Afforestation is very useful to prevent and maintain the oxygen levels. Due to the deforestation, many of the trees are being cut and the oxygen supply has been reduced very drastically. Afforestation will help to maintain the oxygen levels in the atmosphere and helps the individual and the world to be healthy all the time. Oxygen is the minimum need for the individual to survive on the earth. If there is no oxygen, then which will cannot live or survive. When there is no o2, It is equally difficult for the animals to survive.

It also helps to maintain good forests. Deforestation, that is cutting of the trees makes the land abandoned and trees life less. When an individual takes a step forward to plant trees that is afforestation, good number of trees will be grown and the forests will be developed.

The most important thing for the animal’s survival is trees that give shelter and plants for the food. When the trees are being cut, some of the animals find no shelter and sometimes no food to eat. When afforestation takes place animals will find good shelter and also good food to eat.

Importance of Afforestation :

Afforestation helps to addess all the issues of soil erosion and barren land at the same time. Tress acts as wind barriers thereby weakening the speed of the wind and reducing its impact and ability to carry big soil particles.

The impacts of afforestation is occuring in many parts of world, can modify the nature and transformations of soil organic carbon and associated soil prevents, which in turn can affect plant diversity and ecosystem function. Afforestation also decreased soil bulk density and pH, and increased soil water content.

Types of Afforestation :

Afforestation materials are mainly divided into three categories: seed,seedling,and cutting. The choice of these three types of afforestation materials and methods is related to site conditions, tree species and age.

Various causes of Afforestation :

* Afforestation is highly fundamental in creating an alternative source pool of nature resource.

* Afforestation aids in tackling global warming and stabilizing global temperatures.

* protection of sensitive areas, biodiversity, and natural cycles.

* Afforestation can support wildlif.

* Afforestation creates employment and can provide a source of livelihood.

Advantages of Afforestation :

* A constant supply of forest products.

* prevents soil erosion.

* stabilizes the climate.

* Has the potential of reversing global warming and climate change.

* Better quality air.

* Improve watershed.

* preservation of wildlife.

* provision of employment and economic opportunities.

Disadvantages of Afforestation :

If not properly managed, afforestation can result in a reduction of local biodiversity, the modification of particular biomes, the intriduction of non – native and potentially invasive species, reduced stream flow and lost revenue from agricultural.
