In a paper just published on January 4th, Alberto Fairén of Cornell University and the Center of Astrobiology in Madrid discusses the impact that human exploration of Mars is likely to have on that planet. The Anthropocene is a term used to describe the massive changes that have taken place to the Earth resulting from human interaction and activities, and for a similar effect to take place on Mars in a few decades would make it the first multiplanetary geological period.
The changes to be expected on Mars range from unavoidable microbial contamination of the environment to wholesale geographical changes necessitated by habitats and eventual pizza joints (per Musk) that will spring up over time.
One hopes that lessons we can take from the treatment of our own planet, which in many ways hastens the need to find a spare one, could help inform how we should treat our potential new home. How that plays out, and with what wisdom, we will know in the fullness of time, or at least our Grandchildren will.
