Is Life Sustainable on Mars?

It will be in the future!  Scientists are working around the clock in hope of one day making life possible on Mars.  Since Mars's atmosphere is too poisonous for life to occur, scientists are looking into changing it to one similar to ours.  To understand how this can be done we turn to the scientists and researchers for answers.  This can be attained through sending various probes to Mars from a time frame of one hundred years.  Over the period, tiny craft like probes would land on the surface of Mars and release these gases into the air: carbon, hydrogen, nitrogen, oxygen, phosporous, sulfur, chlorine, and fluorine.  After this process is completed, early vegetations like algae would form.  Maybe in the future pine trees would grow on the surface of Mars.  It has been estimated that after a few generations of humans reproducing on Mars that mutation will occur.  Scientists speculate that an average human being would be two feet taller on Mars for the reason that Mars have one third the gravity of Earth.
