This witty animation from the Netherlands shows exactly the effects of urban expansion - and there are even earthworms (and a badger).

Subject: [Annelida] The earthworm dilemma
Well, I suspect this would only be an important effect if there are more earthworms on the planet now than pre-climate change. Whereas, while there is some expansion into former glaciated lands in N America, humankind otherwise has sealed off much former good worm habitat with millions of hectares of worm-proof structures via urbanisation and roading.
