Sue Nelson and Alice Hope explore the numbers behind nature and pick apart the jargon and misinformation surrounding climate, the environment and biodiversity. Each month, they start with a number and investigate what it really means. From net zero to hedgerows, worms to water, Sue and Alice aren’t afraid to get their feet muddy in the quest for facts.
