What would happen if large-scale lunar mining operations
I was talking to a few people about the recent news about mining the moon and someone mentioned that this is a bad idea because it'll decrease the mass of the moon (and increase the mass of the Earth, as the raw ore comes home for processing), thus affecting the tides and potentially destroying some or all ocean habitats. On a purely theoretical level, I realize that this is true.
