You’ve probably grown up hearing his unmistakable voice in some of your favourite nature documentaries…we’re of course talking about Sir David Attenborough, who turns 100 this Friday. He’s been making wildlife films for more than 70 years, turning nature documentaries into must-see TV and inspiring people all over the world to learn more about the wonders of our planet.

But he hasn’t just changed the way we see the natural world - he’s also alerted us to how rapidly it’s changing because of climate change, and has influenced policy and public perceptions in the process.

In this episode, we look back at some of his most iconic moments. Our climate and science correspondent, Georgina Rannard, tells us how he’s changed the world - and we hear how he’s inspired lots of you to take action on climate change.
