Presence  of  unwanted  substances  or  things  in  an

            environment is called pollution. We should not throw
            garbage,  plastics  and  waste  in  drains,  sewers  and

            rivers.



                                                            Recycle


            Waste is the garbage that is collected as result of leftover after your usage.

            Most of things are bio-degradable, i.e. they rot and break up and become part of

            the  Earth.  But  some  things  like  plastics  do  not  break  up.  Plastics  harm  our

            environment. They are not bio-degradable. Vegetables and fruits, waste paper
            and clothes do not harm the environment. They can be recycled. Instead of

            throwing away, we can recycle it. It means using again and again.


            Recycling conserves our natural resources and also saves environment.
