The Martian

I watched the movie "The Martian" and I'm going to write a little report on it. (SPOILER)

   The three things that you would need to focus on for you survival are water, breathable air, and food. Mark Watney who is the main character solves these problems by - Water: He burns the fuel for the rocket which creates water by making the hydrogen combine with the oxygen in the air. Breathable air, and Food: Mark plants potatoes for food but that also creates oxygen by breathing in carbon dioxide and releasing oxygen.

   Earth naturally provides drinkable water in the form of rivers, streams, lakes, and ponds. Earth provides Food in many many different forms from plants to meats, and also provides breathable air because the atmosphere traps in the oxygen and the plants convert carbon dioxide into oxygen.If humans actually went to mars then they would have to overcome these simple obstacles to simply survive.
