Deforestation, which is the loss of wild forest habitats due to human activity, has grown into a global problem as demand for wood climbs. Shrinking forests can cause wide-reaching problems, including soil erosion, water cycle disruption, greenhouse gas emissions and biodiversity losses. Combined, these four issues affect not only wild plants and animals but human beings as well.
Deforestation and forest degradation can happen quickly, such as when a forest is clear-cut to make way for a palm oil plantation or a new settlement. It can also happen gradually as a result of ongoing forest degradation as temperatures rise due to climate change caused by human activity. The most common pressures causing deforestation and severe forest degradation are agriculture.
The local level is where deforestation has the most immediate effect. With forest loss, the local community loses the system that performed valuable but often under-appreciated services like ensuring the regular flow of clean water and protecting the community from flood and drought. The forest acts as a sort of sponge, soaking up rainfall brought by tropical storms while anchoring soils and.
Nevertheless, deforestation is a very big and important environmental problem which is yet to be effectively addressed. According to Norman Myers, who published a book on the subject in 1979, the main causes of deforestation are excessive logging, slash and burn agriculture, cattle raising and harvesting for fuel.
Deforestation and over-grazing have been causing tremendous land erosion and landslides. On an average India is losing about 6,000 million ton of top soil annually due to water erosion in the absence of trees. The loss worked out from the top soil erosion in 1973 was Rs. 700 crore, in 1976, 1977 and in 1978 was Rs. 889 crore, Rs. 1,200 crore and Rs. 1,091 crore respectively.
Why Does Deforestation Happen? The Answer Will Break Your Heart. Deforestation is happening worldwide at an alarming rate and the rapid loss of green cover is a major matter of concern. Subsistence farming is responsible for 48% of deforestation.
Malaysia had the world’s highest rate of forest loss between 2000 and 2012, according to a new global forest map developed in partnership with Google. Malaysia’s total forest loss during the.
Deforestation affects the people and animals where trees are cut, as well as the wider world. Some 250 million people living in forest and savannah areas depend on them for subsistence and income.
