Reduce Waste on Campus Nowadays, with the improvement of our living standards, the phenomenon of waste is becoming more and more serious on campus. A lot of food is left after each meal; brand-new clothes are thrown away; electric appliances are not turned off when there are no people in the dormitories.
The habit of waste can cause a lot of problems. Though China is developing very fast, there are still a large number of people living under poverty. Furthermore, China has such a large population to support with such limited store of energy; waste may cause a disaster for the whole country. It can also have effect on the psychology of university students. They are not used to taking effort to cam their living, and they will keep this had habit during their whole life. How can our nation develop if every one of us keeps wasting
To form a good habit of economy is very important for everyone, especially for university students. We should try our best to protect the energy and resources of our country and our world. Please don’t leave food in your plate after finishing your meals; please don’t throw your clothes away when they are brand-new; please turn off the electric lamps whenever you leave the dormitory. By doing such routines in our daily lives, we can not only save resources but also give some help to the people who are not so well off as us.

Reduce Waste on Campus At present, among so many colleges, waste is a frequently found phenomenon. Take a Walk on campus, one may be shocked by the sight of various kinds of waste—intact main foodstuff dumped everywhere, intact clothes thrown in the dustbin, unnecessary things bought at will and so on. When going out with se-called friends, extravagant college students would prefer taxi to the bothersome crowded bus, buy themselves elegant dresses, especially girls, have meals in a higher-grade restaurant and indulge themselves in expensive bars. All these are a typical wasteful student’s life on campus.
It is the waste habit that will bring about many negative effects. First, it is a waste of money and a waste of other people’s laborious fruits. Uncountable taxpayers’ work makes the adolescents have the opportunity to receive higher education in universities. There’s no reason for them to waste time and money in self-enjoyment. Considering from the social perspective, it is a loss to the agricultural and industrial production when their work is mistreated and wasted. Apart from that, students who get used to wasting don’t know how to respect other people and their work and become arrogant gradually in every aspect of their daily lives on campus, If the case is to be so, it is a failure of modem education.
There are so many bad effects ff students develop a habit of waste, we should do something to put an end to this behavior. Consume when it is necessary, and never dump food in good condition or things still useful and so on. By conforming to these principles, we can learn to pay respect to others and their diligent work and become a more responsible person with a right sense of morality.
