Paper is used in our day to day life. Thousands of trees are cut to fulfil the demand of paper. If the trees are being cut for paper, there may be one day we will be left with no trees. So paper should be saved and should be used intelligently. The ways by which we can save paper are:
• We should recycle the waste paper.
• We should not litter paper here and there.
• Paper should be sent through proper channel for recycling.
• We should not tear our old books and donate it to poor children so that they can reuse those books.
• We should encourage buying recycled paper products.
• We should avoid taking paper bags from the shops, instead we should carry jute bags.
Plants need carbon dioxide for photosynthesis. Fewer trees would mean that less carbon dioxide will be used up resulting in its increased amount in the atmosphere.

The ever increasing demand in factories and for shelter, trees are being continually cut. If we have to retain our green wealth for generations, plantation of more trees is the only option. Cutting of trees can only be justified when reforestation is done.
Reforestation is the restocking of destroyed forests by planting new trees. The trees planted should be of the same species that are generally found in the forests. We should plant as many trees as we cut. Reforestation can take place naturally also if the land is left undisturbed. The forests will establish itself over a period of time.
We have damaged our forests to such an extent that it is difficult to retain the green wealth for our future generations. So it is very important to plant more trees and to find out ways of recycling and restoring our natural wealth.
