Deforestation In Rainforests
Rainforests are also called the “carbon sink” of the Earth because they absorb vast amounts of carbon dioxide during photosynthesis and at the same time release oxygen into the atmosphere.
5. They also serve as water catchment areas.
Causes of Deforestation
Deforestation affects carbon and nitrogen cycles. The removal of plants in the rainforests disrupts the natural cycle of nutrients. The level of atmospheric carbon dioxide rises as less carbon dioxide is removed from the air by plants during photosynthesis. The recycling of nitrates and other ions is slowed down. Tree roots bind soil particles together, and the tree canopy reduces the force of rain beating down on the soil. Deforestation therefore causes nutrients to be lost through leaching and fun-off.
Deforestation causes climate changes. Deforestation disrupts normal weather patterns, creating hotter and drier weather and causing global climatic changes. On a global scale, the removal of trees reduces transpiration, rainfall and the rate at which plants use carbon dioxide in the atmosphere during photosynthesis. This leads to an increase in the carbon dioxide level in the atmosphere. Rising levels of carbon dioxide prevent heat from escaping from the atmosphere. This is known as the greenhouse effect and it is believed to lead to global …show more content…
During the rain seasons and it rains for a long period of time, the top layer of soil loosens and slide down which cause landslides. Landslides may cause the loss of lives and properties. Deforestation causes the soil to lose its stability. Decreasing of trees causes there is lack of tree leaves to protect the soil from the collision of raindrops and also causes the lack of tree roots to hold the soil. Thus, the soil is exposed directly to the raindrop. The top layer of soil is easily washed away by the heavy rainfall. This leads to soil erosion. The water carries away the eroded soil and the eroded soil may be deposited in rivers. Rainwater flows quickly into rivers during heavy rain because there is no reservation of water by plant roots as well as water catchment areas. Due to oozing in the rivers, the water flow is slowed down and become blocked. Thus, water flow interior and causes flash floods in low areas. Flash floods may cause loss of lives and properties. Soil erosion will leads to loss of minerals for the land. The land cannot be used for
