Question

What are the advantages of Reforestation?
A) It helps to reduce the concentration of $C{O_2}$ in the environment.
B) It has the potential to preserve endangered species.
C) It can reverse the damage done by erosion.
D) All of the above

Answer 1

Hint: Reforestation is the result of deforestation, which is described as the complete removal of trees by the United Nations Food and Agriculture Organization. Deforestation is normally the result of planned and deliberate tree felling, with the cleared land being used for activities unrelated to the forest.

Complete answer:
Reforestation is the process of replanting trees in a field or on a ground surface. Reforestation is the process of replanting trees in an area that has lost its forest cover due to a variety of factors. Reforestation is a deliberate or intended effort to replace vegetation that has been lost due to human activities, natural disasters, or abrupt climate change. With rising environmental consciousness, a global campaign to restore abandoned forest hamlets has been launched.

Balance of oxygen and carbon dioxide: Via absorption during photosynthesis, reforestation activities facilitate the gradual removal of $C{O_2}$ from the atmosphere. As a result, its concentration in the atmosphere is reduced. Photosynthesis releases oxygen, which aids in the maintenance of the $C{O_2}/{O_2}$ balance. Carbon dioxide emissions are lower, which means less pollution and global warming.

Prevent Soil erosion : Erosion is another environmental threat exacerbated by deforestation. Soil erosion and water pollution are prevented or reduced by the trees. Tree roots function as natural nets, extending deep into the earth and holding the soil in place. As a result of the prevention of soil runoff, vital nutrients are preserved and the soil remains fertile. Falling leaves and dry branches provide fertiliser to the soil.

Preserving the species : As more species are pushed out of their natural habitats, the earth's biodiversity is dwindling. Reforestation is the only way to counteract these negative consequences.

Maintaining water cycle : Forests retain moisture from their leaves and roots, which helps to sustain the area's water cycle. They are a natural rainwater storage system that helps to reduce aridity in the atmosphere. Trees save freshwater lakes from drying out by preventing them from losing moisture.

Transpiration (Moisturisation) : Any of the water absorbed by the trees is released as water vapour through the leaves. This is the mechanism of transpiration, which aids in the restoration of atmospheric moisture and the regulation of local temperature.

Thus the correct answer is option ‘D’.

Note: Forests have long been a valuable economic resource. The paper factory is reliant on tree-sourced wood pulp. The main occupation of the people in the coniferous area had been lumbering.

There are few Cons in reforestation:
-Maintenance of forests is costly.
-Less space for infrastructure.
