World Environment Day Manuscript of Grade One (3) Basic knowledge of environmental protection

1. Environment: refers to the sum of natural and artificially modified natural factors that affect human survival and development, including atmosphere, water, ocean, land, mineral deposits, forests, grasslands, wildlife, cultural relics, nature reserves, scenic spots, cities and villages, etc.

2. Environmental problems: refers to the environmental changes that are not conducive to human survival and development caused by human behavior to the surrounding environment in the process of production and life. It includes ecological destruction, resource depletion and environmental pollution.

3. Environmental protection: refers to various actions taken by human beings to coordinate the relationship between human beings and the environment, solve real or potential environmental problems and ensure the sustainable development of human society and economy.

4. Environmental pollution: refers to the phenomenon that harmful substances produced by human beings in the process of production and life are discharged into the environment, thus endangering the survival and development of human beings and other organisms.

5. Ecological destruction: refers to the phenomenon that the structure and function of the survival and development system of human beings and other organisms are destroyed due to the unreasonable development and utilization of natural resources by human beings, which endangers the survival and development of human beings and other organisms.

6. Ten major environmental problems in the world today: climate warming, ozone layer destruction, biological species reduction, acid rain spread, forest decline, land desertification, air pollution, water pollution, marine pollution and solid waste pollution.

7. Sustainable development: refers to continuously improving people's quality of life and environmental carrying capacity, and meeting the needs of contemporary people without damaging the ability of future generations to meet their needs; Meeting the needs of people in a region or a country does not harm the development of people's ability to meet their needs in other regions or countries. In short, we should not simply pursue immediate development, regardless of future generations, but adopt a strategy based on protecting the environment and ensuring the sustainable development of all mankind.

8. The main environmental problems in China are: (1) dust and acid rain caused by air pollution caused by coal burning; (2) per capita water resources are short and water pollution is serious; (3) Forests and vegetation are destroyed and natural disasters occur frequently; (4) Serious soil erosion and land desertification; (5) The decrease of biological population.

9. The main reasons for China's environmental problems are (1) excessive population pressure (2) rapid growth of intensive economy (3) rapid development of urbanization (4) unreasonable economic structure (5) insufficient investment in environmental protection (6) improper comprehensive decision-making on environment and development (7) weak environmental management capacity (8) lagging environmental legal system.

10. Environmental protection in China: environmental protection with industrial pollution prevention as the guide and comprehensive improvement of urban environment as the focus started; Environmental protection with emphasis on land basin improvement and rural ecological environment protection has been comprehensively promoted; Implement a sustainable development strategy aimed at ecological environment protection and rational utilization of resources.

1 1. Three principles of industrial pollution prevention and control in China: prevention first, combination of prevention and control, and comprehensive management; Whoever pollutes will be treated; Strengthen environmental management.

12. Main types of environmental pollutants: The pollution caused by human activities includes waste gas, waste water, waste residue, dust, malodorous gas, radioactive substances, noise, vibration and electromagnetic wave radiation.

13. Pollution sources and their classification: all equipment, devices and places that can generate and discharge physics (sound, light, heat, vibration, radiation, etc.). ), chemical and biological harmful substances or energy are called pollution sources. Pollution sources can be divided into natural and man-made: man-made pollution sources are divided into industrial pollution sources, domestic pollution sources, traffic pollution sources and agricultural pollution sources.

14, water resources and water resources protection: water resources refer to all surface water and groundwater that can be used for human production and life. The laws and regulations for protecting water resources in China are as follows:

(1) Strictly manage and save industrial water, agricultural water and domestic water;

(2) Rational exploitation of groundwater to prevent land subsidence;

(3) The discharge of sewage into water bodies must meet the national standards;

(4) It is forbidden to dump garbage and waste residue into water;

(five) it is forbidden to use seepage pits, wells, cracks, ditches and caves to dump toxic and harmful sewage and other toxic and harmful wastes.

15, World Environment Day: 1972, the United Nations held the first "conference on human environment" in Stockholm, Sweden, and 1 13 countries (including China) participated in the conference. The Declaration on the Human Environment was adopted at the meeting. Since then, environmental protection has played an irreplaceable role in the survival and development of all mankind, and a consensus has been reached to take unified action to jointly protect the environment for human survival. In the same year, the United Nations General Assembly decided that June 5th, the opening day of this conference, was the "World Environment Day". In the future, every year on June 5th, all countries in the world will carry out mass publicity and commemorative activities on environmental protection, so as to arouse people all over the world to pay attention to and protect the environment on which human beings depend, take actions consciously, participate together and create a beautiful home. Every year, World Environment Day has a specific theme. This year's theme is: 2000- Environmental Millennium-Let's act!

16, ecological agriculture: refers to a comprehensive agricultural production system that is intensively managed according to ecological principles. The main contents include: avoiding excessive use of chemical fertilizers and pesticides in agricultural production, causing land resources destruction and wildlife reduction, polluting water bodies and endangering human health, instead of protecting the environment, reducing pollution, comprehensively utilizing and saving resources, and realizing the sustainable development of agricultural production methods.

17. Hygienic standard for drinking water: (1) Good sensory properties (2) Toxic substances should be harmless to human body (3) No pathogenic microorganisms are allowed (4) Normal pH value.

Benefits of establishing a "green school": improving teachers' and students' environmental literacy such as environmental knowledge, awareness, skills, attitudes, values and behaviors, and improving the level of environmental education, teaching and management are conducive to the school's own development.

19, meaning of green school: A green school is a school that implements environmental education for sustainable development.

20. Environmental pollution and destruction accidents: refer to unexpected events that cause environmental pollution, destroy wild plants and nature reserves protected by the state, endanger human health, cause social economic and people's property losses, and cause adverse social impacts due to economic and social activities that violate environmental protection laws and regulations, as well as the influence of unforeseeable factors or irresistible natural disasters.

2 1. Organic pollution of water body: mainly refers to the pollution caused by wastewater containing a large amount of organic matter discharged from urban sewage, food industry and paper industry. These pollutants need to consume a lot of dissolved oxygen in the process of biological oxidation and decomposition in water. Once the oxygen supply in water is insufficient, it will stop oxidation, resulting in anaerobic fermentation of organic matter, giving off stench, polluting the environment and poisoning aquatic organisms.
