Evocative storytelling and beautiful art present the true story of how reintroducing wolves into Yellowstone Park saved its ecosystem.When wolves disappeared from Yellowstone Park in the 1930s, the ecosystem started to collapse. Enormous herds of elk swarmed the plains, bears starved, rabbit families shrunk and birds flew away to new homes. Plants vanished, trees withered and rivers meandered.Until in 1995, wolves were reintroduced to the park and everything began to change for the better. This is the story of their homecoming.Engaging, fascinating and hopeful, this book shows that human actions can make a difference―because every creature plays a part in the fight against the environmental crisis.
