"Gives the reader a sense of lost New York, of the incredibly rich and biologically diverse ecosystem that once was the lower Hudson River estuary." -Ted Steinberg, author of Gotham Unbound
Heartbeats in the Muck traces the incredible arc of New York Harbor's environmental history. Once a pristine estuary bristling with oysters and striped bass and visited by sharks, porpoises, and seals, the harbor has been marked by centuries of rampant industrialization and degradation of its natural environment. Garbage dumping, oil spills, sewage sludge, pesticides, heavy metals, poisonous PCBs, landfills, and dredging greatly diminished life in the harbor, in some places to nil.
Now, forty years after the Clean Water Act began to resurrect New York Harbor, John Waldman delivers a new edition of his New York Society Library Award-winning book. Heartbeats in the Muck is a lively, accessible narrative of the animals, water quality, and habitats of the harbor. It includes captivating personal accounts of the author's explorations of its farthest and most noteworthy reaches, treating readers to an intimate environmental tour of a shad camp near the George Washington Bridge, the Arthur Kill (home of the resurgent heron colonies), the Hackensack Meadowlands, the darkness under a giant Manhattan pier, and the famously polluted Gowanus Canal. A new epilogue details some of the remarkable changes that have come upon New York Harbor in recent years.
"Full of humor and a picaresque joy in the almost absurd persistence of Gotham's underwater ecosystems, Heartbeats should be read by every urbanite who dreams of a better relationship with nature." -Paul Greenberg, New York Times-bestselling author of Four Fish: The Future of the Last Wild Food
