We can say that if we disseminate a seed it take 120 days ripe and we can organise a group inside the class and in the school campus and make the students to understand the importance of food items
Throwing food items in dustbin is not a good habit, other students should stand up raise voice against this and discourage this. They should talk to teachers for help so that the teachers take strict action towards this, the students could also program an event to make students aware that food is not for throwing, many people die in country because of lacking food, we are fortunate that we get food and thank god for this. We should give left food to needy people.
