Overpopulation, a lack of natural resources, and pollution are all major problems facing humanity right now, and if unsolved, could prove disastrous for our entire species. The goal of our project was to discover which factors would have to be changed on Mars for the possibility of life on it, so that we would be able to colonize and live on its surface. We believe that a terraformed Mars would solve a plethora of different problems, and if possible, would be a very good idea. While the cost of a project of this magnitude would definitely be big, we were able to create a plan that, theoretically, would cut costs drastically compared to the original Mars exploration plan of NASA in the early 21st century. For our experiment, we tested three different variables and their impact on plant growth (soil composition, temperature, and atmospheric pressure). Our initial hypothesis was that soil composition would be a negligible factor, while temperature and atmospheric pressure would create a large difference. This hypothesis was proven to be correct, as the plants failed to grow at all at a temperature of 5 degrees Celsius.

From our results, we were able to conclude that to be able to colonize Mars, multiple things would have to be changed. We would have to ensure that during the terraformation process, the temperature would be raised to a suitable range and that the atmospheric pressure would be increased to be far more than it's current value (less than 1kPa). However, we wouldn't need to bring excessive amounts of soil from Earth, as we saw from our experiment that it had minimal effect.
