Mining isn’t a huge source of greenhouse emissions. It’s not good for the local environment, but it’s necessary. Recycling and reuse is also a grand idea, you’re right about that. Except for plastics, which never made sense.
Electric cars are unequivocally a good thing. Every electric car takes a fossil fuel guzzling car off the road. Once a family has an electric car they tend to use it whenever possible, making the effect even more pronounced. Some people float the ridiculous argument that they emit more greenhouse gases in manufacturing and mining than they save over their lifetime. Firstly, gasoline cars also cost energy to manufacture and gasoline also takes energy to extract and refine and transport. Secondly, electric cars break even within the first few years of use. Even in todays world where the electric grid still has a lot of fossil fuel generation.
