Agent Orange was actually a clear liquid defoliant used by the United States in the Vietnam War and was called "Agent Orange" because when shipped, the US contained it in

orange-striped containers to distinguish it from other herbicides used by the US in Southeast Asia.

During the Vietnam War, the official military purpose of Agent Orange was to destroy forests so that the Viet Cong guerrilla forces would have no place to hide.

In just 10 years, the US military sprayed more than 100 million liters of chemical defoliants over central Vietnam, the Central Highlands, and southern Vietnam. Provinces and cities from Quang Tri to Ca Mau were affected by Agent Orange/dioxin to varying degrees, the most severely affected areas being the Southeast region, Quang Tri, along the

Vietnam-Laos border, and Năm Căn (Cà Mau), causing the destruction of over 3 million hectares of forest, changing the forest ecosystem, 4.8 million people were exposed and genetically inherited for 2 to 3 generations later.
