In fact deer are more and more numerous as time goes on. Rare or threatened animals are not allowed to be hunted.
Read a hunting regulation booklet, Sungirl. It talks about the ways in which you may legally harvest, what weapons you can use and where, how you cannot use artificial lights at night for most animals, how you cannot trespass, etc. etc...which animals are protected and which are not (but have very specifically formulated bag limits which serve to STRENGTHEN the population and give them room to reproduce without over stressing the food supply. It's when the PETA people get involved and object to hunting that the animals overrun the land's capacity to support them.
LOL!! SInce when do hunters obey the bag limits?? NOT where I came from ..Western New York. The Grounds dept where I worked would deliberately drive the state owned van into the deer grazing throughout the acres of grounds and pretend it was a car accident and the deers fault....they did this on the second shift of course and were hardly seen. THen I continually heard about the plans to get away with more deer than were allowed...all kinds of deceiptful plans.... THen there is this guy who just last year here in florida told me about his hunting fatherinlaw who said he was going hunting and was talking about getting the PROTECTED cougars...he said they were definetley coming home with one of those because "THERE AREN"T MANY OF THEM LEFT YA KNOW!!" TYPICAL! Have you been out in the real world?
