Yeah you may not want that - Musk’s plan to get to mars involves, not necessarily _intentionally_ but with no attempt to avoid, ruining the earth for everyone else. He and his billionaire friends that want to colonize space have said they intend to do it by any means necessary, including by walking on the backs of us poors, if it means their progeny can outlast the rest of earth.

Mars' gravity is 0.39 of Earth's. I don't understand how anyone thinks that can support a permanant colony of humans.

The gravity difference is probably the least problematic issue with living on Mars.

And killer dust almost as bad as on the moon. And lots of radiation.
