Mining/refining is a significant source of pollution on earth. It’s interesting that in talking about economic impacts, we don’t talk about the reduction in “expense” to our environment and health. If the current mining industries could be replaced with those that do not pollute our living space, there are significant gains to be head in the form of more usable land and better ecological environments. Additionally, a number of much cleaner technologies are currently very expensive because of the scarcity of resources and pollution involving mining. Lithium for batteries is one example. Disposition of used batteries would remain a problem, but perhaps similar off-world approach could be used there.
