Groundwater contamination has led to inadequate supplies of drinking water in many areas of Vietnam. Only 98 percent (2006) of the urban population has access to safe drinking water. Chemicals sprayed during the Vietnam War caused widespread defoliation in the country’s forests, contributing to soil degradation and water pollution. Coastal water pollution, along with severe overfishing, has greatly endangered the country’s marine life.
Deforestation rates in Vietnam were high in the late 20th century as a result of logging, agriculture, and heavy bombing during times of war. Forests cover 39 percent (2005) of Vietnam, and only 3.9 percent (2007) of the land is protected in parks and other reserves. Vietnam is party to international treaties concerning climate change, endangered species, hazardous wastes, ship pollution, and wetlands. "Vietnam" © Emmanuel BUCHOT, Encarta, Wikipedia
