I would add that city people underestimate or simply do not know about the ability of vegetation to cool off its environment. My city has areas (few abandoned plots) with a wild high grass and bushes on them. When it’s hot and you walk nearby, like 2-3m close, it is as if you went from the street to under AC. I don’t know how they do it, but my guess is that photosynthesis is a hell of an endothermic process. And you’re right, modern “city trimming” is just a disgusting non-functional nonsense.
