At the moment I am daydreaming about inventing something exceptionordinarily good that could change the world for the better, because of all the things, it’s the better that’s needed. And if you are thinking I'm too small to make a difference then remember the plankton – they are one of the tiniest creatures on the planet but without them where would we be? Probably living on Mars. The utterly wonderful Clarice Bean is thinking about the endangered things: the big creatures, the little creatures, the plants and the trees.

But it’s not just the planet that needs help – there’s her whole family too . . .
