Earth has a population of more than six billion people. As this number continues to grow, the populated land masses fill up, and it seems that eventually they will all be overcrowded. Many areas are already showing this overpopulation, such as large American cities. Some countries do not suffer from overcrowding due to high population, but to a high ratio of population to resources. As the natural resources of an area are depleted, the quality of life of the people who live there decreases. If the human race is to prosper as a whole, there must be enough resources to support the global population.

If getting to Mars is the biggest hope for saving human civilization, then our next step is to create the technology to do it.

In order to support our increasing population, we must learn to harness new resources.

In order to transform Mars into a planet we could successfully inhabit, we would need to modify the atmosphere to get rid of the carbon dioxide and replace it with nitrogen and oxygen. The first step in this process would be to melt the southern polar ice cap, releasing massive amounts of carbon dioxide into the air. By doing this, the greenhouse effect could heat up the planet.

Liquid water is necessary for life and metabolism, so if water is present on Mars, the chances of life evolving is improved. The Viking orbiters found evidence of possible river valleys in many areas, erosion and, in the southern hemisphere, branched streams.

The atmosphere on Mars is thick enough to prevent deadly storms from reaching the surface, and is mostly made up of carbon dioxide, with about 5% made up of oxygen, nitrogen, water, and other noble gases. Because of this carbon dioxide, it is currently poisonous to humans. However, with the introduction of plant life we could turn the carbon dioxide into breathable oxygen.

The planet’s oxidized soil means we could grow food, and the existence of methane gas means we could create fuel.

Temperatures on Mars vary from -133 C to 27 C, compared to Earth’s -88 to 58 C. This, of course, means that humans would have to have some means of staying safe at lower temperatures, if we chose to inhabit an area where the temperatures got that low.

For thousands of years, humans have looked up and pondered their place in the cosmos, the intriguing question of whether there’s life on the Mars has obsessed mankind for generations. So far, scientists have not found life on Mars, either living or extinct. Several space probes have gone to Mars to study it.

At least two thirds of Mars’s surface is more than 3.5 billion years old, the possibility of life on Mars is a subject of significant interest to astrobiology due to the planet’s proximity and similarities to Earth.

The hopes for a future on Mars have grown in tandem with the technological advances that have expanded our knowledge about the fourth planet from the Sun.
