Part 1 of the Urban Microbiome special: Our urban landscapes have become increasingly sanitized and less biodiverse. A building body of research that shows that this has led to a depletion of beneficial microbes and that, in turn, is having a negative effect on our health. The lack of exposure to microbes from an early age is thought to have a number of consequences for human health, such as an increase in allergies and autoimmune diseases. Guy Henderson visits Micropia, the world’s first microbe zoo in Amsterdam, to find out more about the importance of the invisible world that is all around us, and inside us. #RazorScienceShow @RAZOR Science Show
