I wanted to address this first and with the most accurate attention.
The reason most nations you consider civilized have stopped hunting is that they have already destroyed so much of the natural habitat, that they do not have sustainable animal populations in the wild. These populations require asistance from man to survive. And those populations that do not require assistance from man, are almost invariably hunted. Hunting exists in Germany, the UK, and most other European nations.
In the US, we have maintained large tracts of wilderness. The animals there do what animals do. They eat and they breed. In Alabama alone the whitetail deer population is estimated at 1.5 million animals. Biologists say that one-third of those animals should be removed (culled, murdered, hunted - pick a word) in order to maintain a stable herd size.
Also, the extra taxes and fees paid by hunters and fishermen pay the lion's share of conservation efforts in the US. So hunters pay for the conservation and act as the only predator for many species, thereby controlling populations of many animals.
So, to review, most of the world has NOT grown out of such behavior. They just reserve it for the rich.
And secondly, the hunting here serves to actually protect the animals and their habitats.
Low, since you choose to be so condescending towards hunters, will you please bless us with your wisdom on how to control populations of wild animals without hunting?
