I'm sure many people know that, at the current rate we are using Earth's resources, humanity wouldn't last very long. We need more resources, more land, and a new place to expand. A mission to Mars is a necessary solution to these complicated problems. It's a place needed to sustain life.
I believe that the public supports a mission to Mars. I think most would agree that we are using up Earth's resources and the climate is changing greatly. We might exhaust all the resources on this planet, so exploration to Mars or another planet might be needed in order to sustain human life.
