David Attenborough's Life on Our Planet will be published this autumn and is the natural historian's witness statement on the present and future.

"The Earth's life-support machine, the thing we humans rely upon for everything we need, runs on its biodiversity," said Attenborough, the legendary natural history presenter and environmental activist, as news of his forthcoming book is released.

"Yet the way we live on Earth now is sending it into a decline," he said. "This book contains my witness statement, and my vision for the future - the story of how we came to make this, our greatest mistake, and how, if we act now, we can yet put it right.'

The much-anticipated Life on Our Planet: My Witness Statement and Vision for the Future will be published this autumn. The work reflects on Attenborough’s remarkable career exploring and documenting the natural world, and the decline of the planet's environment and biodiversity which he has observed first-hand in that time.

The scholarly yet highly accessible work, to be published by Ebury, will also present Attenborough's view on the future that lies ahead and how to avoid the worst that can happen.

"This book records some of the dreadful damage mankind has already wrought upon the natural world and the real and imminent danger that things could get much, much worse if we do not act now," says the veteran campaigner and broadcaster.

"But it is also a hopeful book: it offers a different future. It describes some of the ways in which we can begin to turn things around if only we all have the will to do so. Surely together we must now find that determination, and begin to make that change, for the sake of all the inhabitants of our planet."

Life on Our Planet will be released in October as a hardback, ebook and audiobook read by the author. Its publication will coincide with the global release of a Netflix documentary film of the same title, commissioned by the World Wildlife Fund.
