Good Morning Students – Hope you are doing well!

Today, I am going to address a very pertinent topic linked with global warming, i.e. Deforestation. Deforestation is a grim reality of the present times. It is an act of cutting down trees and clearing away forest lands and not replanting them elsewhere. The process of deforestation usually takes place when a piece of land is converted into ranches, farms or big construction houses. Other than this, deforestation also occurs because of the need for fuel or wood which leads to the destruction of trees. When deforestation happens, not only trees are destroyed, but animals are also rendered homeless as their natural habitat, i.e. forest is destroyed by man. It also affects our climate and lead to global warming.

There are many reasons behind deforestation, let’s know some of them:

Deforestation, as mentioned above, is the act of cutting down trees. When population grows, people start clearing away forest land to build their homes and factories. Besides, land is also used for farming purposes. The wood in turn is used as lumber in the construction of buildings and apartments and the trees are burned as firewood. Forests are also destroyed in order to make cities grow bigger and impressive, which means the construction of pavement and roads. Other reasons are:

Forest Fire

Huge fire takes place in forests which result in their massive destruction.

Answer:

1. Introduction...

2. The denudation of forests:

Out failure to take care of our forests is threatening the very existence of man and wildlife. Legal and illegal commercial logging had taken its toll on our environment. Commercial logging is not to be taken lightly. The industry is buzzing with bribery and kickbacks. It is not a secret that through corruption a person can obtain concession for felling trees and transport clearance. Logging forests is a brutal business. In felling a large mature tree hundreds of smaller trees and saplings are destroyed.

3. Trees stabilize the soil. In the absence of trees and forests the fertile top soil is washed away by rainwater making cultivation impossible.

3. Trees prevent desertification. The famous Pink City, Jaipur is being encroached by desert due to the absence of trees. Greenery is not mere foliage. Eucalyptus and teak are incapable of imparting much stability to the soil structure.

4. Trees retain water in the soil. Without forests the entire rainwater flows into the sea. The water is then not available as ground water. Thus we experience flash floods followed by severe droughts. The underground water level also sinks and cultivation becomes impossible. Cherrapunji is synonymous with heavy rain. But due to the absence of trees to prevent soil erosion and retain ground water acute water scarcity prevails in winter.

5. If deforestation continues unchecked and if afforestation is not taken up on a war footing, water management experts warned that there will be violent riots for water due to scarcity caused by droughts and pollution of rivers and lakes.

6. Trees are water bearer. Without trees rainfall will decrease and cultivation will become rather a matter of luck. Worldwide food scarcity causing famines is expected as food grain productions diminished due to low and unpredictable rainfall.

7. Trees are oxygen cylinders. Trees absorb the harmful Carbon dioxide and release Oxygen. Deforestation contributes to the decrease in oxygen level and increase Carbon dioxide in the atmosphere. Increased Carbon dioxide level results in lungs diseases, cancer and lower life expectancy.

8. Trees are air conditioners. Trees keep the temperature temperate. Trees and forests are habitats of wild birds and animals. They are store house of many medicinal plants.

9. Trees also reduce air and noise pollution and add beauty to the landscape.
