Who better to close the series than the one and only, Chris Packham CBE?

Chris is a world-renowned naturalist, campaigner, broadcaster and science communicator. He makes waves across the conservation sector for championing the natural world, and we couldn't think of a better guest to help us understand the big stuff: beavers, biodiversity, climate - and the road ahead.

Also coming up: Producer Emma makes an appearance as judge to deliver overall series winners of the #FactOff and the QUIZ.
