The Short Answer

Because as Heinlein said: > The Earth is just too small and fragile a basket for the human race to keep all its eggs in. or as Randall Munroe observed: > The universe is probably littered with the one-planet graves of cultures which made the sensible economic decision that there's no good reason to go into space–each discovered, studied, and remembered by the ones who made the irrational decision. There is nothing we particularly need on Mars. There is no good reason to live on Mars, but if you looked at it cold and calculating enough there is also no good reason to live on Earth. We have to ways we can go from here. Humanity can stay on earth and die with its planet at some point in the future or we can go out there and spread ourselves among the stars. Mars is the first step on the second path, we don't know were it will lead and what benefits it will bring us, but the other one is literally a dead end.
