Hypothesis, findings and conclusion on results of deforestation, soil erosion and water pollution

Deforestation is said to be the cause of soil erosion. Deforestation generally increases rates of soil erosion, by increasing the amount of runoff and reducing the protection of the soil from tree litter.

When forest areas are cleared, it results in exposing the soil to the sun, making it very dry and eventually, infertile, due to volatile nutrients such as nitrogen being lost. In addition, when there is rainfall, it washes away the rest of the nutrients, which flow with the rainwater into waterways.

With deforestation, this hydraulic regulation is destroyed and reduces the absorption capacity. Therefore, rain floods the ground and streams down to a nearby river. While streaming down, it brings a huge amount of mud, filling up the river, which results in water pollution.

Soil erosion, which is caused by deforestation, not only caused water pollution, but also serious problems to the farmers. Deforestation causes soil to be totally devoid of essential nutrients and as a result cultivation in this land will also become impossible, resulting in the land becoming useless. Large tracts of land will also be rendered permanently impoverished due to soil erosion. Farmers will thus have serious problems when it comes to farming.

In conclusion, deforestation, soil erosion and water pollution are all interconnected. Deforestation leads to soil erosion which causes a large amount of soil being washed downstream and pollute the water courses. In addition, it also causes infertile land which is a disaster to farmers.
