Now days one can see forests only in movies and you-tube videos.
Because there is wide spread deforestation in the name of development.
More and more forest land is converted into agriculture land by the governments.
Forests have many advantages to the life on earth and also we humans.
The importance of forests can be seen in the recent time when there is much change in temperatures all over the globe.
The seasonal and climatic fluctuations are also due to deforestation.
Forests means a ecosystem of plants and animals.
And it is said even man once upon a time lived in forests.
He then vacated it to make villages and towns.
Now the present scenario is there are more towns and cities than forests.
We have many benefits from forest and man needs to conserve forests for his future generations.
Importance of Forest are as below.
Bring Rainfall: Forests are responsible for rains on the land. Due to forests , the clouds get cooled and convert to rain water. So one can notice heavy rainfall in the areas of forests and around. Forests slower the monsoon currents (winds) and let the clouds move slower over land. They also provide suitable low temperature for the water-vapor in the clouds to convert into water droplets and cause rain. Hence there are no rains in the deserts.
Prevent Soil erosion: Soil erosion is a common natural activity happening due to winds and floods. Growing of forests help minimize this soil erosion in the nearby farms. The importance of soil is too much that we can afford to loose the fertile top layers. This soils is useful to grow crops and trees.
Reduce the effect of natural calamities: In case of natural disaster like tsunami, floods, hurricanes, cyclonic winds etc. Presence of abundant forests help us minimize the effects of there tsunamis, floods and cyclonic winds. Hence when there was tsunami is Indian ocean the areas with many tress at the seashore had less damage than areas without any tress.
Home for animals (Ecosystem): Forests are some of the safest and comfortable homes for animals and birds. Many animals, birds can dwell peacefully in forests as it is a natural home for them. They even find sufficient food for the day and together with their herds or groups. Forests are heaven for animals now a days.
Minimize the pollution: It reduces air, sound and even thermal pollution. Forest have many plants and tress. The air on the earth moves from one place to another. Similarly the gas and air pollution diffuses to all over the air and get less severe. Presence of forest nearby helps these pollutants to be absorbed from the air.
Economic importance: Forest have a great economic importance. Sometimes the economy of a region depends largely on forests. Forests provide many natural resources which are of great value for money. Fore example in the recent times, the red sandal wood from the forests of Andhra pradesh have been found to be of immense value and the authorities are planning to capitalize the sale of the wood to run the government welfare schemes for the people. Similarly in Africa and other areas, the forest reserves are found to be of immense wealth to the nation.
Some of the notable examples of reserves with economic importance are
Medicine: Many plant drugs are extracted from plants grown in forest like cinchona, cinnamon, eucalyptus etc.
Though smaller medicinal plants are grown by farming, drugs from large tress are available from forests alone. The medicines procured by this method are mostly, alkaloids, glycosides, tannins etc. Besides one can also get essential oils.
Wood for Furniture: Forests are the sole reserve for best woods needed for furniture. There are many kinds of woods for different purposes like insect repellent ones (neem), red sandal, teak etc. can be found in forests.
Honey: This is a sugary liquid produced by honey bees after consuming nectar from flowers. This is widely used in medicine, ice-creams, sweets and other confectionery. It is largely obtained by cultivation using honey bees in controlled boxes. But honey from wild forest has its own taste and strength than this farmer made one.
Insect Wax: This is produced by lac insect. They can found in forests and the lac isolated is used for cosmetics and also a dye.
Picnic spots/leisure: Now a day many forests are exploited as picnic spots. Though this may be disturbing to the native animals and people still government encourage it for tourism revenue. There are various picnic and holiday packages offered to spend time in midst of forests.
