In my city, city planners decided to bring trees that aren't native to our country (sycamore trees), and now we have an invasion of these bugs that bite and stink bugs.
It's bog standard to have fruit trees and berry bushes in urban areas here in sweden, rowan trees and serviceberry bushes are literally everywhere, and it simply is not a problem. Birds will eat most of it before you even have time to notice the fruit going bad.
Oh I'm sure some European countries have a more ecologically friendly setup than us. I'm speaking from the perspective of US city planners, and I assure you, this is a major consideration for them.
