Four factors—the loss and fragmentation of habitat, the degradation of remaining habitat, pesticide poisoning, and the spread of diseases and parasites—account for most of the declines in populations of bees and other pollinators. These factors have complex political, economic, and social origins that are not easily addressed. At the local level, however, the solutions to many of these problems are simple and straightforward. Many insects are fairly resilient, and there are actions we can take in our own backyards and neighborhoods, on farms and ranches, and in city parks and wild areas, to help strengthen and support pollinator populations.
