Let's just forget the Balkan wars and follow the quote from my sig. Nobody won and everyone lost with those wars. For the fauna I've got no idea, try smth with google. The industrialisation isn't too bad and the country side is nice with clear air. There are some parts of rivers that are dirty and big cities are too obviously, but besides that not too much. Since Serbia ain't one of the most advanced countries industrialisation isn't as bad as in some other countries.
