Deer hunters.

A mate of mine has just been up Scotland shooting deers.Sounds bad, but when you investigate, it becomes clear.He told me some woman had given him some grief, saying it was wrong and cruel. She had clearly not done her research. The deer eat lots of vegitation, and they eat a lot. This affects the food chain, and stops other animals surviving, especially through the winter.
The problem started by lack of their natual hunters, the Wolves. 200 years without their natual preditors, the Deer has bred out of control. It's my understanding the brown bear has also gone. Before you make a fool of yourself, do some research, just sayin.
