Terraforming Mars is the process of modifying the Martian environment to make it more Earth-like and suitable for human habitation. This involves altering the atmosphere, temperature, and surface conditions to support life. Scientists propose various methods, such as releasing greenhouse gases to warm the planet and creating bodies of water. The concept of terraforming Mars has been popularized in science fiction and is a subject of serious scientific research. It raises questions about the ethical implications of altering another planet and the potential for future human colonization. Successful terraforming could pave the way for sustainable living on Mars.
