Seven decades of groundbreaking natural history
Sir David Attenborough has spent over 70 years educating and inspiring audiences through pioneering wildlife documentaries. As he turns 100, a look back at the programmes that redefined television natural history-and where to watch them in the UK.
Life on Earth: The series that changed everything
In 1979, Life on Earth became Attenborough's first attempt to chronicle the entire story of life, from primitive cells to modern ecosystems. The series sent camera crews across the globe to film animal behaviour in the wild, a first for television.
Dr Jean-Baptiste Gouyon, author of BBC Wildlife Documentaries in the Age of Attenborough, calls it "absolutely groundbreaking." For the first time, Attenborough appeared on location, speaking directly to viewers rather than narrating from a studio. The series also featured his iconic encounter with mountain gorillas, which he later described as one of his most thrilling experiences.
Broadcast to an estimated 500 million people worldwide, Life on Earth set the template for Attenborough's later Life Collection, including The Living Planet and The Private Life of Plants. A new BBC documentary, Making Life on Earth: Attenborough's Greatest Adventure, revisits its creation for his centenary.
Revealing the unseen: From chimpanzees to killer whales
The Trials of Life (1990) captured animal behaviour from birth to death, collaborating with scientists to uncover never-before-seen moments. The series filmed chimpanzees using tools and hunting colobus monkeys-footage that shocked viewers and sparked scientific debate.
The Blue Planet (2001) offered the first comprehensive look at ocean life, from deep-sea creatures to killer whales attacking a grey whale calf. Its 2017 sequel, Blue Planet II, exposed the devastating impact of plastic pollution, with Attenborough calling it a "crime" against marine life. Filmed across 64 countries over five years, it became the BBC's most expensive nature series.
Dr Gouyon notes that Blue Planet and Planet Earth (2006) rekindled public fascination with nature documentaries through cinematic storytelling. Planet Earth II (2016) drew younger audiences with dramatic sequences like snakes chasing iguanas, outperforming The X Factor in ratings.
Climate warnings and technological leaps
Frozen Planet (2011) highlighted climate change's impact on polar regions, featuring a minke whale's desperate escape from killer whales. Attenborough's closing speech in On Thin Ice warned of shrinking glaciers. The 2022 sequel used racer drones to film avalanches and showed golden eagles hunting mountain goats, delivering an even starker climate message.
Our Planet (2019), Attenborough's Netflix debut, focused entirely on conservation. Narrated by Penélope Cruz and Salma Hayek in Spanish-language regions, it reached 100 million households. BBC critic Will Gompertz praised its "dazzling images" and Attenborough's urgent call to protect the planet.
Finally turning the lens on Britain
At 94, Attenborough broke a decades-old BBC agreement to avoid filming in the UK, citing its "astonishing scenery" and "extraordinary wildlife." Wild Isles (2023) showcased British species, from white-tailed eagles catching geese mid-air to Scottish salmon leaping waterfalls. Attenborough even climbed 87 steps to a Welsh puffin colony, accompanied by a doctor and defibrillator.
Wild London (2026) explored the capital's urban wildlife, including foxes, while Secret Garden revealed the hidden dramas of UK gardens-like a duck protecting ducklings from an otter. Producer Bill Markham said Attenborough's influence could inspire more wildlife-friendly gardening.
A century of conservation and legacy
At 100, Attenborough's latest project, Ocean (2025), calls the sea "humanity's greatest ally against climate catastrophe." He argues that saving marine ecosystems is critical to preserving the planet.
His Netflix film Gorilla (2026) revisits his 1970s encounter with mountain gorillas, tracking their descendants' struggles. Directed by Oscar winner James Reed and produced with Leonardo DiCaprio, The Guardian called it "awe-inspiring."
"If we save the sea, we save our world."
