From the Publisher: A century after the birth of Rachel Carson, the world faces a new environmental disaster, from a chemical similar to DDT. This time the culprit appears to be IMD, or imidacloprid, a relatively new but widely used insecticide in the United States. Many beekeepers and researchers blame IMD for Colony Collapse Disorder, which has wiped out 23% of America's beehives. Even trace amounts make bees unable to fly back to their hive. Since honeybees are essential to the production of most major food crops, their demise could spell catastrophe. In a riveting, scientific/political detective story, Michael Schacker examines the evidence and offers a plan to save the bees. Like An Inconvenient Truth and Silent Spring, A Spring without Bees is both a powerful cautionary tale and a call to action.
