Disciplinary Committee warning slogan

This is not a slogan that can be solved. Let's take some photos, see the whole picture of the disaster, see the whole picture of farmers' hard work, and then report the situation to the school. According to these circumstances, write a report to the school around this aspect, and let the school organize a discussion speech on students' extravagance and waste, so that students can realize that although wasting a grain of rice has little influence on the country and themselves, it is not a waste of rice if they do not pay attention to growing up when they are young. It may be a waste of a barrel of gasoline, a waste of a mine, or that one of you will become a leader in the future. Just because you don't pay attention to saving waste, it will cause food crisis, water crisis, crude oil crisis, mineral resources crisis and living space crisis in the whole country. According to the above, please write a paper about their understanding of food. With the enthusiasm of students.
