Deforestation is the clearance of naturally occuring forestsby
cutting or burning.
It is the conversion of forested areas into non forested
land.
For use.
The process of deforestation often takes place in

The removal or destruction of significant areas of forestcover
has resulted in a degraded environment with
reducedbio-diversity.

Commercial logging companies cut down maturetrees that have been
selected for their timber.
Timber trade defends itself by saying that thismethod of

Undistributed and logged forest areas are being totallycleared
to provide land for food crops, tree plantations and

The major cause of deforestation is population growth
aspopulation growth results in increase in demand of woodproducts
or forested land.
To meet the increasing demand for wood and pulp forhouses,
furniture and paper developed countries haveturned to the huge
reserves of tropical forests.
For the rapidly growing population of AFRICA and ASIA,wood
remains the primary source of fuel for cooking andheating.

Mining and industrial development leads to directforest loss due
to the clearing of land to establishprojects.
Indigenous people are displaced.
Roads are constructed through previouslyinaccessible lands,
opening up the forests.
Severe water, air and land pollution occurs frommining and
industrial development.
