Effects of Deforestation


The subject of deforestation and the effects that it has on the
environment have been heavily debated for a long time; particularly over the
last few years. Governments and large lumber companies see large profits in the
mass deforestation of forests and state that their actions are having few, if
any, harmful effects on the environment. Most people disagree with this and
think that the environmental effects are devastating and will become
irreversibly disastrous in the very near future. Whether or not the pros
outweigh the cons will be hotly debated for years to come but the fact is that
deforestation is harmful to the environment and leads to declining wildlife
populations, drastic changes in climate and loss of soil.
The loss of forests means the loss of habitats for many species. Current
statistics show that as many as 100 species become extinct every day with a
large portion being attributed to deforestation (Delfgaauw, 1996). "Edge
effects" are the destruction or degradation of natural habitat that occur on the
fringes of fragmented forests. The effects for the animals include greater
exposure to the elements (wind, rain etc…), other non-forest animals and humans
(Dunbar, 1993). This unnatural extinction of species endangers the world's food
supply, threatens many human resources and has profound implications for
biological diversity.
Another negative environmental impact of deforestation is that it causes
climate changes all over the world. As we learned in elementary school, plant
life is essential to life on earth as it produces much of the oxygen that is
required for humans and other organisms to breathe. The massive destruction of
trees negatively effects the quantity and quality of the air we breathe which
has direct repercussions on the quantity and quality of life among both humans
and animals alike. With this reduced amount of vital plant life comes the
increase of carbon dioxide levels in the earth's atmosphere. With these
increased levels of CO-2 come unnatural changes in weather patterns both locally
and globally. "The removal of forests would cause rainfall to decline more than
26%. The average temperature of soil will rise and a decline of 30% in the
amount of moisture will evaporate into the atmosphere" (Delfgaauw, 1996). This
leads to the global warming phenomenon which is also directly related to the
declining amounts of forest areas on the earth.
Soil erosion caused by deforestation is also a major concern among even
the most amateur environmentalists:

"When rain falls, some may sink to the ground, some may run off the
surface of the land, and flowing down towards the rivers and some may evaporate.
Running water is a major cause of soil erosion, and as the forests are cut down,
it increases erosion" (Delfgaauw, 1996).
