A Bad Cold?

Scientists have now decided they've discovered that Mars once had water. Perhaps they're trying to equate it to Earth and the eventual demise of our own planet. Of course it could happen. This planet has been, like most others in the solar system, in a constant state of flux from its inception. Ice Ages, Meltdowns... none of which were caused by human intervention, or technology have been happening throughout the milleniums. Nothing science can do will stop it. As a favorite George Carlin skit once proclaimed... humans are like a virus. Earth will shake us off like a bad cold and continue on it's path.
