Environmental disasters impact disadvantaged communities disproportionately both through the epidemiological challenge of exposure, but also by undermining the progress of public health efforts.

This article considers the implications of expanding hydroelectricity for war production and strategy using Canada, the United States and Germany during World War II as an example.
