[00:00:00]Let's check it out. So, Stephen, you've said publicly that you want us to be a multilanet species, and who could argue that? I'm with you there. However, I have one mild rebuttal because you defend that argument by saying something bad could happen here on Earth, an asteroid, that's runaway virus, rendering us all extinct, and if we exist only on one planet, that's the end of the human species. I get that. Here's my mild rebuttal.

[00:00:29]Isn't it easier to deflect an asteroid?

[00:00:32]Easier to find a super serum that will combat any deadly virus than it is to terraform Mars and ship a billion people there.

[00:00:43]>> Collision with an asteroid is one of the least of the dangers we now face.

[00:00:50]>> The last collision was 70 million years ago.

[00:00:54]Nuclear war, climate change, and pollution are now much greater threats.

[00:01:01]Of course, it would be impossible to move the population of the Earth to a new planet. But if we can establish independent self- sustaining colonies in space, it would ensure the survival of the human race in the event of a disaster on Earth.

[00:01:19]Leaving earth will also give us a new perspective and cause us to look outwards rather than inwards.
