BOOTHBAY HARBOR, Maine (AP) -- Republican lawmakers are targeting one of the U.S.'s longest standing pieces of environmental legislation, credited with helping save rare whales from extinction.

Conservative leaders feel they now have the political will to remove key pieces of the Marine Mammal Protection Act, enacted in 1972 to protect whales, seals, polar bears and other sea animals. The law also places restrictions on commercial fishermen, shippers and other marine industries.
