[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.

[4] Another reason humans want to travel to Mars is a sense of exploration and discovery. Humans have traveled to far-away lands for centuries in search of other life. They did this even when they traveled by foot because they wanted to find resources, food, or other cultures. Today, this interest in travel is why the world has become so small. Now, people all over the world share languages, companies, investments, and relationships. It's natural for humans to want to continue exploring and expanding their lives. There's nowhere else on Earth to explore, so the closest planet is the new frontier. Furthermore, humans have always wondered if they were the only intelligent species. The search for alien life is a big motivator for many people interested in Mars. There's even a theory that "a Mars rock with life in it" could have landed on Earth and "kicked off terrestrial life (Orwig).This theory can only be tested if life is found on Mars (Orwig). Curiosity about what humans will find on Mars keeps them interested in the new planet.

[5] One issue that needs to be settled is who will make the trip to Mars. One option would be a multi-national team because there has long been a space race on Earth. This competition has created hostility between nations. Working together as Earthlings instead of as individual countries will unite them by providing a common goal. These shared motivators will unite all humans on Earth. A joint effort will also keep Mars from being colonized by one Earth country. Private companies like Space-- X or Mars One may be able to send regular people to Mars even sooner than national space agencies (MacDonald et al.). Mars One volunteers would make a one way trip to the planet because they don't have the technology to return the humans to Earth (MacDonald et al.) Mars is a dream for many people, and the travelers could be anyone.
