what do you say to your children about this? i think they're living and growing up in a world where it's much more talked about than when we were growing up, so that has benefits and that has negatives as well. because we are seeing a rise in climate anxiety. young people now are growing up where their futures are basically being threatened the whole time. it's very unnerving and it's very anxiety—making. and i suppose, going in the other direction, your dad has been worried about this stuff for a very long time. and actually, people used to sort of take the mickey out of him a little bit for it. it's been a hard road for him. my grandfather started off helping out wwf a long time ago with its nature work and biodiversity, and i think that my father's progressed that on and talked about climate change a lot more — very early on, before anyone else thought it was a topic. so, yes, he's had a really rough ride on that, and i think he's been proven to be well ahead
