Have to push back on the "people shoved into cities" narrative. It just sounds like the conspiracy theories around "15 minutes cities" all over again.
An example of rewilding on its wikipedia page is "wildlife-friendly overpasses and underpasses". That's literally going the "making areas more friendly to wildlife" route.
When it comes to 15-minute cities there's all these conspiracies, but then you look behind it and it's just about allowing economic liberty to build taller and allow more commercial uses like doctors, daycares, and corner stores in residential neighborhoods, and restrict free government subsidized street parking.
It's good to be viligant, okay? And if any policies come up that are shoving people into cities, feel free to protest. But until then, a lot of the policies are actually exactly the "being more friendly to wildlife" that you're asking for and not shoving people into cities.
