With vivid, observant reporting, veteran environmental journalist Fred Pearce transports listeners to the remote cloud forests of Ecuador, the remains of a forest civilization in Nigeria, a mystifying mountain peak in the middle of the Atlantic Ocean, and the boreal forests of western Canada and the United States, where devastating wildfires are linked to suppressing the natural fire cycles of forests and the maintenance practices of Indigenous peoples.

Throughout the book, Pearce interviews the people who traditionally live in forests. He speaks to Indigenous peoples in western Canada and the United States who are fighting to control their traditional forested lands and manage them according to their traditional practices. He visits and speaks with Nepalese hill dwellers, Kenyan farmers, and West African sawyers who show him that forests are as much human landscapes as they are natural paradises. The lives of humans are now imprinted in forest ecology.

At the heart of Pearce's investigation is a provocative argument: planting more trees isn't the answer to declining forests. If given room and left to their own devices, forests and the people who live in them will fight back to restore their own domain.
