It Might Be Less Expensive Than Fixing Earth

Terraforming seems like a huge undertaking. And that entails a hefty price. According to some estimates, the project would take around a century and cost $2 to $3 trillion. A plan to terraform Mars would be the equivalent of the tenth-largest country on Earth in terms of GDP if it were implemented and $3 trillion were devoted to it. Few people have $3 trillion available to them.

Despite the high cost, it might also be a wiser financial decision than attempting to solve the issues on Earth. Between 2015 and 2035, it is projected that the world will invest around $40 trillion in the fight against climate change. Now, that $3 trillion seems like a really good choice.

If we are successful in stopping climate change, it may take Earth a full century to recover. Initial terraforming could take 100 years, and getting Mars to a habitable state could take another 300–600 years.
