Honduras
urban population expanding; deforestation results from
logging and the clearing of land for agricultural purposes; further
land degradation and soil erosion hastened by uncontrolled
development and improper land use practices such as farming of
marginal lands; mining activities polluting Lago de Yojoa (the
country's largest source of fresh water), as well as several rivers
and streams, with heavy metals

Hong Kong
air and water pollution from rapid urbanization

Howland Island
no natural fresh water resources

Hungary
the upgrading of Hungary's standards in waste management,
energy efficiency, and air, soil, and water pollution to meet EU
requirements will require large investments

Iceland
water pollution from fertilizer runoff; inadequate
wastewater treatment

India
deforestation; soil erosion; overgrazing; desertification; air
pollution from industrial effluents and vehicle emissions; water
pollution from raw sewage and runoff of agricultural pesticides; tap
water is not potable throughout the country; huge and growing
population is overstraining natural resources

Indian Ocean
endangered marine species include the dugong, seals,
turtles, and whales; oil pollution in the Arabian Sea, Persian Gulf,
and Red Sea

Indonesia
deforestation; water pollution from industrial wastes,
sewage; air pollution in urban areas; smoke and haze from forest
fires

Iran
air pollution, especially in urban areas, from vehicle
emissions, refinery operations, and industrial effluents;
deforestation; overgrazing; desertification; oil pollution in the
Persian Gulf; wetland losses from drought; soil degradation
(salination); inadequate supplies of potable water; water pollution
from raw sewage and industrial waste; urbanization

Iraq
government water control projects have drained most of the
inhabited marsh areas east of An Nasiriyah by drying up or diverting
the feeder streams and rivers; a once sizable population of Marsh
Arabs, who inhabited these areas for thousands of years, has been
displaced; furthermore, the destruction of the natural habitat poses
serious threats to the area's wildlife popul
