“And it was really giving me real positivity, real hope that we’re doing this, and look, communities are thriving, but also the wildlife are thriving.
“And I get home, and I read the newspapers and I see articles and I talk to people, and the doom and gloom starts to set in more about the sort of bigger picture.
“And that contrast between some of the amazing things that are going on the ground versus the narrative and the general feeling amongst most people, that sort of contrast really bothered me.
“I thought, ‘come on, how do we… if we’re gonna get anywhere here, there’s a lot of amazing people who’ve been doing this a lot longer than I’ve been talking about climate change.
“How do we get their voices heard more? How do we inspire people to say we can fix this?’
“So the Earthshot Prize came out and evolved slowly from that.”

“She’s given me a lot of hope that this can happen, and I believe it and I’m seeing it with my own eyes—it’s everyone doing their bit, and helping and supporting what we’re trying to do, it’s all of us in it together.
