We play when we're kids to try new things and learn how the world works, and when we think no-one's looking we do it as adults too. Play's  important for our development and so you should probably do it or you'll turn out a wrong'un. But Dave's guest today says play is also a way to smash the Very Serious Rules of how to think about climate change - rules the following of which demonstrably are not working.  If play = creativity, and creativity = necessary, is it time to lark about more in the name of saving the planet? Joining Dave this episode is Lucy Hawthorne. She's a creativity facilitator who uses Lego - yes, Lego - to teach adults a thing or two about how to think sideways about climate change and what to do about it. She even sent some in the post to Dave.  Find Lucy at Catalysts Club and Climate Play.  Owl noise: Find out more about Stuart Brown's eight categories of play.
