They have a whole website devoted to faux-environmentalists who want to preserve nature so they have something to kill.
http://www.sierrasportsmen.org/The section on indoctrinating one's kids into animal abuse and gun culture is especially disturbing.
http://www.sierrasportsmen.org/sierrasportsmen/sportskids/The funny thing is, their own policy admits that hunting is antithetical to maintaining a natural landscape: "Because national parks are set aside for the preservation of natural landscapes and wildlife, the Sierra Club is opposed to sport hunting in national parks." Makes sense. After all, nature is self-balancing without need for human intervention, and interference only leads to further destabilization.
But the preceding sentences say the opposite. "Wildlife and Native Plant Management, Sport Hunting And Fishing - Wildlife and native plant management should emphasize maintenance and restoration of healthy, viable native plant and animal populations, their habitats, and ecological processes. Acceptable management approaches include both regulated periodic hunting and fishing when based on sufficient scientifically valid biological data and when consistent with all other management purposes and when necessary total protection of particular species or populations."
http://www.sierrasportsmen.org/sierrasportsmen/policy.aspIf national parks can maintain ecological balance without hunting, why is it necessary to manage nature by killing off animals for sport outside the borders of those parks? This is either cognitive dissonance sufficient to warrant mental health concerns, or shocking dishonesty. In either case, the Sierra Club deserves neither the money nor the support of those who care about the earth.
