Environment is the living space of human beings, including not only the natural environment, daily life, study and work environment, but also the scientific allocation and use of modern daily necessities. Environmental pollution not only affects the sustainable development of China's social economy, but also affects the safety, health and quality of life of the people, which has attracted more and more attention. Only through the joint efforts of the whole society, effectively control environmental pollution and continuously improve environmental quality can we breathe clean air, drink safe water, eat safe food and have a safe working and living environment.
Environment refers to the external world with human beings as the main body, which is the unity of various natural and social factors that matter and phenomena interact with human beings on the earth, the material basis for human survival and development, and an important condition closely related to human health. People's life is always in a certain natural environment, social environment and man-made environment, and is often influenced by both material and spiritual factors. In order to survive and develop, improve the quality of life and maintain and promote health, human beings need to make full use of various resources in the environment. However, due to natural factors and human social behavior, the environment will be destroyed and human health will be affected. When this kind of injury and influence is within a certain limit, the adjustment function of environment and human body has the ability to restore the unbalanced state to its original state. If it exceeds the limit that the environment and the body can bear, it may cause ecological imbalance and damage to the physiological function of the body, and even lead to short-term and long-term harm to human health. Therefore, human beings should improve environmental awareness, recognize the relationship between environment and health, standardize social behavior (prevent environmental pollution, maintain ecological balance, and promote the development of environmental ecology to a virtuous circle), establish laws and standards for environmental protection, and avoid environmental degradation and imbalance. This is an important criterion for correctly handling the relationship between human beings and the environment.
