ed and
contribute to desertification; water pollution from industrial
wastes and the heavy use of fertilizers and pesticides is the cause
of many human health disorders; increasing soil salination; soil
contamination from buried nuclear processing and agricultural
chemicals, including DDT

Vanuatu
a majority of the population does not have access to a
reliable supply of potable water; deforestation

Venezuela
sewage pollution of Lago de Valencia; oil and urban
pollution of Lago de Maracaibo; deforestation; soil degradation;
urban and industrial pollution, especially along the Caribbean
coast; threat to the rainforest ecosystem from irresponsible mining
operations

Vietnam
logging and slash-and-burn agricultural practices contribute
to deforestation and soil degradation; water pollution and
overfishing threaten marine life populations; groundwater
contamination limits potable water supply; growing urban
industrialization and population migration are rapidly degrading
environment in Hanoi and Ho Chi Minh City

Virgin Islands
lack of natural freshwater resources

Wake Island
NA

Wallis and Futuna
deforestation (only small portions of the original
forests remain) largely as a result of the continued use of wood as
the main fuel source; as a consequence of cutting down the forests,
the mountainous terrain of Futuna is particularly prone to erosion;
there are no permanent settlements on Alofi because of the lack of
natural fresh water resources

West Bank
adequacy of fresh water supply; sewage treatment

Western Sahara
sparse water and lack of arable land

World
large areas subject to overpopulation, industrial disasters,
pollution (air, water, acid rain, toxic substances), loss of
vegetation (overgrazing, deforestation, desertification), loss of
wildlife, soil degradation, soil depletion, erosion

Yemen
very limited natural fresh water resources; inadequate
supplies of potable water; overgrazing; soil erosion; desertification

Zambia
air pollution and resulting acid rain in the mineral
extraction and refining region; chemical runoff into watersheds;
poaching seriously threatens rhinoceros, elephant, antelope, and
large cat populations; deforestation; soil erosion; desertification;
lack of adequate water treatment presents human health risks

Zimbabwe
deforestation; soil erosion; land degradation; air and
water pollut
