supplies must be met by rainwater catchments

Central African Republic
tap water is not potable; poaching has
diminished the country's reputation as one of the last great
wildlife refuges; desertification; deforestation

Chad
inadequate supplies of potable water; improper waste disposal
in rural areas contributes to soil and water pollution;
desertification

Chile
widespread deforestation and mining threaten natural
resources; air pollution from industrial and vehicle emissions;
water pollution from raw sewage

China
air pollution (greenhouse gases, sulfur dioxide particulates)
from reliance on coal produces acid rain; water shortages,
particularly in the north; water pollution from untreated wastes;
deforestation; estimated loss of one-fifth of agricultural land
since 1949 to soil erosion and economic development;
desertification; trade in endangered species

Christmas Island

Cocos (Keeling) Islands
fresh water resources are limited to
rainwater accumulations in natural underground reservoirs

Colombia
deforestation; soil and water quality damage from overuse
of pesticides; air pollution, especially in Bogota, from vehicle
emissions

Comoros
soil degradation and erosion results from crop cultivation
on slopes without proper terracing; deforestation

Congo, Democratic Republic of the
poaching threatens wildlife
populations; water pollution; deforestation; refugees responsible
for significant deforestation, soil erosion, and wildlife poaching;
mining of minerals (coltan - a mineral used in creating capacitors,
diamonds, and gold) causing environmental damage

Congo, Republic of the
air pollution from vehicle emissions; water
pollution from the dumping of raw sewage; tap water is not potable;
deforestation

Cook Islands
NA

Coral Sea Islands
no permanent fresh water resources

Costa Rica
deforestation and land use change, largely a result of
the clearing of land for cattle ranching and agriculture; soil
erosion; coastal marine pollution; fisheries protection; solid waste
management; air pollution

Cote d'Ivoire
deforestation (most of the country's forests - once
the largest in West Africa - have been heavily logged); water
pollution from sewage and industrial and agricultural effluents

Croatia
air pollution (from metallurgical plants) and resulting acid
rain is damaging the
