A bill before the House of Representatives would drasically alter the way polar bears and other wildlife species are protected in the United States.

H.R. 4089 (The "Sportsmen's Heritage Act of 2012") combines several anti-wildlife proposals into a single dangerous bill.

It amends the Marine Mammal Protection Act (MMPA) to allow for the importation of polar bear "trophies" from Canada that are presented as having been taken prior to the May 2008 Endangered Species Act listing.

It requires federal agencies to open nearly all public lands to hunting--including national parks--and prevents federal agencies from reviewing the impacts of hunting on non-tartget species or their habitats under the National Environmental Policy Act.

It removes the ability of the EPA to protect wildlife and people from lead poisoning through toxic ammunition exposure.
