yes , but that doesn't make it right .... it's not natural that they are here in their millions because man created that problem by giving them a nice cosy environment, they need to be eliminated with poison or gas or whatever ..... but there must be 10,000,000 in Bangkok alone.
and if they didn't stop the fox hunts in the UK they wouldn't have a problem, and I'm sure there's not 1,000,000 bears making problem in Canada and Russia, and Tigers are encroaching into villages because their habitat is getting smaller and smaller.
