water 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
very 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

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
compensated by desalination plants; desertification; beach pollution
from oil spills

United Kingdom
continues to reduce greenhouse gas emissions (has met
Kyoto Protocol target of a 12.5% reduction from 1990 levels and
intends to meet the legally binding target and move towards a
domestic goal of a 20% cut in emissions by 2010); by 2005 the
government aims to reduce the amount of industrial and commercial
waste disposed of in landfill sites to 85% of 1998 levels and to
recycle or compost at least 25% of household waste, increasing to
33% by 2015; between 1998-99 and 1999-2000, household recycling
increased from 8.8% to 10.3%

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; 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
shrinkage 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 b
