Mars would be awful to live on. Cosmic radiation means you have to be underground most of the time. The dust is microscopic and electrically charged, so it gets fucking everywhere. Oh, and it’s full of toxic chemicals so not only does it chafe it’s poisoning you the entire time. There’s no water, no food, and barely enough air to call it an atmosphere. You’ll be locked in a tiny tube eating yeast protein for the rest of your life, which won’t be long because you’ve got perchlorate poisoning.

I guess what I’m trying to say is: I wish Elon the greatest success in his emigration to Mars.
