For the last three billion years or so, life on Earth has been shaped by natural forces. Through climate change, humans have now affected even the most remote environments and their inhabitants, and studies suggest that through our actions we are forcing some animals to evolve at breakneck speed to survive. Whilst some are thriving, others are on the brink of extinction, and for others the only option is life in captivity. Today, it's not just the fittest that survive; sometimes it's the ones we decide to let live. In this book, Helen Pilcher considers the many ways that we've shaped the DNA of the animal kingdom and in so doing, altered the fate of life on earth. In her post-natural history guide, she invites us to meet key species that have been sculpted by humanity, as well as the researchers and conservationists who create, manage and tend to these post-natural creations.
