I love how hunters use the argument about having to kill deer to keep the population down. The problem with that is, we wouldn't have to do it if we hadn't killed the majority of their predators! Because humans are on the earth, nature is out of balance, so, we, as humans, feel we need to compensate somehow. I am veggie, but a realistic veggie. Because the damage is done, we DO need to fix it, so by getting hunting licenses (which we have to PAY for), we are protecting some of the other species. At least, in Michigan. I'm not justifying it, but hunting has now become a necessity here. The deer population is EXPLODING. If I was ever to eat meat again, I would eat what I hunted. At least it's not pumped with steroids or living miserably in a factory farm. I think the Native American's had it right...since I could not hunt my own food (by looking it in the eye and then killing it), I have no right to eat it. But everyone is different...that's just my opinion.
I'm writing an article on prairie dog colonies in urban areas, and brought up the "we hunt deer because we killed off the predators" bit to a PD advocate. She said all populations will reproduce more in reaction to a culling, making the problem worse!
No, not exactly. This is why culling has to be done by people who understand what they're doing. Shooting pregnant females sytematically leads to a population decrease, but shooting mature males has exactly the effect you say. It is true that females of most species become more fecund in response to pressure from predation, but not enough to compensate for a well-managed culling policy.
