Return of the Wilderness to the UK?

[Devonian]

If you want to know what it would be like without us around google Chernobyl or Fukushima exclusion zone. Even 28 years on it doesn't look anything like a true wilderness.

Exactly!!

All this talk of "Wilderness" is just pie in the sky and has no real relevance to the UK given our environment; climate; geology; flora and fauna.
