For the last 150 years, chemicals have been tested on animals for the alleged purpose of protecting the public from their dangerous effects. Lethal Laws reveals that using animals as human surrogates is not only unethical, it is bad science. Alix Fano provides a meticulous analysis of the technical and scientific problems that have plagued animal tests for decades, but which have not been forcefully challenged until now. She shows how animal testing has been used as an alibi to allow the continued use of thousands of toxic chemicals. In a field dominated by male voices, this is a pioneering work by a woman that effectively demonstrates the causal link between animal testing and environmental degradation, and the subsequent deterioration of human health.
