Bruce Willis is considering moving himself and his family out of Los Angeles because he is sick of the "toxic" air pollution there. Willis is concerned about the health of his kids with ex-wife Demi Moore. He says, "I happen to live in Los Angeles and it is probably one of the most toxic environments on Earth. "People live here and they know that the air is poisonous. They know that children are affected by the air in Los Angeles. "They say that growing up in Los Angeles is the equivalent of smoking a pack and a half of cigarettes throughout your entire childhood. "It's horrific when you can actually look at the air and see it."
