The social, ethical, and environmental issues surrounding resource extraction are important but not unique to EVs. They are being discussed in the industry, and alternatives are already entering the market. They are far more likely to be addressed by the sustainable technology industry as the industry matures than, say, the litany of horrors of oil extraction. The key here is to keep the focus on carbon, specifically carbon inputs as they impact climate change. Don't let the better be the enemy of the good. The alternative is much, much worse.
