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
Jarvis Island:
no natural fresh water resources
Jersey:
NA
Johnston Atoll:
no natural fresh water resources
Jordan:
limited natural fresh water resources; deforestation;
overgrazing; soil erosion; desertification
Juan de Nova Island:

Kazakhstan:
radioactive or toxic chemical sites associated with its
former defense industries and test ranges are found throughout the
country and pose health risks for humans and animals; industrial
pollution is severe in some cities; because the two main rivers
which 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
