NeedDefinition and Function"Need" is a word that expresses the necessary requirements for survival and development. It refers to the minimum requirements that people must meet in order to survive, such as food, clothing, housing, medical care, education, etc. "Need" is a kind of minimum threshold to maintain human life activities, and it is a necessary condition for human survival and reproduction.Types of NeedsNatural needs refer to the essential needs of human survival, including food, clothing, housing, medical care and other aspects. These needs have a direct relationship with human survival and reproduction, so they are called natural needs. Natural needs have the characteristics of inevitability, urgency and difficulty to change, which are the basic requirements of human survival.Social needs refer to the requirements of people for social life and development. These needs include education, culture, entertainment, social security and other aspects. Social needs are the result of social civilization development, and they play an important role in promoting social progress and development. Social needs have the characteristics of variability, priority selection and controllability.Satisfaction of NeedsThe satisfaction of needs has a hierarchical structure, which is called the hierarchy of needs. The hierarchy of needs divides human needs into five levels: physiological needs, safety needs, love and belonging needs, self-esteem needs and self-actualization needs. These five levels constitute a need pyramid, with physiological needs as the foundation, self-actualization needs as the peak, and other needs interpolated in between.The process of satisfaction of needs includes three stages: physiological needs satisfaction stage, psychological needs satisfaction stage and self-realization needs satisfaction stage. In the physiological needs satisfaction stage, people pay attention to whether their basic requirements such as food, clothing, housing and medical care are met; in the psychological needs satisfaction stage, people pay attention to whether they can obtain emotional support and recognition from others; in the self-realization needs satisfaction stage, people pay attention to whether they can achieve their potential and goals.Limitations of Needs SatisfactionThe satisfaction of needs requires resources support. However, resources are limited in quantity and distribution uneven. This limits the satisfaction of human needs. For example, although the number of people is increasing in absolute terms worldwide, but in some countries and regions, resources such as food, water and medical care are insufficient. People may face life-threatening challenges when resources are insufficient.Technology development can improve resource utilization efficiency and create new resources to meet human needs. However, technology development is also limited by factors such as economic conditions and scientific and technological level. When technology cannot meet human requirements for resources or production efficiency, it will also lead to the failure to meet human needs.
