| 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 |
