Fish and Wildlife Service conducts every five years, fewer people are hunting, even as population rises. National Public Radio reported, a graph shows 2016 statistics, that only about 5 percent of Americans, 16 years old and older, actually hunt, which is half of what it was 50 years ago. The decline in popularity of hunting is expected to accelerate over the next decade, which threatens how US will pay for conservation. Controversy Trophy hunting is most often criticised when it involves rare or endangered animals. Opponents may also see trophy hunting as an issue of morality or animal cruelty, criticising the killing of living creatures for recreation. Victorian era dramatist W. S. Gilbert remarked, "Deer-stalking would be a very fine sport if only the deer had guns." There is also debate about the extent to which trophy hunting benefits the local economy. Hunters pay substantial fees to the game outfitters and hunting guides which contributes to the local economy and provides value to animals that would otherwise be seen as competition for grazing, livestock, and crops. However, the argument is disputed by animal welfare organizations and other opponents of trophy hunting. It is argued that the animals are worth more to the community for ecotourism than hunting. Economics A variety of industries benefit from hunting and support hunting on economic grounds. In Tanzania, it is estimated that a safari hunter spends fifty to one hundred times that of the average ecotourist. While the average photo tourist may seek luxury accommodation, the average safari hunter generally stays in tented camps. Safari hunters are also more likely to use remote areas, uninviting to the typical ecotourist. Advocates argue that these hunters allow for anti-poaching activities and revenue for local communities. In the United Kingdom, the game hunting of birds as an industry is said to be extremely important to the rural economy. The Cobham Report of 1997 suggested it to be worth around £700 million, and hunting and shooting lobby groups claimed it to be worth over a billion pounds less than ten years later. Hunting also has a significant financial impact in the United States, with many companies specialising in hunting equipment or speciality tourism. Many different technologies have been created to assist hunters. Today's hunters come from a broad range of economic, social, and cultural backgrounds. In 2001, over thirteen million hunters averaged eighteen days hunting, and spent over $20.5
