Human microbiomes are made up on the microbes—bacteria, viruses, fungi and archaea-that are interacting in, on and around our bodies. Jessica Lee Green, a nuclear engineer, microbiologist and environmental scientist, explains that neighborhoods and buildings have microbiomes too. Scientists are learning more about how microbiomes interact and how they impact health. They're also finding microbial diversity is healthiest. Dr. Green believes that in the next decade people will be able to onsider microbiomes of neighborhoods and buildings when they decide where to live, work and send their kids to school.
