The demilitarized zone in Korea is also reported to be rich in wildlife, as is our own White Sands Missle Range, both because of the enforced exclusion of people. It's interesting to think about. There are more people all the time everywhere in the world except in a few places accidentally protected by terrible reasons.
P.S. Wormwood Forest is one of those books which we missed hearing about, and we hadn't ordered it until one of our library users asked for it. As much as possible we order what you ask for, and we count on you all to point out the titles we should have when you notice they are not yet in the system.
