All cannot be used in a long-term because

All over the world
today, it is noticeable by many that the problem of deforestation has drastically
arisen. Deforestation means the chopping down of trees in a large area, or the
demolition of forests by people for another purposes. Deforestation is because
of agricultural activities as well as economic and social growth and can give
catastrophic impacts to the soil and climate. So this essay is going to discuss
the factors and impacts of deforestation.

Firstly, the cause of deforestation is agriculture
especially in terms of slash and burn technique and cattle ranching. Some
people use slash and burn technique, in which they use fire to clear the forest
before converting it to agricultural land. The newly cleared land provides a
layer of ash, which is actually very rich in nutrient to help for the growth of
crops. However, these lands cannot be used in a long-term because the soil will
eventually wear out of nutrients. When the soil is infertile, the farmers will
burn another forest and grow their crops, and this process will always be
repeated. This method can lead to deforestation as many forests are being burnt
year by year for agriculture. In addition to that, cattle ranching are also
major cause of deforestation especially in Central and South America. In the
old days, cattle ranching were mostly done in dry forest and savannah that is
far away from the equator. However, ranchers nowadays will prefer moist
tropical rainforest. This activity actually covers large area of forests. The
cattlemen can buy and clear the land on their own or buy cleared lands for
their cattle to live in. The cycle will be repeated, as they will appoint the
cleared land to other farmers and clear more forests. According to McLeish
(2007), in Central America alone, the area of lands that have been converted
into pasture has increased from 3.9 million hectares to 13.4 million hectares.
