Our forests are important sources of natural wealth, covering one-fifth of country's land
area. They supply the timber for the railways, buildings and furniture making. They also
supply the fuel for cooking and the bamboo for paper-making. Medicinal herbs also come
from the forests.
In the olden days, our wisemen and philosophers had their ashrams in the forests.
These ashrams were centres of knowledge and learning. Those sages had done an excellent
job of maintaining our forests. So we had wonderful forests.
Unfortunately, forests were ruthlessly cut down in the past few years. While the forests
are disappearing, the demand for timber is growing. We must, therefore, protect and develop
our forests. Vanamahotsav is an important step in this direction. It is observed for a week in
July every year. During this week, lakhs of saplings are planted throughout the country. This
is being done to restore our fast disappearing forests.
Still, deforestation poses a serious threat to forests on the earth. Deforestation causes
soil erosion, sudden floods and global warming.
