In light of recent events and films such as "An Inconvenient Truth," the general population would agree that it is important to maintain a certain portion of the natural world. No matter how big the Earth's population gets, no matter how many buildings and streets we need to build, it is important to conserve those natural landscapes. The main reason to keep the natural areas in existence is that they contribute to the overall health of the Earth.
Though it may seem odd to an animal rights activist who may have a preconceived notion that hunters do not appreciate natural habitats, hunters actually do act as good checks and balances for these habitats.
First of all, hunters ensure that there are enough animals inhabiting an area where they want to hunt. With the passage of endangered animal protection laws, everyone, including hunters, understands that it is not good for the natural cycle of the world to deplete a species. Hunters know that it is important to keep numbers up enough so that there is a healthy flow in the food chain. Every animal depends on every other living thing, from plant to larger animals. Hunters donate money, through hunting licenses and gifts in kind donations, to projects that maintain habitats [source: Free-Eco.org].
Another check that hunters provide is to make sure populations of animals do not get too large. Deer is a well-known species that seems to overpopulate certain areas of the country, and the sport of hunting is an effective check against that overpopulation. Though the root of the overpopulation problem can be traced back to humans, since we have eliminated the deer's natural predators, hunting is a good replacement check.
It's important to keep in mind, also, that some hunters do make a living or at least supplement their lives off of the sport of hunting. By conserving hunting habitats, we are helping maintain the livelihoods of some men and women.
