LYNDHURST, N.J. -- Just 5 miles from Manhattan, the New Jersey Meadowlands are famous as the home of New York's two pro football teams, a venue for hockey and basketball, and Bruce Springsteen stadium concerts. They're also infamous for toxic pollution and several sprawling dumps that destroyed tidal wetlands that some have compared to the Florida Everglades and cemented New Jersey's reputation as an industrial wasteland. But there is a chance that the Meadowlands may yet be famous for a near-miraculous ecological revival. The marshes here are rebounding. And the Meadowlands' liquid heart, the Hackensack River -- long treated as little more than an open sewer -- is stirring again with aquatic life.
