Hope you didn’t think we could colonize the Moon once we permanently screw up Earth. It's toxic to humans.
Hope you didn’t just think we could move up and colonize the moon once we permanently screw up Earth. New research suggests that Ernie was right all along: The moon might be a nice place to visit, but living there might actually kill you. There’s a good chance that moon dust is toxic to humans. The worst thing about lunar dust is that it’s very fine-grained and the grains are sharp. The tiny particulate size means it gets everywhere — living quarters on the moon would inevitably have a fine coating of dust, which would hitchhike in on protective gear and be difficult to get rid of. And once it ends up in your lungs (which it would), it could inflame airways and potentially increase cancer risk. The sharp edges also mean that the dust can irritate your skin and eyes. Particles on the moon don’t get buffeted around and eroded by wind or water, so they’re not smooth like grai...
