Fewer bats-->more insecticides-->higher infant mortality

County-level insecticide use and infant mortality due to internal causes both increased after the emergence of white-nose syndrome, whereas farms’ crop revenue decreased. This study provides an example of how biodiversity loss affects human well-being and presents observational methods for quantifying those costs.  

It makes sense, but it's good to see it in a respected science journal.
