Panoramic in scope, Plagues upon the Earth traces the role of disease in the transition to farming, the spread of cities, the advance of transportation, and the stupendous increase in human population. Harper offers a new interpretation of humanitys path to control over infectious diseaseone where rising evolutionary threats constantly push back against human progress, and where the devastating effects of modernization contribute to the great divergence between societies. The book reminds us that human health is globally interdependentand inseparable from the well-being of the planet itself."--]cFrom publisher's description.
