Small batteries have penetrated into every corner of our lives, and their usage is increasing rapidly: mobile phones, cameras, tape recorders, walkmen, four-wheel drive racing cars and other electric toys are inseparable from it. As a primary school student, we learned a lot about the harm of used batteries from textbooks and other aspects. For example, if a battery 1 rotted underground, the soil 1 m2 would lose its use value forever; A grain of button cell can pollute 600 tons of water, which is equivalent to a person's drinking water for a lifetime. Among several substances that pose the greatest threat to the natural environment, batteries contain many kinds of mercury, lead and cadmium. If waste batteries are mixed with domestic garbage and buried, or discarded casually, the leaked mercury and heavy metals will seep into the soil, pollute the groundwater, enter fish and crops, destroy the living environment of human beings and indirectly threaten human health.

The harm of waste batteries can not be ignored. People have come up with many good ways to reduce the potential harm of waste batteries, such as setting up separate recycling bins for batteries and other wastes, and rewarding those who recycle batteries in some battery production units and shopping malls. However, observing the real life, there are few facilities for garbage sorting, that is, there are facilities for garbage sorting in some places, and it is difficult for people to achieve the effect of garbage sorting. Some battery production units engage in the way of recycling used batteries with prizes, which is not lasting and can only be seen once in a long time. In some shopping malls, grandparents take prizes to participate in the collection of used batteries, but they are not the main force in using batteries, and the effect is limited.

Can't the good method of sorting and recycling waste batteries achieve good results? I have a good suggestion: who will do it? For example, it is more effective to mobilize and encourage students to become the main force in recycling used batteries. The reasons are as follows: First, students are the main users of batteries, including college students, primary and secondary school students and kindergarten children. They mainly use MP3 players, walkmen, tape recorders, cameras, electric toys and mobile phones. Second, students are also the main force in caring for and protecting the environment. They have the responsibility and ability to undertake the activities of collecting old batteries. Third, unlike all kinds of garbage in residential areas, the old battery boxes in schools are easy to classify; Fourth, with reasonable guidance and support, schools, classes and students should strive to be small messengers to protect the environment and enhance their sense of honor.

The specific methods are as follows: let every family with students know that "I will do battery recycling" is a social work that students are proud of; If some battery manufacturers and shopping malls also reward people who recycle batteries, they can be used to reward schools, classes and students; Some units that have close contact with students can also provide some incentives, such as preferential sales of books in Xinhua Bookstore, free opening of children's activity centers and museums, visiting some children's tourist attractions, and encouraging schools, classes and students who have done well in collecting used batteries.

The campaign slogan is: I want to recycle batteries, yeah!
