There is no need to colonize Mars because we still need to make terrestrial problems superior. Mars is the fourth planet, a habitable planet without an atmosphere, and its average distance from Earth is 225 million kilometers from Earth. The fact remains that Mars being habitable, its colonization will pose a problem. A trip to Mars will take us time, money and cause problems. We don't want more problems, we need to solve Earth's problems first. Some people agree with me, for example, in a Ted Talk, Luciana Wickiewicz, an astronomer, said that going to Mars is terrible: “Compared to Earth, Mars is a pretty terrible place. » Earth will be left behind if we colonize Mars because we will pay more attention to the exploration of Mars.

In the article Pros and Cons of a Manned Mission to Mars by Demarcus Briers states that "The cost of a human mission to Mars would be more than $20 billion...which could be improved." Yes, colonizing and exploring Mars will waste our money. . The United States can now pay for the national debt, education, climate change, global warming and disease. We have money as a resource for something we need; we must repair the Earth. For example, investments on Mars could help us fight climate change. Climate change can destroy the human race; we want to settle the Earth so as not to start from scratch on Mars. When it comes to investing in Mars, NASA wastes about $360 million a year, and the United States spent $2.5 billion to make the Curiosity rover on Mars. In contrast, addressing climate change through 2050 will cost $359 trillion. Even if Mars is just a plan B and we start from scratch, we can solve Earth's problems. In addition, investments amount to 360 million per year, or more than 20 billion dollars for the exploration of Mars, but the money to live there, make domes, resources: water, oxygen and transport not included . This list of wasted money on Mars is ongoing, but if people think about the fact that Earth is more important than Mars, humanity can live for generations. The mission to Mars will be a risk for humanity because of the new experience we will have. In addition to the fact that Mars is far from Earth, the time to get there can affect us. The journey to Mars will take us 39 days if we board our fastest spacecraft, on average about 150 to 300 days. People are hardly used to being on a plane, and the only maximum time they spend on a plane is 18 hours. Imagine that by staying in space for 39 days, people would experience many side effects such as long-term weightlessness, muscle atrophy, and skeletal deterioration. Besides side effects, people can die from asteroids, new diseases on Mars, lack of oxygen and weather conditions. Mars is different from Earth; Mars is hit by 200 rocks per year, experiences violent sandstorms and radiation across the planet. In the article Pros and Cons of a Manned Mission to Mars by Demarcus Briers, he explains that there is a lack of communication in space. The article states: "Once the?
