Agent Orange is a mixture of herbicides that U.S. military forces sprayed in Vietnam from 1962 to 1971 during the Vietnam War. It was also the cause for much destruction during the war.
Among the Vietnamese, exposure to Agent Orange is considered to be the cause of an abnormally high incidence of miscarriages, skin diseases, cancers, birth defects, and congenital malformations.
The U.S. government has documented higher cases of leukemia, Hodgkin’s lymphoma, and various kinds of cancer in exposed veterans. An epidemiological study done by the Centers for Disease Control and Prevention showed that there was an impact of birth defects of the children of veterans as a result of Agent Orange.
Agent Orange also caused enormous environmental damage in Vietnam. Over 3,100,000 hectares (31,000 km2 or 11,969 mi2) of forest were defoliated. Defoliants eroded tree cover and seedling forest stock, making reforestation difficult in numerous areas. Animal species diversity sharply reduced in contrast with unsprayed areas.
The museum in Ho Chi Minh City (War Museum) details a lot of the impact of Agent Orange. There are a lot of images which show the dramatic effects of the agent. Some of these are too gruesome to be displayed. I would recommend each person to visit this museum.
