Part 10/15:
Crowe explains how introduced species—such as cane toads, foxes, feral cats, and wild horses (mustangs in the US)—disrupt fragile ecological balances. His stories about cane toads, introduced to control pests but now numbering in hundreds of millions, highlight the unintended consequences of ecological meddling. Similarly, crow discusses wolf reintroduction in Montana’s Yellowstone, a case illustrating how apex predators regulate herbivore populations like elk, which, in overabundance, threaten the landscape. These examples underscore the complex choreography required to maintain a healthy ecosystem.
