We found strong evidence linking biodiversity with production of ecosystem services and between nature exposure and human health, but many of these studies were limited in rigor and often only correlative. Much less in formation
is available to link biodiversity and health. However,some robust studies indicate that exposure to microbial biodiversity can improve health,specifically in reducing certain allergic and respiratory diseases. Overall,much more research is needed on mechanisms of causation.Also needed are a re-envisioning of land-use planning that places human well-being at the center and a new coalition of
ecologists, health and social scientists and planners to conduct research and develop policies that
promote human interaction with nature and biodiversity . Improvements in these areas should enhance human health and ecosystem,community,as well as human resilience.
