While government enforcement of laws and regulations to control the production of chloroflurocarbons in 1987 has been hailed as exemplifying the precautionary principle, for almost two decades US companies failed to take precautionary measures to prevent chemical emissions, despite the probable risk of stratospheric ozone loss. As a result, human harms in the form of skin cancer have reached epidemic proportions globally and in the United States where, today, one person dies every hour from skin cancer. This book reviews U.S. laws, regulations, and policies, as well as case law regarding similar toxic tort cases to consider whether companies can and should be held legally liable under tort common law theories and related tort justice theories for having contributed to increased risks of skin cancer.
