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

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.

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

I am interested in climate change and other topics too. But this thing is so huge, in the worst case we are talking about the end of our civilization.

You see the Earth as a bright blue and white Christmas tree ornament in the black sky. It's so small and so fragile - you realize that on that small spot is everything that means everything to you; all of history and art and death and birth and love.
