Many of us may have wished that mosquitoes or flies would just disappear forever, yet as entomologist Dave Goulson cautions, "If we lose the insects, then everything is going to collapse." Drawing on 30 years of research, Goulson offers an accessible, fascinating book that examines the evidence of an alarming drop in insect numbers around the world—notably, honeybees and monarch butterflies—caused by the indiscriminate use of chemical pesticides. Humanity's food supply is threatened, and so here Goulson lays out suggestions for how to avert a looming ecological disaster of our own making.
