Im a Canadian geologist so I obviously dont have any personal stake in this but I do want to share my thoughts.

I think anti-mining sentiment is understandable in most places but not always justifiable. Lithium mining is absolutely required to transition from fossil fuels. Unless the number of cars on the road is greatly reduced, replacing them with BEVs will require significant amounts of lithium or improvements to Na ion batteries. There is not enough lithium available to get by just on recycling.

The question then becomes: where should this lithium come from? If it is not mined in western countries like USA or Canada, it will be mined by China or developing countries. In this comparison, who has better environmental regulations? Which countries have more human rights abuse?

If we decide that we can mine these deposits in the west, there is still a question about where they are mined. Do we extract lithium from basinal brines? My understanding is that these are generally more environmentally risky than extraction from pegmatites (the deposit type in New England).

The final question becomes, which communities will have to accept this mining? In Canada, most of the time it is indigenous communities that suffer most of the negative impacts of mining. There are many benefits to the communities too (usually), but the indigenous communities do not have nearly as much political sway as say rich cottage owners might, so their preferences and desires often get steamrolled by government in the name of "progress".

The unfortunate reality is that if we want to get rid of fossil fuels, we need to do a lot more mining and extraction or come up with some serious technological and societal innovation. In a globalized economy, saying that you dont want mining near your home means that you want some other people to deal with the potentially negative consequences of it. I am not saying that we need to allow all mining everywhere, but these are important ethical considerations that we have to make when talking about how we want society to progress.

Sorry for the rant.
