A Chinese proverb says “Planting a tree is better than having nine sons’. It means that a tree can provide better service to man than nine sons can provide. Indeed it is impossible for human beings to survive in this planet without the help of trees. Firstly, trees supply us with oxygen. Secondly, for a pollution-free atmosphere we need enough trees all around us. Felling trees has a relationship with the recurrence of natural calamities.
Trees prevent soil-erosion and protect against draught and arrest the encroachment of desert. Thorough and proper preservation of rain forests can be an answer to the menace of flood. The West Bengal Government Forestry Department distributes saplings free of cost every monsoon to increase the number of trees.
