Understanding the Mission to Mars
[1] The Martian was a movie that made traveling to Mars seem much more possible than it has seemed before. The movie reveals many of the hardships and unexpected problems that could develop. In addition, the dangers and expenses of such a trip make many people doubt that humans.should go to Mars. Despite the dangers, more people are starting to think that taking on this challenge and going to Mars are worthwhile and beneficial to mankind.
[2] The first reason a trip to Mars might be a good idea is that the Earth is experiencing many threats to its wellbeing, and humans may need a new home. The human population is growing so fast that Earth is starting to be stressed. In many places, there is not enough water for people to drink.Even places that never had to worry about a water shortage are starting to control the amount of water they use. People are starting to fight each other for control of water. There are also many places in the world where crops don't grow well. This has caused food shortages, and people are suffering. Climate change adds to the stress on Earth. Warmer weather and rising sea levels have made storms very violent. These problems give the sense that the planet will not provide for billions of people forever, and they may need to go somewhere else.

[3] A need for other resources also gives humans a reason to go to Mars. Many electronics, including smart phones, are made with rare minerals that are hard to find on Earth. If man cannot find these minerals, there will be unrest and maybe even violence. Mars might have some of these, but it also will have new resources that man doesn't even know about. Just like the rain forest has produced secret medical cures, Mars must have medical benefits humans cannot imagine. Also, man has been trying to find alternate fuel sources for many decades. The Earth will run out of natural gas.goal, and oil, and humans will have to find other sources of energy. Moyo (2012) explains that "arable land, potable water, energy and minerals are finite, scarce and rapidly depleting on Earth. Finding new resources will allow humans to continue developing all kinds of products for food, health,and technology.
