Terraforming Dreams

Some visionaries propose terraforming Mars — deliberately warming the planet to thicken its atmosphere. Releasing CO2 from polar ice and soil could, in theory, trigger a greenhouse effect, but studies suggest Mars lacks enough accessible CO2 to build meaningful pressure.

More realistic near-term plans involve paraterraforming — enclosed habitats inside domes or underground. The soil supplies building elements, the atmosphere provides CO2 for plants, and polar ice offers water. A settlement would not need to transform the whole planet, just create small pockets of habitability.
