David Attenborough: A Life on Our Planet is a 2020 British documentary film narrated by David Attenborough and produced and directed by Jonnie Hughes. The film acts as a "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. It was released on Netflix on 4 October 2020, along with a companion book A Life on Our Planet. Synopsis From Pripyat, a deserted area after the nuclear disaster, Attenborough gives an overview of his life. Interspersed with footage of his career and of a wide variety of ecosystems, he narrates key moments in his career and indicators of how the planet has changed since he was born in 1926. As a child, Attenborough enjoyed studying fossils. His documentary career began in the 1950s when he began working for the BBC, a British public service broadcaster. He visited places such as the African Serengeti, in which native animals require vast areas of land to maintain grazing patterns. Over time, he noticed a decline in wildlife when searching for fish or orangutans in Borneo or other animals which he was looking for as part of his documentaries. Areas of the Arctic or Antarctic were different to what the filming crew expected due to ice caps melting. The causes are anthropogenic climate change and biodiversity loss pushing the planet towards a sixth mass extinction event over a period of centuries rather than the hundreds of millennia that built up to previous mass extinctions. Attenborough describes the film as his "witness statement" and gives an impression of what could happen to the planet over the course of a lifetime beginning in 2020 and lasting as long as his own, were human activity to continue unchanged. The Amazon rainforest could degrade into a savanna; the Arctic could lose all ice during summer; coral reefs could die; soil overuse could cause food crises. These irreversible events would cause mass extinction and exacerbate climate change further. However, Attenborough describes actions which could prevent these effects and combat climate change and biodiversity loss. He asserts that the solution has been "staring us in the face all along. To restore stability to our planet, we must restore its biodiversity. The very thing that we've removed." He proposes re-wilding; moreover, he says that bringing countries out of poverty, providing universal healthcare and
