There is a large population of hunters that are about to move out of their prime hunting age. Many of them are Baby Boomers and getting too old go out into the woods. When they stop hunting the money they contributed to conservation will also decline.
Contrary to popular opinion hunting is good for the environment. People who hunt are often very concerned about the environment, donate to wildlife programs and protect their habitat. Enjoyment of the atmosphere comes with a concern over pollution and habitat destruction.
Hunting is very regulated today and requires people to buy licenses that are worth much more than the price of the meat. Yet they do it to get outdoors and engage in the sport. Loosing their money will mean we will need to fund conservation from other areas.
Some argue that the amount of hunters will drop 30% in the next few years.
