The issue is once you educate yourself in science and engineering, you realize that teraforming planets isn't something you just do. And you can't realistically rely on a technology that doesn't exist. The real problem here is one of education. The facts and the seriousness of climate change do not support his dumbass argument, and we'll all be dead by the time everyone comes to an agreement and realizes, oh shit nobody is going to save us from climate change but us.

We can't keep astronauts aboard the ISS indefinitely, even with constant restocks from Earth, and we're supposed to go even further out of our orbit to the moon or Mars and they're going to be fully independent? Why not save the cost and try to make a human terrarium here on Earth?

edit: not arguing your point, just extending it a bit.

Yeah, I won't knock people trying to leave the earth. I work in space stuff, and I would love nothing more than to see us realize multiplanetary habitation. but I definitely think we need to be good stewards of our planet. We don't exactly have a plan b. And realistically, we may never have a plan b. Science is hard.

I'm not saying don't try to leave the planet, but also let's look at feasibility here on Earth.

I was agreeing with you, in case that wasn't clear. Lol

Glad we're all on the same page. It's terrifying looking at some of those other platforms and seeing what kind of thoughts are out there.

I gotta imagine making the Sahara Desert habitable is a lot easier than making Mars habitable. The Sahara at least has breathable atmosphere, a 24 hour day, solar intensity that our plants are well adapted to using, and is relatively close to resupply from population centers on Earth.

And Sahara was a jungle pretty recently.

And even so, that might be the easiest part of the whole terraforming thing. It only gets worse from there.

The closest thing to a self sustaining thing is that Neom city they're trying to build. It's basically an arcology. And it's already failing.
