Today, there are thousands of synthetic chemicals used to make our clothing, cosmetics, household products, electronic devices, even our children's toys. Many of these chemicals help us live longer and more comfortable lives, but some of these highly useful chemicals are also persistent, toxic, and dangerous to our health and the environment. For fifty years, the conventional approach to hazardous chemicals has focused on regulation, barriers, and protection. In Chemicals without Harm, Ken Geiser proposes a different strategy, based on developing and adopting safer alternatives to hazardous chemicals rather than focusing exclusively on controlling them.
