Question

problem solving -some students from your school throw their books and note books after thier exams......what would be the reason of throwing the books??what can be done to stop this?

Answer 1

The reason must be that those books had troubled them a lot that year and now they can't trouble them more.
We can launch programs in school to donate the books to poors after exams

Answer 2

Reason is that the students are done with that year.  They are happy.  Also they do not care anymore for them, as they are not of any use to them.  Some students do not want to give books to others, as they do not want their things being shared or used by others.

To stop this, schools can encourage book collection after exams.  They could arrange book buyers to come near schools and take all books for money or other favours...

Also, voluntary organizations can be invited to schools for collecting books after exams or during the exams.

    community centers can collect books and distribute among students in that area.   this is an excellent choice and plan.

   Paper recycling is very good.  Perhaps some city level or town level collection of old and crumpled books and rough notes  could be done.  That will serve as raw material for fresh new paper production.
 
   All of us either rich or poor, should realize that paper, books are valuable.  If we have no use for them, let someone else who is desperate for them have them.  Show good will and be Kind and considerate.
