That's a big assumption. It is impossible to tell if any automobile that uses antifreeze causes more harm to the environment than an EV battery. Antifreezes are used at home to prevent boilers and heat pipes from freezing and bursting. This liquid is called, "glycol." Another type of antifreeze is used for cooling automobiles engines, but EV's have battery temperature management systems that use coolants, too. It does not mean that these coolants are being sprayed all over the road. EV's also have drive units and pumps with gears immersed in oil, brake fluid, and windshield washer fluid. Lithium is not as abundant as you have been made to believe. Small traces of it are present in salt water, and it takes a lot of time for the water to evaporate. Once the water evaporates, it leaves behind "salt." The next step is to separate microscopic pieces of Lithium and other minerals. Keep in mind the Lithium in pure form (lithium dust) reacts violently to water and other liquids
Mining can be done in more efficient ways, of course. The same can be said for oil, natural gas, methane extraction, or gold mining too. But through the years, haven't we left scarred earth behind? I am not taking one side or another. The truth is that in order to live as comfortable as we do today, earth takes a toll. An EV is not going to save the planet any more than an ICE automobile. The main difference is that an EV does not emit gasses out of a tailpipe.
