In the 21st century, “show-me-the-bodies” seems a cruel and outdated foundation for public policy. Yet history is littered with examples—like tobacco and asbestos—where only after the death toll mounts is the price of inaction finally understood to exceed that of action. In 19th century England, women factory inspectorate workers’ warnings about crippling lung disease in teenagers working with asbestos were ignored until evidence of the epidemic toll of factory work became overwhelming more than a half century later. Modern parallels are very much with us. Lung cancer in a young Chinese girl who grew up in a polluted urban environment and breast cancer in a 21-year-old young woman who kept her cell phone in her bras are stunning indications of modern hazards where we cannot afford to wait for broader public impacts before reining in exposures.
