All across the world, irreplaceable habitats are under threat. Unique ecosystems of plants and animals are being destroyed by human activies. From the tiny to the vast, from prairie to meadow, and from Kent to Hungary, America to India, they are disappearing.

Irreplaceable captures the haunting beauty of these landscapes, including the rare species that call them home. And it reveals the human communities which form around these special places - from grassroots campaigners to professional conservationists and academics - committed to saving them from extinction. Ultimately it asks what a deep emotional connection to the land might offer us, and why we must fight for its continued survival.
