Since the beginning of modern space travel, people have thought about colonizing other planets to avoid the global warming-related problems we will face in the future. As technology improved, this idea has become more and more relevant in our day. Global temperatures have never been so high and, scientists guess that global warming-related problems have the potential to cause the extinction of Earth. Knowing this, many people have said that humans should try to colonize another planet to continue its existence. These problems have to lead to some arguments around the world about some key questions. Some people believe people should try to colonize another planet, while some argue that preventing global warming should be the primary aim.
The average temperature of the world and the amount of water in it are the main reason it is hospitable for human life. The world is the ideal planet for humans to live in because it has all the necessities for human life while having liveable temperatures. To this day, Kepler-452b is a planet known as earth 2.0 because of its similar characteristics. It is over five times larger than Earth and, it is a little warmer with an average temperature of −8 °C. However, the planet is 1,402 light-years away from Earth. If we consider this, we can see that it is impossible to colonize or come close to Kepler-452b with modern technology. The most talked-about planet right now is Mars and, many people believe Mars is the planet to colonize. Despite being extremely close to Earth compared to other planets, Mars doesn’t have enough water to feed people, along with the fact that it is cold compared to Earth.
Since the Industrial Revolution, global temperatures have risen by approximately 1.2°C, and if temperatures continue to expand at this rate, they will be 1.5 °C above the pre-industrial levels between 2030-2052. If temperatures rise, many cities along the coast will be flooded because of rising sea levels. Although it might affect coastlines in a way which they might be at a level with the sea, which would make the cities unhabitable. If temperatures rise to their expected point by the end of the century, we might see a weird landscape of Earth.
In the end, I would like to say that colonizing another planet with the modern technology that we possess is close to impossible. However, in the future, colonizing an outer planet might be possible if technology improves and new planets like Earth get discovered. Our major priority should be to save the Earth because it isn’t probable to find a planet with better conditions than Earth close to us.
