EVs can't cross oceans yet.
I haven't studied it in detail, but there are enough people who have that have drawn the opposite conclusion, I kinda have to say I don't think we know and that I will just keep living in a way that is a bit more sustainable each year, mostly because I want to live in a manner that increases abundance on any land I own and will sustain future generations.
I guess I'm in kind of an oddball corner since I don't worry much about climate change and do worry about synthetic hormones in water or chem trails covering everything in heavy metals.
