If economic exploitation of Antarctica, which is only a few hours away from "civilization", has water literally everywhere, and where the air is perfectly breathable is currently not viable, I can't imagine what it would take to make Mars, or mining asteroids, viable.

It's also kind of vital for the balance of the planet's ecosystems, as we're slowly finding out. If we melt it to get materials under there, there's a sizable chance of long term regret.

Whereas Mars doesn't have an ecosystem at present and no species to endanger.

I want to make other planets livable so we can stop killing this one so much.

What (insufficient thought it might be) political support there is for efforts to stop killing this planet is based largely on the idea that "its the only one we have", so I'm not sure that really works.

I would certainly be in favor of terraforming Mars, and then seeing what could be done.

One might (or might not...) want to wait until we have clear evidence that it is indeed sterile. In either case the first thing to do would be to seed it with engineered robust lichens, or the like, just to get things started.

Afaik, it's viable but there is a global ban on Antarctica exploitation till 2048.

A quick search lead me to this:

>it was quite clear before it became law that there was no real commercial interest in mining or oil exploration in Antarctica for the foreseeable future. [1]

Of course, a vein of pure gold would be worth mining, but I think the main reason is the massive overlay of ice makes most of the minerals inaccessible, except at the fringes of the continent.
