A Life On Our Planet is a documentary film narrated by David Attenborough, a BBC broadcaster that goes on to trace his more than 60-year career as a naturalist, and his concern about the future of our planet if we continue to act the same way.

David Attenborough is now 94 years old, and has visited every continent on the globe, exploring the wild places of our planet and documenting the living world in all its variety and wonder. He calls the film as his "witness statement", through which Attenborough shares first-hand his concern for the current state of the planet due to humanity’s impact on nature and his hopes for the future. In this moving documentary, the famed naturalist maps how steeply the planet’s biodiversity has diminished over his lifetime. He seems tired of keeping quiet about it. The scale of the problem is overwhelming, that it can be difficult to absorb, but he offers a solution and vision of the future if we act now.
