Declining forest cover in malaysia results primary from urbanization,agricultural fires and forest conversion for oil-palm plantations and other forms of agriculture.However,recent report showed that the population of Malaysia has increased to 27 million people and this can cause very serious problems to the biodiversity as there are more and more forests need to be cleared to built the housing estates.
One of the main effects of deforestation to biodiversity is erosion.The soil erosion is caused when the forests have been cut down,essential nutrients are washed out of the soil all-together.When there are no trees to keep the soil in place,the soil become ripe for erosion.It dries and cracks under the sun's heat.Furthermore,rainfall washes remaining nutrients into rivers.As the result,the soil might be completely stripped of essential nutrients and the land will be useless.
Flooding is a quite serious consequence of deforestation.Clearing the forest dramatically increases the surface run-off from rainfall,mainly because a greater proportion of the rain reaches the ground due to a lack of vegetation which would suck up the excess rainfall.In areas where there is little vegetation will cause the flood.
Deforestation will also destroy the habitat of the rainforest in Malaysia and lead to the problem of animal extinction.Animals are forced to move to another place to survive.They will fight among each other and of course,the weakest will be eliminated.It is quite often to see some rare animals running over the streets looking for food in Malaysia big cities nowadays.You can easily find a squirrel looking for food in the garbages.Many animals will extinct because of this bad conditions.
