Serbia and Montenegro
pollution of coastal waters from sewage
outlets, especially in tourist-related areas such as Kotor; air
pollution around Belgrade and other industrial cities; water
pollution from industrial wastes dumped into the Sava which flows
into the Danube

Seychelles
water supply depends on catchments to collect rainwater

Sierra Leone
rapid population growth pressuring the environment;
overharvesting of timber, expansion of cattle grazing, and
slash-and-burn agriculture have resulted in deforestation and soil
exhaustion; civil war depleting natural resources; overfishing

Singapore
industrial pollution; limited natural fresh water
resources; limited land availability presents waste disposal
problems; seasonal smoke/haze resulting from forest fires in
Indonesia

Slovakia
air pollution from metallurgical plants presents human
health risks; acid rain damaging forests

Slovenia
Sava River polluted with domestic and industrial waste;
pollution of coastal waters with heavy metals and toxic chemicals;
forest damage near Koper from air pollution (originating at
metallurgical and chemical plants) and resulting acid rain

Solomon Islands
deforestation; soil erosion; many of the surrounding
coral reefs are dead or dying

Somalia
famine; use of contaminated water contributes to human
health problems; deforestation; overgrazing; soil erosion;
desertification

South Africa
lack of important arterial rivers or lakes requires
extensive water conservation and control measures; growth in water
usage outpacing supply; pollution of rivers from agricultural runoff
and urban discharge; air pollution resulting in acid rain; soil
erosion; desertification

South Georgia and the South Sandwich Islands
NA

Southern Ocean
increased solar ultraviolet radiation resulting from
the Antarctic ozone hole in recent years, reducing marine primary
productivity (phytoplankton) by as much as 15% and damaging the DNA
of some fish; illegal, unreported, and unregulated fishing in recent
years, especially the landing of an estimated five to six times more
Patagonian toothfish than the regulated fishery, which is likely to
affect the sustainability of the stock; large amount of incidental
mortality of seabirds resulting from long-line fishing for toothfish
note: the now-protected fur seal population is making a strong
comeback after severe overe
