What does it mean to Terraform mars how does the process take place?

Terraforming Mars refers to the hypothetical process of altering the planet's environment to make it more Earth-like and suitable for human habitation. This could involve several strategies, such as increasing the temperature to melt polar ice caps, releasing greenhouse gases to thicken the atmosphere, and introducing microorganisms to produce oxygen. The process would require advanced technology and significant time, potentially taking centuries or longer to achieve a stable, habitable ecosystem. Ultimately, the goal is to create conditions that support human life and agriculture on Mars.
