What happened when 16-year-old climate activist Greta Thunberg met 93-year-old natural historian Sir David Attenborough? Well, for starters, they talked about activism.

In a Skype conversation broadcast on BBC Radio 4 Today, Thunberg credited Attenborough's documentaries as the reason she became interested in climate change. The veteran filmmaker commended the teen activist for getting the world's attention on the global climate emergency — leading a 4-million strong climate march is just one example.

"She's achieved things that many of us who have been working on it for 20 odd years have failed to achieve. That is you have aroused the world. I'm very grateful to you. We all are, really," Attenborough said.

"I think everyone is grateful for you, for taking on the climate crisis and on the environmental crisis," Thunberg replied. "I hope you understand how much difference you have made and that we are all very thankful for that. So thank you. And thank you for dedicating your life to this."
