I vividly remember sitting in my biology class at school in 1979, eyes completely glued to the screen as we watched Life on Earth. I had never seen nature portrayed in such a breathtaking, cinematic way before. It was an absolute revelation.
I wasn’t alone in feeling that magic. As the BBC notes, Life on Earth was “the series that started it all,” tracing the history of nature back billions of years to its very beginnings. It changed the way we viewed our world forever.
Today, as Sir David Attenborough celebrates his monumental 100th birthday, the world is pausing to honour his extraordinary life and legacy. But for me, I think the absolute best way we can celebrate his centenary is to step outside and do something for the planet. Whether it’s planting a tree, supporting a conservation group, or simply changing a daily habit, it’s exactly what he would want—and it’s good for us collectively, too.
The globe is already buzzing with tributes. The BBC is rolling out a dedicated week of programming and a spectacular live concert at the Royal Albert Hall. Beyond the screen, his legacy is being honoured through coordinated nature walks, museum exhibitions, and widespread global conservation initiatives.
It is a fitting tribute to a man whose achievements are staggering. Sir David is the only person in history to win BAFTA Awards for programs shot in black-and-white, colour, HD, 3D, and 4K. Furthermore, his name is literally woven into the fabric of the planet, with over 40 living and extinct species named in his honour. (For a deeper dive into how his storytelling evolved alongside broadcasting technology and inspired leading scientists, you can read my full feature over on our sister site, Women Love Tech).
Ultimately, Sir David’s most enduring legacy isn’t just showing us the beauty of the world, but urging us to protect it.
To inspire your own planetary action today, here are three of his most fabulous and urgent quotes on why making a positive impact is so vital:
“The truth is: the natural world is changing. And we are totally dependent on that world. It provides our food, water and air. It is the most precious thing we have and we need to defend it.”
“Surely we all have a responsibility to care for our Blue Planet. The future of humanity and indeed, all life on earth, now depends on us.”
“What we do in the next few years will profoundly affect the next few thousand years.”
