Over 100 billion people have lived on our planet.
Just 622 have been to space.
Just 12 have set foot on another celestial object, our barren moon.
Not a single human has been to another planet.
We know of no other planet that can sustain human life.
Why is it so damn hard to get people to care about protecting the only home we've ever had and the only place we can live?
