That biodiversity means many Ebola treatment sites were literally hacked out of jungle. As a result, we were sharing space with new neighbors, many of whom had now lost their habitat and were in the market for a new home. Our sites were their dream homes. With our drainage canals, we would draw field mice, which would in turn draw snakes. Then with our lights, we would draw huge insects like moths and horn-beetles, one of which smacked me in the eye during flight. To my relief, neither of us seemed permanently harmed. And speaking of flight, once clouds of insects hovered around, dozens of birds would buzz in to feed. It felt very much like we were in a new biosphere with our own flora and fauna—mostly fauna.
