Your question is premature because you're comparing the Earth of today to the Mars of today.
The short-term goal (short in the grand scheme of things, that is) is to build a colony on Mars that can satisfy the first level of Maslow's hierarchy: air, food, water, shelter. After that, moving to Mars will be a much more attractive prospect to a non-negligible number of people.
- leto_ii 7y ago> The short-term goal (short in the grand scheme of things, that is) What is the timescale you have in mind? Hundreds, thousands of years? If this is the case, it makes more sense focusing on keeping Earth livable. I think Kim Stanley Robinson had a nice take on this in "Aurora" (https://en.wikipedia.org/wiki/Aurora_(novel) https://en.wikipedia.org/wiki/Aurora_(novel)). Without giving too much away, one of the core ideas of the novel is that there really is no place like home. > After that, moving to Mars will be a much more attractive prospect to a non-negligible number of people. Hmm, what makes you think that? Again, how bad should Earth get before living in a place where you can't go outside is a better option?
- njarboe 7y agoIt is just a novel. His ideas on ecosystems are as much science fiction as traveling to other solar systems. Not scientific truth. We really will have to try living on other planets before we know how it works.
