Not sure about your second point. Let’s consider an oversimplifying example where population is homogenous in an area/nation. If 50% of the land is unpleasant, then 50% of the population will live next to unpleasant stuff. If only 20% is unpleasant, 20% will love, saving 30% of the population.

Managing a landfill/sewage plant can be worthwhile.
