Although concerns over the ecological impacts of pesticides gave rise to the environmental movement of the late 1960s and 1970s, since that time, pesticide use and its effects have been largely ignored by the law and by legal scholars. This book addresses this omission by providing a unique and serious treatment of the significance of pesticide issues in environmental law and takes an ecological perspective on the legal issues. Dealing with a wide range of questions relating to pests and pesticides, the book focuses primarily on agricultural pesticide use as the largest contaminator in the US. It also examines the legacy of past pesticide use and analyzes how recent developments in ecological science can inform the law and increase our understanding of ecology. Interdisciplinary in its approach, the book will be of interest to academics, lawyers, scientists and environmental and agricultural professionals.
