Through the widespread use of neonicotinoid pesticides we are killing the underpinning of the food chain

Neonicotinoids are the most widely used insecticides in the world. They've been linked to the decline of honeybees. But scientists now say they also harm many terrestrial, aquatic, and marine invertebrates. They damage sea urchin DNA, suppress the immune systems of crabs, and affect the tunneling and reproductive behavior of earthworms. They kill off the insects that many birds, amphibians, and reptiles rely on for food. According to Scott Hoffman Black, Executive Director of the Xerces Society, through the widespread use of these pesticides "we are killing the underpinning of the food chain."
