It would be nice to live in a city and not be bothered with the smell, noise and health risks of thousands of engines. It would also be nice if our environment wouldn't be plastered with microplastics.
Right now, natural gas is dirt-cheap, plentiful, and relatively clean, and can provide the cheap electricity needed for EVs.
Also, the most ideal solution in my book would be to do less work, not more. Geoengineering requires quite a lot of work on a permanent basis.
Does burning fossil fuels distribute microplastics?
