What is easier? Not mess up this planet, or Terraform Mars?

Belter, our future is in orbital habs. Going downwell is for tourism and archaeology.

It’s not worth doing because it is easier, but because all of our eggs are in one basket (planet). We know of disasters that can wipe out almost all life on a single planet. Of course, there are also disasters that can wipe out all life in one star system (and one region of the Galaxy). So, ideally we need to colonize many worlds in many different parts of the Galaxy, but baby steps. Step one is to have a sustainable population on multiple moons/planets/stations of this star system before we jump to other star systems.

I don't know. Have you seen humanity? I think teraforming another planet is probably easier than not fucking up this one

Vastly easier to not only stop but also undo all the damage here than to do anything of consequence on Mars.

The best way I heard this put: Before we worry about terraforming Mars, maybe first we should stop Venusforming Terra.
