I don't live there, but this attitude won't make you any friends.
>We all share this world.
Yes, tell me how me and you and Bezos and Musk are all equally sharing the world. We're all in this together and you care so much about the pollution of other peoples' small towns. That's why there's nice neighborhoods and not so nice neighbourhoods, nice areas to live in and not so nice areas to live in. Because some people have to deal with the pollution so that you can live in nice neighborhoods without any pollution while still enjoying all the luxuries of modern society that generate pollution except not in your back yard.
>My car would emit about 5 tonnes of CO2 over about 15k miles(2L hatchback).
And where was that car manufactured? In your back yard or in some industrial town with more pollution? Do you oppose car factories there too?
