Examines how recent trends in globalization and the altering of ecosystems have led to dramatic increases in the spread of infectious diseases. Case studies demonstrate just how closely our own health is dependent on that of the environment.

  • Peru: As the forests are cleared and wildlife eradicated, vectors of disease must seek out new hosts on which to feed—namely humans.
  • Bangladesh: Lacking clean water and adequate sanitation, seasonal outbreaks of cholera make hospitals look like battlefields littered with casualties.
  • United States: In the Chesapeake Bay, waterman struggled to survive as their harvest of fish and crabs have become increasingly polluted by sewage, pesticides and industrial effluents.
