Albania
deforestation; soil erosion; water pollution from industrial
and domestic effluents
Algeria
soil erosion from overgrazing and other poor farming
practices; desertification; dumping of raw sewage, petroleum
refining wastes, and other industrial effluents is leading to the
pollution of rivers and coastal waters; Mediterranean Sea, in
particular, becoming polluted from oil wastes, soil erosion, and
fertilizer runoff; inadequate supplies of potable water
American Samoa
limited natural fresh water resources; the water
division of the government has spent substantial funds in the past
few years to improve water catchments and pipelines
Andorra
deforestation; overgrazing of mountain meadows contributes
to soil erosion; air pollution; wastewater treatment and solid waste
disposal
Angola
overuse of pastures and subsequent soil erosion attributable
to population pressures; desertification; deforestation of tropical
rain forest, in response to both international demand for tropical
timber and to domestic use as fuel, resulting in loss of
biodiversity; soil erosion contributing to water pollution and
siltation of rivers and dams; inadequate supplies of potable water
Anguilla
supplies of potable water sometimes cannot meet increasing
demand largely because of poor distribution system
Antarctica
in 1998, NASA satellite data showed that the Antarctic
ozone hole was the largest on record, covering 27 million square
kilometers; researchers in 1997 found that increased ultraviolet
light passing through the hole damages the DNA of icefish, an
Antarctic fish lacking hemoglobin; ozone depletion earlier was shown
to harm one-celled Antarctic marine plants; in 2002, significant
areas of ice shelves disintegrated in response to regional warming
Antigua and Barbuda
water management - a major concern because of
limited natural fresh water resources - is further hampered by the
clearing of trees to increase crop production, causing rainfall to
run off quickly
Arctic Ocean
endangered marine species include walruses and whales;
fragile ecosystem slow to change and slow to recover from
disruptions or damage; thinning polar icepack
Argentina
environmental problems (urban and rural) typical of an
industrializing economy such as deforestation, soil degradation,
desertification, air pollution, and water pollution
note: Argentina is a world leader in setting voluntary greenhouse
gas targets
