There is no need to colonize Mars because we still need to overcome Earth's problems. Mars is the fourth planet, a habitable planet with no atmosphere, and its average distance from Earth is 225 million kilometers from Earth. The fact remains that Mars is habitable; colonizing it will be a problem. A trip to Mars will take us time, money and give us 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 really terrible place." Earth will be left aside if we colonize Mars because we will pay more attention to exploring Mars. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

In the article Pros and Cons of a Human Mission to Mars by Demarcus Briers states that “The cost of the human mission to Mars would be over $20 billion… which could be improved” Yes, colonizing and exploring Mars will waste our money . The United States can now pay 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 in Mars could help us solve climate change. Climate change can destroy the human race; we want to place Earth, so we don't have to start from scratch on Mars. Specifically on investments on Mars, NASA wastes about 360 million a year, and the United States spent 2.5 billion dollars to build the Curiosity rover which is on Mars. On the other hand, solving climate change through 2050 will cost $359 trillion. Regardless of Mars being Plan B and starting from scratch, we can solve Earth's problems. Furthermore, investments are 360 ​​million per year, more than 20 billion dollars to explore Mars, but money to live there, build domes, resources: water, oxygen and transport excluded. This list of wasted money on Mars is still ongoing, but if people reflect on the fact that Earth is more important than Mars, humanity will be able to live for generations. The mission to Mars will represent a risk for humanity due to the new experience we will face. In addition to the fact that Mars is far from Earth, the time to get there can affect us. The trip to Mars will take 39 days if we go with our fastest spacecraft, on average it is about 150-300 days. People are not used to being on a plane and the only maximum duration on a plane is 18 hours. He imagines that by staying in space for 39 days people would experience many side effects such as long-term weightlessness, muscle atrophy and skeletal deterioration. In addition to side effects, people can die from asteroids, new diseases on Mars, lack of oxygen and weather conditions. Mars is different from Earth; Mars gets hit by 200 rocks a year, is subject to severe dust storms, and has radiation all over 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: “As technology develops, there will be a prolonged period in which astronauts on Mars will not be able to contact Earth because they will be on the far side of the sun.” Therefore, people who go to Mars may take the risk that Earth does not?
