Part memoir, part urgent call to action - it’s a quiet, powerful reflection from someone who’s spent a lifetime witnessing the beauty and wonder of the natural world. Framed by Attenborough’s signature calm voice, the film walks through the astonishing changes he’s seen over the decades: vibrant ecosystems vanishing, species disappearing, and the planet shifting under the weight of human activity. But it’s not all mourning. Attenborough offers us a hopeful path forward, one that’s still within reach. It’s one of the most heartbreaking yet optimistic perspectives I’ve seen on the subject.
