In India, every year central/state governments are distributing numbers of books(study material) to needy students in various schools/colleges under social welfare schemes. To print these books, a numbers of tree cutting are required, which affects on environment of earth. To save Earth from environment disturbance, we must stop tree cutting for frequent printing. We can reduce tree cutting by such mannered practice of reusing of printed books by recollect the same books from students those who finished their study and redistribute the same books to students of next year. Thus we can serve to our earth by "Save Tree" by reusing books. I appeals to respective government to do the Noble cause by recollect the Books and redistribute the same Books to students of upcoming year.
