Andrew woke up with a guinea worm coming out of his foot as a result of drinking unsafe water a year previously. Anjali awoke with a cough because smoke from kilns filled her dilapidated home.

The stories, most set in poor communities, draw attention to the effects of air, water, food, climate, urbanization, and other human impacts on health. A comprehensive teaching guide provides a context from which readers can explore problems and solutions in environmental health.
