Cheer up, until humans arrive there, Mars is a planet populated by robots, and they don't make big messes. Even the first colonies will have to be resource-efficient if they want to prosper, hopefully diverging from our current wasteful mentality.
I've thought a lot about that, but on the moon. When/if we get to mars, and someone drives their rover from one place to another. The wheel tracks in the dirt can, eventually, be erased by the winds of Mars.
On the moon, there is no such refresher. In the year 12022, there will be up to 10,000 years of rover tracks covering the surface of the moon. I just wonder what will become of the Apollo 11 landing site. I can imagine it in a bubble in the middle of some mall on the surface of the moon.
