I have killed 8 deer this year, 7 have been does...

Why do I look at it as "necessary"...I hunt my own land, 850 acres, and we farm...So far we have killed 37 deer off these farms this year...When you raise soybeans, corn, wheat and peanuts you see how much deer can eat...I also eat deer, if I didn't eat deer, don't really know if I would kill them....
