In 2015, there were approximately 35 million hunting licenses, tags, permits, and stamps sold in the United States at a cumulative cost of $821 million. The great bulk of this money went to conservation, in one form or another.

It is true that approximately one-quarter of the average state wildlife agency’s budget comes from federal funding. However, this funding is almost entirely provided by the Pittman-Robertson Act (Federal Aid in Wildlife Restoration Act of 1937), which imposes an 11 percent excise tax on the sale of firearms and ammunition products. Since 1939, $10.1 billion of these tax dollars has been awarded to states in support of conservation initiatives. When combined with contributions derived from angler taxes via the dedicated Dingell-Johnson Act of 1950 and the Wallop-Breaux Amendment of 1984, this number increases to an impressive $18 billion dollars in direct funding for state conservation efforts. Can anyone name any other source of conservation dollars that even approaches this?

You hunt because you think it is fun, not because you feel you have some "moral obligation". It just happens to also be necessary due to people who thought the same as you not being properly controlled by a government to not destroy the ecosystem.

And when did humans suddenly leave the ecosystem? We're just as much part of it as any wolf or deer
