Life science holds that biology is a living object, and the primary problem of life education is to teach young people how to know life scientifically and reasonably. After chemical evolution produced primitive life, biological evolution began, and human life was the result of this evolution. Macroscopically speaking, life is the movement form of protein and nucleic acid substances, and it is a special, advanced and complicated material movement form. Growth and development is the basic process of life, while metabolism is the most basic process of life and the basis of all other life phenomena. General life forms have some "purposeful" behaviors, while human beings, as advanced forms of life, have conscious and purposeful behaviors.

With the loss of some teenagers' material pursuit, the decline of social morality, the disharmony of physical and mental development, the waste of limited years and the frequent occurrence of suicide, China urgently needs to carry out life education:

1. Carrying out life education is the basic requirement to improve the overall quality of the people. Young students are the builders and successors of the future socialist cause, and their quality of life determines the future and destiny of the country and the nation.

2. Carrying out life education is an urgent requirement for the development and change of social environment. The development trend of economic globalization and cultural diversification, and the rapid development of modern science and technology and information technology provide favorable conditions for exchanges and cooperation between different nationalities and cultures, and provide a broad platform for students to obtain information, broaden their horizons and cultivate their skills. However, the following negative factors also affect the moral concepts and behavior habits of young students to some extent. The negative effects of hedonism, money worship and extreme individualism lead to the vague moral concepts of some students and the decline of their moral self-discipline ability.

3. Life education is a necessary condition to promote the healthy growth of young students. With the increasingly rich material life and complex social environment in modern society, the physiological maturity of young students is obviously ahead of schedule, which easily leads to the imbalance of physical, psychological and moral development. For a long time, due to the confusion in the process of physiological development, it is often difficult to cope with unpredictable and occasional hidden injuries, which leads to some students' psychological fragility, confusion and out-of-control behavior.
