As we know paper is made from pulp of trees and for that millions of trees are being cut every year.As per information pulp for producing 1 ton of paper, approximately 12 trees are required .This year NCERT has ordered for printing 3200000 books to provide in CBSE schools. If we assume minimum weight of one book is 1kg then for producing 3200 ton paper 43200 trees has been cut down.If in one hectare land there are 500 trees then approximately 86400 hectare land had been deforested. That in resulted huge deforestation. Similarly printing ink pollutes our water resources because ink producing companies uses chemicals and releasees dirty and polluted water in rivers.
But if we start encourageing reuse of books then we can save for our environment as well as we can develop giving sence to society in our students.
