Restoring Vietnam's Forests

During the Vietnam War, vast amounts of defoliant were released by the US military in order to destroy the tropical forests that concealed guerilla fighters. The dioxins contained in the defoliant destroyed foliage and soil, creating toxic hotspots and areas where only grass can grow even today. In this episode, we follow the 40-year campaign of Dr. Quy to restore the Vietnamese rainforests to their former glory.
