All of the things you mentioned are less per capita in the city than in the country side. Agrarian living gives the impression of less environmental impact because the impact is more spread out. Outside the cities those lumper trucks are each replaced with many dozens of SUVs or pickup trucks when every family does the distribution themselves from the supermarkets. Just saying.

And the reason it is more expensive to live in a city is because more people find it more attractive to live there. That, and that fuel is subsidised and agrarian roads are disproportionally paid by taxpayers.
