Human activities have had tremendous impact on forests. Since agriculture began 11,000 years ago,
large forest areas have been cleared for farms and cities. Beginning in the 1800’s, great expanses of forest
have also been eliminated because of industrial needs. The destruction and degrading of forests is called
deforestation.
Severe deforestation now occurs around the world, even in the most remote rain forests. Until the late
1940’s, rain forests covered about 8, 7 million square miles (22, 5 million square kilometres) of the earth’s
land. Today, they cover less than half that area. Millions of acres or hectares of rain forests are destroyed each
year. Since1800, huge areas of temperate forests have also been cleared. Many parts of eastern North
America, for example, have less than two percent of even degraded forests remaining.
Industrial pollution is a chief cause of deforestation. Factories often release poisonous gases into the air
and dangerous wastes into the lakes and rivers. Air pollution may combine with rain or other precipitations
and fall to earth as acid rain. The latter and polluted water can restrict plant growth or even kill most plants
in a forest.
