entire species. And, as human beings, we can take responsibility for preserving this amazing evolutionary experiment of which we and all life on Earth are a part.

In the short term, some deadly virus might be more important, but in the long run there is hardly anything more important than asteroids.
