Oh why! Oh why would we want to spend good money to go to other planets and to study the stars. We have too many chores to do here at home! Global warming, poverty, pollution, crime, drugs, it never ends. How could a reasonable person decide to go to Mars? How could a reasonable person decide to have a baby?
But people do want children, and people do want to explore. Despite the drawbacks, we must carry these burdens.
I guess we're only human!
