global increases in greenhouse gas emissions
and their effect on rising sea levels, which threaten the country's
underground water table

Uganda:
draining of wetlands for agricultural use; deforestation;
overgrazing; soil erosion; water hyacinth infestation in Lake
Victoria; poaching is widespread

Ukraine:
inadequate supplies of potable water; air and water
pollution; deforestation; radiation contamination in the northeast
from 1986 accident at Chornobyl' Nuclear Power Plant

United Arab Emirates:
lack of natural freshwater resources being
overcome by desalination plants; desertification; beach pollution
from oil spills

United Kingdom:
continues to reduce greenhouse gas emissions (has
meet Kyoto Protocol target of a 12.5% reduction from 1990 levels and
hopes to reduce even more); small particulate emissions, largely
from vehicular traffic, remain a problem; solid waste continues to
rise and recycling is very limited

United States:
air pollution resulting in acid rain in both the US
and Canada; the US is the largest single emitter of carbon dioxide
from the burning of fossil fuels; water pollution from runoff of
pesticides and fertilizers; very limited natural fresh water
resources in much of the western part of the country require careful
management; desertification

Uruguay:
water pollution from meat packing/tannery industry;
inadequate solid/hazardous waste disposal

Uzbekistan:
drying up of the Aral Sea is resulting in growing
concentrations of chemical pesticides and natural salts; these
substances are then blown from the increasingly exposed lake bed and
contribute to desertification; water pollution from industrial
wastes and the heavy use of fertilizers and pesticides is the cause
of many human health disorders; increasing soil salination; soil
contamination from agricultural chemicals, including DDT

Vanuatu:
a majority of the population does not have access to a
potable and reliable supply of water; deforestation

Venezuela:
sewage pollution of Lago de Valencia; oil and urban
pollution of Lago de Maracaibo; deforestation; soil degradation;
urban and industrial pollution, especially along the Caribbean
coast; threat to the rainforest ecosystem from irresponsible mining
operations

Vietnam:
logging and slash-and-burn agricultural practices
contribute to deforestation and soil degradation; water pollution
