We’ll probably fuck up our own planet badly enough that we’ll never actually get the chance to try terraforming Mars

I heard sometime interesting regarding that recently, if we have the ability to terraform Mars, we’ll have the ability to hear on earth. 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.
