fishing

Canada:
air pollution and resulting acid rain severely affecting
lakes and damaging forests; metal smelting, coal-burning utilities,
and vehicle emissions impacting on agricultural and forest
productivity; ocean waters becoming contaminated due to
agricultural, industrial, mining, and forestry activities

Cape Verde:
overgrazing of livestock and improper land use such as
the cultivation of crops on steep slopes has led to soil erosion;
demand for wood used as fuel has resulted in deforestation;
desertification; environmental damage has threatened several species
of birds and reptiles; overfishing

Cayman Islands:
no natural fresh water resources; drinking water
supplies must be met by rainwater catchment

Central African Republic:
tap water is not potable; poaching has
diminished its 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:
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:
NA

Clipperton Island:
NA

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

Colombia:
deforestation; soil 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 who arrived in
mid-1994 were responsible for significant deforestation, soil
erosion, and wildlife poaching in the eastern part of the country
(most of those refugees were repatriated in November and December
1996)
