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

Armenia
soil pollution from toxic chemicals such as DDT; the energy
crisis of the 1990s led to deforestation when citizens scavenged for
firewood; pollution of Hrazdan (Razdan) and Aras Rivers; the
draining of Sevana Lich (Lake Sevan), a result of its use as a
source for hydropower, threatens drinking water supplies; restart of
Metsamor nuclear power plant in spite of its location in a
seismically active zone

Atlantic Ocean
endangered marine species include the manatee, seals,
sea lions, turtles, and whales; drift net fishing is hastening the
decline of fish stocks and contributing to international disputes;
municipal sludge pollution off eastern US, southern Brazil, and
eastern Argentina; oil pollution in Caribbean Sea, Gulf of Mexico,
Lake Maracaibo, Mediterranean Sea, and North Sea; industrial waste
and municipal sewage pollution in Baltic Sea, North Sea, and
Mediterranean Sea

Australia
soil erosion from overgrazing, industrial development,
urbanization, and poor farming practices; soil salinity rising due
to the use of poor quality water; desertification; clearing for
agricultural purposes threatens the natural habitat of many unique
animal and plant species; the Great Barrier Reef off the northeast
coast, the largest coral reef in the world, is threatened by
increased shipping and its popularity as a tourist site; limited
natural fresh water resources

Austria
some forest degradation caused by air and soil pollution;
soil pollution results from the use of agricultural chemicals; air
pollution results from emissions by coal- and oil-fired power
stations and industrial plants and from trucks transiting Austria
between northern and southern Europe

Azerbaijan
local scientists consider the Abseron Yasaqligi
