"Trying" to go to Mars will be the STUPIDEST thing America can do! Folks, we just cannot afford, at this time in our History, to try to go to Mars. First, the Astronauts would not survive. How on earth could they carry enough food, water, co2 filters, a waste disposal system for what, maybe 2 years worth? And the costs involved. Doesn't anyonbe see that we are practically bankrupt? And really. Why go? There isn't anything there and if there was what are we going to do? Load it up and bring it back? We cannot even live in Peace here on Earth. Of course, as far as environments go, we probably couldn't mess up Mars because it doesn't have one. No rainforests to destroy, no rivers to pollute. Good gosh. Has mankind lost its mind? Please, let's put our resources to use here on our home planet, Earth.
