People on the earth need oxygen to breathe. There is almost no oxygen on Mars. Living on Mars would be
like living on a very high mountain. There would be little air. It might be 50 degrees above zero at noon and 100
degrees below zero at night. We know that Mars has carbon. Through a telescope, Mars looks red. In some
places, it seems gray. At times the gray turns gray-green, then brown, then gray again. The gray-green may be
a kind of plant color which changes with the seasons.
Life is expected on Mars by scientists, because there are distinct seasons on the planet's surface. This
condition might support plants. However, some researches find if Mars had life, it must have been a long time

planet's environment has changed. Mars is not a pleasant place for any form of life.
