Countless insects and reptiles play a more vital role in ecosystem stability than most people realize—or even bother to think about. “Many plants and animals provide food, fibers, and building materials, as well as new medicines,” notes author David Hosansky. “Even tiny creatures such as insects, regarded by many as pests, are probably essential for the survival of Homo sapiens by filling critical niches in the global ecosystem.” Moreover, it’s not only insects, reptiles, or birds that are in trouble; many of our genetic cousins, the primates, are dropping in numbers at a dangerous rate.
