Nature surrounds us, but as our cities and urban environments encroach ever further across green spaces, are we losing one of the most powerful weapons in our armory against disease?
In this excerpt from her new book "Good Nature," Kathy Willis, professor of biodiversity at the University of Oxford, shows how satellite images reveal the negative effect that the erosion of green spaces is having on the mental wellbeing of the population. It's also increasing the risk of respiratory and cardiovascular diseases. She explores the tools we use to make these discoveries, and reveals the untapped power of nature in combating common health problems.
