Jenn D, you are corect that there are resons to hunt. It is a population control tool. Man has hunted since the begining of man to feed his family. I realize nowadays you don't need to hunt to eat, but if there were no hunters, there would be an over abundance of animals. Take deer for example, you see how many cars hit deer every year, just imagine if there was no hunters, there would be a lot more crashes every year.
I worked with metro Canada Geese in MN for 3 years. Because there isn't a hunting season in the metropolitan area, the goose population has increased by thousands, most of these geese will migrate to the airport in the late summer/early fall causing a flight safety issue. These are 2 examples. Hunting is a form of population control and also is healthy (to a point) for the population of the animal as it lowers the disease spread through the herd.
Also Jenn, I do agree there are people that go out there to kill, these are not hunters. A true hunter will tell you they don't need to kill an animal everytime they go out. I will not hunt anything I will not eat. I personally don't like venison so I won't hunt deer, but I have no problem with deer hunters.
Also note that this bear was not hunted, it was hit w/ a combine while working the farmer's field.
