Humans on the Loess

The earth is gone, the atmosphere is as thin as a bubble, yellow sand is flying in the air, and the sea climbs onto the land. Humanity ran away, spent all its resources, abandoned useless people, and headed for Gliese 581d, which is about twenty point three light years away. The last mercy mankind has for useless people is loess. A space station with a complete ecosystem is located near Mars and flies with Mars as the center.
