The irony about all this is that the CO2 is by far the least toxic component involved with the mining of the metals needed for electric vehicles. I would actually entertain the notion that CO2 is not toxic at all, especially since it's literally what plants breathe and convert to oxygen. If CO2 was so incredibly toxic, why do we allow farmers such as pot growers to use CO2 generators in their grow houses? I mean, if it's so toxic, why would they do such a horrific thing?,(reply>), I see someone has no fucking clue about greenhouse effect and what an atmosphere is.<br><br>CO2 isn't "toxic" for the planet. But unless you want to live in a pressure cooker (which humans aren't very good at), I wouldn't recommend having too much of it.
