The
global population has more than tripled this century, and will continue to grow
for the next 50 years, particularly in developing countries. World population is
expected to reach ten billion by 2050. Because the number of people living on
the planet increases every year, the number of forest products needed also
increases, forcing temperate and tropical rainforests to be cut down.
Almost half of all tropical deforestation has occurred in South America.
The rainforests of the world are disappearing at a rate of 80 acres per minute,
day and night… …major climatic and other environmental changes will occur if
this continues. The destruction of the rainforests cause carbon dioxide to be
released, which in turn allows the greenhouse effect to occur. The greenhouse
effect raises the temperatures all around the world, and can cause ice caps to
melt. When ice caps melt, the sea level rises, causing major flooding around the
world.
Traditionally there were three major causes of destruction to the rainforest:
 |
farming |
 |
ranching |
 |
and
logging |
Farmers
in rainforest countries are often poor and can’t afford to buy land. Instead,
these farmers clear the rainforest
land to grow their crops. Tropical rainforest soil is so poor in nutrients,
farmers cannot reuse the same land year after year. In following years, farmers
just clear more land, destroying the forest piece by piece.
Ranching also causes destruction of the
rainforests. Ranchers clear large areas of rainforest to become pastures for
their cattle. This land does not cost them very much, so they can sell cattle at
low prices. Because it is very profitable, ranchers continue to clear rainforest
land so they can raise and sell more cattle. During the 1980s, about 16.9
million hectares of tropical rainforest was cut down and replaced with farms and
grazing land for cattle.
The third major traditional reason for destruction of the rainforests is
logging. Trees from the rainforest are used for building houses, making
furniture, and providing pulp for paper products, such as newspapers and
magazines. Rainforest that was chopped down can grow back over time, but they
will never have the same variety of plants and animals they had.
The Amazon rainforest still remains as
it was years ago, with less destruction occurring than in many other forests,
because it is very large and remote. But the Amazon may not remain so peaceful
for long. Transnational corporations are now targeting the Amazon and the other
Rainforests.
Corporations have convinced many rainforest countries that it would improve
their economies by allowing the companies to use the land, and now these
countries economies have become dependent on it. Oil companies often attempt to
trick and bribe the Indians into signing over to them the rights of the land.
But the people have begun to fight back.
The rainforests are disappearing rapidly, and mainly for correctable problems…
that should have been corrected years ago. Tropical rainforests once covered
more than 14 percent of the Earth’s land area… they now amount to less than
6 percent.
