The solution for Earth isn't going to be some pie-in-the-sky terraforming (which, I'd like to note, means "to make Earth-like") project, but changing our psychotic economic system that depends on infinite growth and consistently elevates the worst of us into positions of power.

That's why I think we'll never manage to unfuck ourselves. There's just way too much power invested in keeping things the way they are

We won’t have the ability to terraform Mars until we try to terraform Mars.

Perhaps Mars’s greatest contribution to our civilization wont be that it hosts cities or future life, but rather simply that it gave us a place to experiment so we could test things once before implementing them here.

So why not just fix it here where it's millions of times easier than doing it on Mars

¿Por qué no los dos?

Also, I'm not entirely convinced that the problems are analogous. Mars needs to be warmed up, Earth needs to be cooled down. I think a more appropriate challenge would be terragorming Venus.

Why not both?

Although Mars is still a terrible candidate for terraforming. It's at the outer edge of the goldilocks zone, and even if you can solve the temperature, radiation, and atmosphere issues to create a viable ecosystem, it's still going to cause problems for humans thanks to the low gravity.

Venus on the other hand could realistically function as a second earth if we clean up the atmosphere.

Okay but what if we lived in the moon

The tech needed to terraform mars is thousands of years away. There isn't enough water or O2 on Mars to terraform it. As well as a whole host of other issues that we currently have no idea how to fix. (The lack of a magnetosphere is a huge one)

I definitely don't agree with that take.

First of all, "terraforming" means "to make Earth-like"; climate mitigation is one thing, but if we let things here get bad enough that we have to start thinking about terraforming Terra, we've pretty thoroughly screwed the pooch at that point. Ending up with an Earth that is no longer Earth-like would mean that things have gone sideways so badly that I doubt we'd have the industrial capacity or resources to deal with it.

Second, terraforming Mars involves a vastly different process than unfucking our climate and ecosystems. For example, Mars has a very thin atmosphere, which on top of being thin is mostly CO^2^ and doesn't have more than trace amounts of oxygen. There's also no magnetosphere to speak of because its "core dynamo" essentially died when its core cooled down and plate tectonics etc stopped being a thing, meaning that any atmosphere you do manage to generate is continuously getting blasted away by radiation.

Terraforming Mars essentially means pumping more energy and gases into its climate system via whetever method, while the problem here on Earth is that we've pumped too much energy into the climate system and we'd have to somehow get it "out" again.
