If we could terraform Mars, it would be easier to teraform Earth. All our stuff is here. There's an atmosphere and water. Temperatures don't fluctuate between -30°F and 125°F based on what time it is. We don't have giant ass dust storms that black out the sun. You don't get skin cancer from standing outside for half an hour. Most importantly, there isn't a five year travel distance between travel routes across a void.

It's easier to imagine the death of the world than the end of capitalism.
