Waaah trying to fix the environment is too hard.
It’s easier to simply create a new home on a world without air, water, food or energy millions of miles away.
I know if human civilisation survives more than a million years here on earth then yeah eventually we’ll have to leave, but leaving now??? So shitty.
Why Mars? There’s another planet in our solar system that’s even closer and has a breathable atmosphere, a protective magnetosphere and temperatures mostly tolerable by humans. We could try to fix that place that place up first, seems like it’d be a less of a hassle
Since clearly the Earth is done for, how do you propose thinning the atmosphere of Venus?
