People live in the natural environment, which is the basic condition for human survival and the material source for developing production and prospering economy. Without the vast natural environment of the earth, it is impossible for human beings to survive and reproduce. With the rapid growth of population, the development of productivity and the rapid development of science and technology, the waste discharged from industry and life is increasing day by day, which makes the pollution of atmosphere, water quality and soil increasingly serious, the natural ecological balance has been severely impacted and destroyed, and many resources are decreasing day by day and are in danger of exhaustion. Soil erosion and land desertification are becoming more and more serious, and food production and human health are seriously threatened. Therefore, maintaining ecological balance and protecting the environment are fundamental issues related to human survival and social development.
Question 2: What is the meaning and classification of environment? The word environment first appeared in the Biography of Yu Que, the Yuan history of China. From a philosophical point of view, the environment is an object that exists relative to the subject. For environmental science, the environment refers to the sum of the external world with human beings as the main body, that is, the synthesis of various natural factors and social factors on which human beings depend for survival and development.
Environment can also be called humanistic environment. According to system theory, it can be called human environmental system. It refers to physical systems (sunlight, air, water and soil), biological systems (human beings, animals, plants and microorganisms) and socio-economic systems. These three systems interact through the flow of energy and the circulation of matter. The environment clearly defined by law is limited to "natural factors" that must be protected by law.
Classification: Environment can be divided into natural environment and artificial environment according to the formation of environmental elements.
The natural environment, also known as nature, is a native environment, a native environment. The natural environment refers to the sum of all kinds of natural substances and energy, such as atmosphere, water, soil, solar radiation and biology, which have a direct or indirect impact on human survival and development. These environmental factors constitute a natural environmental system that is interrelated and mutually restricted. Geographically speaking, the environment can be called the sum of the earth's environment and its space environment, which can be divided into four layers, namely, hydrosphere (rivers, lakes, oceans and groundwater), rocky PEDOSPHERE (soil, mountains and mineral deposits), atmosphere (about 2000 kilometers from the earth's surface to the atmosphere) and biosphere (the part of the earth where life exists).
Artificial environment, also known as artificial environment, or artificially transformed environment, is an environment created by human beings through the transformation or processing of human labor on the basis of natural environment in order to improve material and cultural life, so it is called secondary environment. Such as cities, residential areas (living quarters), villages, reservoirs, places of interest, scenic spots and so on.
According to the size of the environmental scope, it can be divided into cosmic environment, geological environment, geographical environment, urban and rural environment and indoor environment. All environments relative to indoor environment can be called outdoor environment.
Question 3: What is the significance of environmental remediation? In social investigation, the significance of environmental improvement in a village lies in improving people's awareness of environmental protection and leading a moderate life. The significance of environmental remediation is to give us a clean and comfortable environment! The purpose of the method is a healthy life!
Question 4: What is the environmental significance of new energy? 1. Reduce the proportion of traditional fossil energy such as coal and oil in the energy structure, reduce the emission of carbon dioxide and pollutants, and reduce environmental pollution;
2. To deal with the energy problem after the exhaustion of traditional fossil energy, compared with traditional fossil energy, clean new energy sources such as solar energy and wind energy are inexhaustible;
3. The development of new energy can effectively slow down the over-exploitation of traditional resources, provide a buffer period for the deteriorating environment and curb the further deterioration of the environment;
4. Reduce human health problems such as diseases caused by environmental degradation.
