| Country | Environment - current issues |
| 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 |
| 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 populations; inadequate supplies of potable water; development of the Tigris and Euphrates rivers system contingent upon agreements with upstream riparian Turkey; air and water pollution; soil degradation (salination) and erosion; desertification |
| Ireland | water pollution, especially of lakes, from agricultural runoff |
| Isle of Man | waste disposal (both household and industrial); transboundary air pollution |
| Israel | limited arable land and natural fresh water resources pose serious constraints; desertification; air pollution from industrial and vehicle emissions; groundwater pollution from industrial and domestic waste, chemical fertilizers, and pesticides |
| Italy | air pollution from industrial emissions such as sulfur dioxide; coastal and inland rivers polluted from industrial and agricultural effluents; acid rain damaging lakes; inadequate industrial waste treatment and disposal facilities |
| Jamaica | heavy rates of deforestation; coastal waters polluted by industrial waste, sewage, and oil spills; damage to coral reefs; air pollution in Kingston results from vehicle emissions |
| Jan Mayen | NA |
| Japan | air pollution from power plant emissions results in acid rain; acidification of lakes and reservoirs degrading water quality and threatening aquatic life; Japan is one of the largest consumers of fish and tropical timber, contributing to the depletion of these resources in Asia and elsewhere |
| Jersey | NA |
| Jordan | limited natural fresh water resources; deforestation; overgrazing; soil erosion; desertification |
| Kazakhstan | radioactive or toxic chemical sites associated with former defense industries and test ranges scattered throughout the country pose health risks for humans and animals; industrial pollution is severe in some cities; because the two main rivers that flowed into the Aral Sea have been diverted for irrigation, it is drying up and leaving behind a harmful layer of chemical pesticides and natural salts; these substances are then picked up by the wind and blown into noxious dust storms; pollution in the Caspian Sea; soil pollution from overuse of agricultural chemicals and salination from poor infrastructure and wasteful irrigation practices |
| Kenya | water pollution from urban and industrial wastes; degradation of water quality from increased use of pesticides and fertilizers; water hyacinth infestation in Lake Victoria; deforestation; soil erosion; desertification; poaching |
| Kiribati | heavy pollution in lagoon of south Tarawa atoll due to heavy migration mixed with traditional practices such as lagoon latrines and open-pit dumping; ground water at risk |
| Korea, North | water pollution; inadequate supplies of potable water; waterborne disease; deforestation; soil erosion and degradation |
| Korea, South | air pollution in large cities; acid rain; water pollution from the discharge of sewage and industrial effluents; drift net fishing |
| Kosovo | void |
