p.s. Mining operations on Earth are dirty not because it's an insolvable problem, but because they are allowed to be. They emit as much pollution as they can get away with - why wouldn't they? They would find ways to make the process cleaner if there were any financial incentives to do so, or if they were required by regulations (which were actually enforced).
