FRONTLINE "Poisoned Waters"

NOT RECOMMENDED FOR DIAL UP

In this clip from "Poisoned Waters," correspondent Hedrick Smith examines the impact of large-scale factory farms, a major source of pollution to US waterways. Industrial scale chicken farms generate 1.5 billion pounds of waste annually—more than the human waste from New York, Washington, San Francisco and Atlanta combined. Watch on air and online beginning Tues, Apr 21 on PBS (check local listings).
