How Wolves Change Rivers (2014)

Plot

The reintroduction of wolves to Yellowstone National Park, after a 70-year absence, sparked an extraordinary ecological phenomenon known as a "trophic cascade." George Monbiot delves into the intricate ways these predators impact their environment, particularly how their presence influences river ecosystems. By controlling herbivore populations, wolves help restore balance, leading to healthier vegetation and revitalized waterways. Monbiot's exploration reveals the profound interconnectedness of nature and highlights the wolves’ crucial role in shaping the landscape and promoting biodiversity within the park.
