Write any two causes and three effects of deforestation.
Answers
The clearing of forests (cutting of trees) and using the cleared land for other processes is called deforestation.
Various purposes for which trees are cut are as follows:
1. Building houses for the increasing population,
2. Developing Industries.
3. Creating land for cultivation.
4. Using wood as fuel and for making furniture.
Some natural causes for deforestation
1. forest fires, and
2. severe droughts.
Consequences of deforestation
1. It disturbs the natural living places of many plants and animals.
2. Pollution level increases. Level of carbon dioxide in the atmosphere would go up as fewer trees would mean that less CO2 would be used in photosynthesis. This would lead to global warming.
3. Increased temperature on earth would disturb the water cycle and may reduce rainfall. Droughts may Occur.
4. Groundwater level would go down.
5. It would lead to soil erosion and floods. Gradually the fertile land would get converted into desserts. This is called desertification.
6. Loss of fertility of soil will take place.
7. It would lead to a decrease in the water holding capacity of the soil. In the absence of trees and the root systems, water is not able to move down into the soil. So water flows over the soil and brings about floods.
8. A number of useful products obtained from trees are also lost when the trees are cut.
