Timor-Leste
widespread use of slash and burn agriculture has led to
deforestation and soil erosion
Togo
deforestation attributable to slash-and-burn agriculture and
the use of wood for fuel; water pollution presents health hazards
and hinders the fishing industry; air pollution increasing in urban
areas
Tokelau
limited natural resources and overcrowding are contributing
to emigration to New Zealand
Tonga
deforestation results as more and more land is being cleared
for agriculture and settlement; some damage to coral reefs from
starfish and indiscriminate coral and shell collectors; overhunting
threatens native sea turtle populations
Trinidad and Tobago
water pollution from agricultural chemicals,
industrial wastes, and raw sewage; oil pollution of beaches;
deforestation; soil erosion
Tunisia
toxic and hazardous waste disposal is ineffective and poses
health risks; water pollution from raw sewage; limited natural fresh
water resources; deforestation; overgrazing; soil erosion;
desertification
Turkey
water pollution from dumping of chemicals and detergents; air
pollution, particularly in urban areas; deforestation; concern for
oil spills from increasing Bosporus ship traffic
Turkmenistan
contamination of soil and groundwater with agricultural
chemicals, pesticides; salination, water logging of soil due to poor
irrigation methods; Caspian Sea pollution; diversion of a large
share of the flow of the Amu Darya into irrigation contributes to
that river's inability to replenish the Aral Sea; desertification
Turks and Caicos Islands
limited natural fresh water resources,
private cisterns collect rainwater
Tuvalu
since there are no streams or rivers and groundwater is not
potable, most water needs must be met by catchment systems with
storage facilities (the Japanese Government has built one
desalination plant and plans to build one other); beachhead erosion
because of the use of sand for building materials; excessive
clearance of forest undergrowth for use as fuel; damage to coral
reefs from the spread of the Crown of Thorns starfish; Tuvalu is
concerned about global increases in greenhouse gas emissions and
their effect on rising sea levels, which threaten the country's
underground water table; in 2000, the government appealed to
Australia and New Zealand to take in Tuvaluans if rising sea levels
should make evacuation necessary
