"Forty years ago, in the enormously praised and fiercely criticized book, Silent Spring, Rachel Carson demonstrated the dangers of pesticides to humans and ecosystems and called for precaution in their use. Yet, the majority of environmental regulations passed since 1962 have primarily addressed pollutant discharge rather than cleaner products and technologies. The number of active ingredients in pesticides used in the United States has risen from 32 in 1939 to 860 in recent times, while the overall volume of agrochemicals applied has nearly doubled since the publication of Silent Spring. The last 40 years have brought significant changes with respect to environmental policies, agricultural technologies, urbanization, civil rights, women's rights, the roles of non-profit organizations and community development, and increased poverty, hunger, and economic inequality. In recent years, new voices, new analyses, and new movements have emerged offering fresh perspectives on how we can answer Carson's clarion call to protect our planet and ourselves. "
