An asteroid can literally destroy 80 or 90 percent of the species that are alive on Earth. These are big events. I mean, this is called extinction.

Anytime we can save lives or prevent the destruction of property, we should do it.

If we do our homework right, never again should an asteroid that can do damage on the ground impact the Earth. We're living in a time-with our technology-we have the capability to eliminate that major shaper of evolution . . . the evolution of life on this planet.

It would take an extremely large spacecraft to deflect a large asteroid that would be headed directly for the Earth.

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

Asteroids have hit the Earth millions of times. We can see them as shooting stars every night. When they get bigger, things get complicated. It is only a matter of time until a big one hits us. And since we can do something about it, we should.

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