We will infect Mars (Score 1)

Mars a different kind of environment, maybe there is life on there that we can't see? We probably brought some bacteria up there with the rover that's currently spreading and infecting mars with earth diseases ... the current life on mars is going to get infected and grow cancer, the Mars diseases are going to spread and will eventually infect the rover .... when the rover comes back to earth The Mars Disease is going to spread the earth and make our planet look like Mars. -ko
