"On the Brink" (Part 1 of 3) examines the link between environmental pressures and political instability in visits to South Africa, Bangladesh, Peru and Haiti, and the U.S.-Mexican border.

And in Haiti, deforestation provides "a case study of a country verging on a complete economic and environmental collapse." Matt Damon narrates.
