Throwing eatables and food items in dustbin is really very bad activity...we should immediately stop this activity. its dangerous because of all these things there will be attack of mosquitoes and houseflies in the classroom. there will be a bad and stinky smell too which will be uncomfortable for the teachers and students.
It may be because of the unawareness and carelessness of the students. And we
should make the students understand to stop all these things.....
