Asl topic - you noticed some littering in the school corridor during break time inspite of cleanliness drive ..discuss with your partner what should be done to stop students from littering some points and i need it

You could try to have a contest of who could pick up the most trash in a limited amount of time. You could also give the winners a cash prize, so that more people could clean the area faster.
Petition the Principal to put up names of people who have been littering and announce their names so that they will never do it again

Hope this Helped :)

1.If you see someone littering, you can either tell them to stop, but if you're shy or feel rude then you can go pick it up
2.maybe twice a month or once a week go outside with gloves and pick up garbage
3.Don't do it 
4.Put trash cans around the area

Idont know. i am in 6th grade si this is hard. wait let me serach it too lazy sorry
