quinara | Cities vs Nature

Once upon a time a read a lecture summary or something on the Cambridge website about what would happen if humans upped and vanished one day from a large city (such as Cambridge)... I've never been able to find it again, but it stuck with me and was one of the main inspirations behind abridgement. And these images from Pripyat in the Chernobyl exclusion zone remind me of that too:

Can't get over that second image with the forest re-emerging between the buildings.
