Virtually any manufacturing leaves a "non environmentally friendly footprint". Including batteries, which I agree with. But I would add - today's batteries. But here progress and the situation does not stand still, and today there is active work on the search for new materials with new properties for the development of new generation batteries with better characteristics, including those that do not use the above-mentioned chemical elements. The second nuance - it is difficult to compare the harm and threat from global warming caused by the huge amount of emissions from internal combustion engines with the harm from the extraction and use of these metals. It is necessary to understand one thing - we live at the beginning of the era of electric energy in the automotive industry. I am sure that in 5-10 years, if we come back to this topic here, we will be very interested in discussing the changes in this short period of time 
.
There is some truth to that because we live amidst a tendency among people who want to live more practically and easily, so they don't really care about costs. The automotive industry continues to make strides in creating a new generation of environmentally friendly cars and we are even at a state of technological sophistication where people no longer need to drive because cars use sensor commands to run them. Even though the market is not big and not yet common, I am sure we will see the development of the automotive industry continue to develop with new ideas offered by its products..In the next five or ten years we will see how the process of technological development in the automotive sector will continue to develop. When we return to this post there will probably be many other debates that we will discuss with each other. Losses and threats will continue to exist in any sector, including the process of developing electric cars, because there are levels of weaknesses and strengths that place them in certain problems.
