widespread poaching

Saint Helena:
NA

Saint Kitts and Nevis:
NA

Saint Lucia:
deforestation; soil erosion, particularly in the
northern region

Saint Pierre and Miquelon:
NA

Saint Vincent and the Grenadines:
pollution of coastal waters and
shorelines from discharges by pleasure yachts and other effluents;
in some areas, pollution is severe enough to make swimming
prohibitive

Samoa:
soil erosion

San Marino:
NA

Sao Tome and Principe:
deforestation; soil erosion and exhaustion

Saudi Arabia:
desertification; depletion of underground water
resources; the lack of perennial rivers or permanent water bodies
has prompted the development of extensive seawater desalination
facilities; coastal pollution from oil spills

Senegal:
wildlife populations threatened by poaching; deforestation;
overgrazing; soil erosion; desertification; overfishing

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; much 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 threatens to outpace 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
