With planet Earth slowly disappearing, humans have come to the consensus that in order to maintain developing the human race, citizens of Earth will have to sustain lives on different planets. This idea has brought many scientists to investigate the different planets and their factors. Mars is included as one of these planets. However, on Mars, there are major factors that deny the possibility to maintain lives there. Lack of oxygen, food, sanitized water sources and sustainable soil conditions are the biggest issues of living on the planet Mars. Of course, there are solutions to these problems as well.
Humans will be able to sustain lives on Mars, as long as they have food and enough oxygen. These two issues will be eliminated if we, humans grow plants on Mars. “How are we going to grow plants with no oxygen and unsustainable soil conditions?” you say. Simple. I have come up with two solutions that will eliminate these worrying issues. To start off, both solutions will require a dome with a valid source of oxygen to create a friendly atmosphere for the plants to grow in. This is due to fact that the Martian atmosphere mainly consists of Carbon Dioxide (95%). Plants must undergo a process known as Photosynthesis, where plants consume the reactants light and chlorophyll, producing oxygen and glucose, allowing for animals to grow and a friendly environment for both plants and humans.
My first solution that I am promoting is the idea that humans bring valid soil sources to grow the plants that will help us to live. Since Martian soil is not eligible to grow any plants, if we, humans bring soil sources that are capable of growing plants, we will be able to live on Mars. These soil sources may consist of most materials, such as human waste and the soil from Earth (which contains organic matter and minerals). Along with the dome, humans will be able to grow plants with this option. However, as this may sound like a good idea, there is sadly a limited value of such materials. The earth has a limited amount of soil that will run out one day, and humans will not be able to produce enough waste to grow the plants. This makes it an environmental issue.
Again, bringing food from Earth to Mars is another possible solution. This way, humans will be able to live in an environment with less plants, as they only need plants for breathing purposes. However, this solution will not be the *ideal solution, as it will costs tons of money transporting a huge quantity of food to provide for over 7 billion citizens. Furthermore, like the previous idea, there are only limited amounts of food sources available on this market. Despite the fact that food can be genetically modified to produce larger quantities, I believe that GM (Genetic Modification) is ethically not the right choice.
Thus, I think that it is possible to live on the planet Mars by growing plants using sustainable soil sources rather than transporting plants. Humans will be able to survive and develop for longer periods of time using this method.
