In our monthly podcast, Counting the Earth, award-winning science journalist Sue Nelson and UKCEH’s Alice Hope explore the numbers behind nature, picking apart the statistics surrounding climate and biodiversity, and tallying up the contributions that the natural world makes to our lives.

Each episode starts with a number and then delves into what it really means – from the zero in net zero and the vital statistics of earthworms – to the ideal length of hedgerow to support biodiversity and store carbon.
