Personally, as a rabid environmentalist, I'd be happy with more mines IF said mines were less destructive to the local environment and weren't so completely horrific, health-wise, to the local residents. I'm thinking of the proposed Pebble mine in Alaska that, if it went ahead, would have toxic tailing piles and other sludge that could conceivably leak and permanently destroy a multi-million dollar salmon fishing industry. Or other mines that rely on open-pit techniques that destroy the land permanently - even if they 'put the earth back' once they're done (which often they don't), they usually have ruined the land for any farming, ranching, or other use (and again, they are irretrievably destroying local ecosystems, which thanks to habitat loss, are often the last refuges for multiple species). Or pollute local aquifers and rivers to the detriment of anyone living downstream (see: Amazon gold mining, coal mining in Appalachia, etc., etc )
IF mining companies were actually willing to explore less-destructive methods of extraction and be held fully responsible for any potential damage they might cause (to the tune of non-dischargable insurance bonds in the millions or billions of dollars it would take to clean up after them, if they have any hazardous waste discharges/illegal disposal), I'd be a lot more onboard with new mines. But of course, the companies don't want to do that. They want to pull the good stuff out of the ground, and then take the profits and run and leave the local communities holding the bag for the destruction they cause. This has been going on for several hundred years at this point, so I don't hold out a lot of hope for change.
As a rational environmentalist, I look around at all the crap I and other people use which is mined, and think "holy crap the US should be pockmarked with mines to afford this level of consumption." Like I said, I'd prefer to see no net imports of minerals to the US. All things sold should be recyclable and an organized recycling network should be set up such that 99% of materials are recycled. If we want to transition to renewable energy, we need to mine. Beyond that, our social goals conflict with our environmental goals. If we want to keep bringing up the standard of life of the poor in the US and around the world, we need more mining. I don't know where that line is drawn, but I'd like to see all the costs and benefits go to the places the materials are used, especially if they are carefully regulated and transparent. "Made in USA 2030" would be a great and effective slogan, and also it would be nice to see more messaging about reducing waste.
That said, carefully regulated means efficient and fast regulation. If a mine cannot be allowed at a location or can be allowed only conditionally, then that is OK, but it should be determined quickly, and not drawn out over years decades.
A thing about oil and gas is that it is very minimally invasive and has few side effects. An oil well is like a very small straw in a very large cup, and with new technology the size of the cup is growing very large. From there it is preferably pumped (not trucked or shipped) through a small pipe to its destination. Really, carbon dioxide and whatnot is the only significant drawback to these.
For a mine, it is the reverse. It will always leave a large hole in the ground, and almost always a larger pile of waste rock next door. If there are lingering effects, they will usually be very local. It actually does not make sense to refill the mine, because the energy expenditure is almost as large as it was to mine in the first place, hence nearly doubling the emissions or quantity of battery.
Modern mining regulations, especially since the 1990's, are far more stringent about environmental protection than those which came before, though I am not sure how effective they are over the long run in all cases, for example some pit lakes will be highly acidic for centuries. But as a comparison, I once (for the year I did that type of thing) sampled water from a mine cerca 1900 which had built its tailings and waste dumps directly over a stream. The pH was 2, and every gallon of water we sampled from it weighed a full pound more than a regular gallon of water because of all the dissolved minerals. The stream carried this stuff through all sorts of habitat, and eventually past drinking water intakes (and also was a super fund site). However, now there are requirements to build those far from water, and to line the bottom with plastic and clay as described above, and to put a cap on it to direct precipitation away. So there will still be a very large negative effect, but it should be strictly local.
Anyhow, as an exercise I think people should look around and look at how much of the stuff around them which is visible
right now is entirely a result of mining, how much was made out of renewable materials but shaped by mined materials, how much was merely transported by mined materials, and how much is in a form and location such that mining played no role. It is shocking how much stuff tends toward the beginning of that order.
