Description: Over the past 50 years we have all been unwitting participants in a vast, uncontrolled,
worldwide chemistry experiment involving the oceans, air, soils, plants, animals, and human
beings. The Chemicals Revolution has indeed contributed greatly to human well-being.
Chemicals have raised farming yields by killing crop pests and have made possible an endless
array of useful products. But once released into the world, some chemicals cause toxic reactions,
persist in the environment for years, travel thousands of kilometres from where they
were used, and threaten long-term health and ecological consequences that were never anticipated
or intended.
