Most mining can be harmful in some way or other. That is not to say we shouldn't pay close attention and look for better ways to do things. We have "Blood Diamonds" and it is said that "gold mining is one of the most destructive industries in the world." Yet women everywhere still wear diamond rings.And introduced some new pollutants. Eg. from extracting lithium
In this case I found an interesting post from:

There is a question of volume. I’ve got an electric van with 20kWh worth of battery. For the sake of argument, there might be 1kg of lithium maybe 1kg of cobalt. I’ve been driving it 4 years now and I’m still using the same 1kg of lithium that I did when I bought the van.
Now consider if I had been driving a ICE vehicle for this length of time. I average about 10,000 miles a year and my last car was doing 40 miles per gallon. I was using 250 gallons of oil per year, or 1,000 gallons over the 4 years I’ve owned the car. Something in the region of a tonne of oil every year.
I’m under no illusion about the problems of lithium and cobalt mining. The oil industry has its own very significant pollution problems.

As he points out, the lithium mining damage is a 1 time event, but the extraction of fossil fuel has its own issues and combustion release of carbon-dioxide and pollutants is ongoing. And in his example, he gets 40MPG!
