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

We can both prevent asteroid impacts and address climate change. It's not either-or.

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

There's no accepted global policy on what to do about asteroid impacts.

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.

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

For the first time in history, we have the chance to change the path of a celestial body. Let's realize what we're talking about here. We would be slightly changing the mechanics of our solar system to enhance our survival. That is gigantic!
