ANCHORAGE, Alaska (AP) - Alaska wolves are the subject of an advertising campaign in a busy Washington, D.C. subway station.
Defenders of Wildlife bought the wall posters to promote federal legislation in a push to end aerial killing of wolves.
Predator control has been used to increase moose and caribou populations.
Defenders of Wildlife spokeswoman Jessica Brand says Alaskans voted twice to ban aerial hunting and the vote has been overturned twice.
She says the only way to end the practice is to close a loophole in federal legislation.
Defenders of Wildlife says shooting wolves from airplanes is inhumane and violates the concept of fair chase.
Alaska Congressman Don Young opposes the national legislation.
He says it infringes on the ability of individual states to control wildlife populations.
And he says some predator control is necessary to keep the Alaska wolf population in check so they do not devour moose and caribou available to Native villagers who depend on game for survival.
