There's No Free Lunch With Electric Vehicles?

Electric vehicles are largely sold in developed countries on the basis of reducing 'greenhouse gas' emissions. Such vehicles also do not add to the potentially health-damaging properties of poor air quality in towns and cities. Electric vehicles naturally depend on battery technology, requiring Nickel. Health problems for locals are now appearing linked to Nickel mining in Indonesia (https://www.theguardian.com/global-development/2022/feb/19/we-are-afraid-erin-brockovich-pollutant-linked-to-global-electric-car-boom ). The largest Nickel reserves are in Indonesia. This makes the mines for this metal, highly attractive to the manufacturers of electric vehicles/ batteries. There are, however, downsides for Indonesians living near the Nickel mines. Near the mines, ground water is heavily contaminated with the mutagen (cancer-causing chemical) hexavalent Chromium. There also appears to be a high incidence of lung infections, in people in living in close proximity to the Indonesian Nickel mines. Rather obviously, improving the health of people in one part of the world, should not be done by damaging folk in other locations. No industrial process is, however, completely benign. Perhaps it's not a great idea to simply attempt to replace all diesel and petrol-fuelled vehicles with electric alternatives? We may need to rethink transport policies and plan for fewer private vehicles?
