Question

Q.6 It takes 17 full grown trees to make one tonne of paper. Therefore, we should save
paper. Paper can be recycled five to seven times for use. If each student saves at least one
sheet of paper in a day, we can save many trees in a year. We should save, reuse used paper
and recycle it. By this we not only save trees but also save energy and water needed for
manufacturing paper. Moreover, the amount of harmful Chemicals used in paper making
will also be reduced. The answer to deforestation is reforestation.
Reforestation is restocking of the destroyed forests by planting new trees.
The planted trees should generally be of the same species which were found in that forest.
We should plant at least as many trees as we cut. Reforestation can take place naturally
also. If the deforested area is left undisturbed, it re-establishes itsell. In natural
reforestation there is no role of human beings. We have already made a tremendous
damage to our forests. If we have to retain our green wealth for generations, plantation of
more trees is the only option
