f overgrazing and the expansion of
agriculture into marginal lands; deforestation (little forested land
remains because of uncontrolled cutting of trees for fuel); habitat
loss threatens wildlife populations

Cambodia
illegal logging activities throughout the country and strip
mining for gems in the western region along the border with Thailand
have resulted in habitat loss and declining biodiversity (in
particular, destruction of mangrove swamps threatens natural
fisheries); soil erosion; in rural areas, most of the population
does not have access to potable water; declining fish stocks because
of illegal fishing and overfishing

Cameroon
waterborne diseases are prevalent; deforestation;
overgrazing; desertification; poaching; overfishing

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
soil erosion; deforestation due to demand for wood used
as fuel; desertification; environmental damage has threatened
several species of birds and reptiles; illegal beach sand
extraction; overfishing

Cayman Islands
no natural fresh water resources; drinking water
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
loss of rainforest; impact of phosphate mining

Clipperton Island

Cocos (Keeling) Islands
