All human activities are inseparable from the environment. With the development of science and technology, the role of human beings on the environment is getting wider and wider, the influence degree is getting deeper and deeper, and the pollution and ecological damage to the environment are getting bigger and bigger. At the same time, the reaction of the environment makes global environmental problems penetrate into every aspect of our daily life. In this regard, everyone should take action to solve environmental problems.
Responsibility.
Since mankind entered the period of industrial civilization, the scientific level has been rapidly improved, the population has expanded rapidly, and the economic strength has been unprecedentedly improved. Human beings have carried out unprecedented large-scale development and utilization of natural resources, which has brought a series of environmental problems, including global warming, oxygen layer destruction, air pollution, acid rain and so on.
Since the industrial revolution, mankind has burned a lot of fossil fuels, such as coal, oil and natural gas. A large number of greenhouse gases such as carbon dioxide are discharged into the atmosphere, and the enhanced greenhouse effect will aggravate climate warming. A direct consequence of global warming is the melting of glaciers and the thermal expansion of seawater, which leads to the rise of sea level. With the accelerated temperature rise, it is predicted that by 2 100, some coastal lowlands, coastal cities and some island countries will face the threat of being submerged, and sea level rise will also lead to furniture storms and floods, leading to the failure of urban sewage systems; Seawater intrusion leads to salinization of land and farmland.
* Excessive use of chlorofluorocarbons is the main reason for destroying the ozone layer. Chlorofluorocarbon (CFC) is a man-made chemical substance, which was put into production by DuPont Company of the United States on 1930. After World War II, especially after 60 years, it began to be widely used, mainly as aerosol, refrigerant, foaming agent, chemical solvent and so on. In addition, halons (used in fire extinguishers) and nitrogen oxides can also cause ozone layer depletion. The destruction of the ozone layer will increase the ultraviolet rays of the earth. Ultraviolet rays can destroy biomolecules including DNA, increase the risk of skin cancer and cataract, and are related to many immune system diseases. The plankton in the ocean is fatally affected, the marine ecosystem is destroyed, the crop yield is reduced, and the greenhouse effect is strengthened.
* Air pollution is mainly related to carbon monoxide and nitrogen oxides in automobile exhaust, as well as sulfur oxides and soot produced by coal burning. Acid rain caused by air pollution is an environmental problem after 1950s. Sulfur-containing pollutants discharged from factories enter the atmosphere and combine with water vapor to form sulfurous acid and sulfuric acid, which makes the precipitation show strong acidity, and the bottom is acid rain. Acid rain destroys forests and acidifies lakes; Corrosion of buildings, plastics and metal facilities; Acidify the soil, thus affecting crop growth and reducing yield. China's Chongqing, Sichuan, Guizhou, Guangdong, Guangxi, Jiangsu, Jiangxi, Zhejiang and other provinces and cities south of the Yangtze River are seriously polluted by acid rain.
During this period, environmental problems have risen to a major issue that fundamentally affects the survival and development of human society, endangering the survival of all mankind, and the contradiction between man and land has intensified sharply.
In order to solve this problem and seek harmony between man and land, we must stick to the road of sustainable development.
The development that not only meets the needs of contemporary people, but also does not damage the ability of future generations to meet needs is called sustainable development. Adhere to sustainable development, we must follow three principles: fairness, sustainability and * * * same sex.
Adhering to sustainable development means creating new modes of production, new modes of consumption, new rules of social behavior and new modes of development. This requires us to change our ideas, adjust our behavior and strengthen international cooperation.
The concepts that need to be changed are development view, resource view, environment view, ethics view and consumption view.
The concept of sustainable development holds that economic growth is only a part of development, and it is one-sided to replace development with economic growth. The concept of sustainable development pursues social progress, improvement of people's living standard and all-round development of people, including improvement of environmental quality, harmony among people, improvement of people's spiritual accomplishment, improvement of social fashion and progress of science and technology. ※.
The values of sustainable development require human beings to re-recognize and evaluate the value of nature to human beings and consider it in the economic accounting system. ※.
According to the requirements of sustainable development, in order to achieve sustainable economic growth, we must pay attention to the application methods of energy and raw materials, so as to reduce losses, put an end to waste, try not to let waste enter the environment, and reduce the pressure on the environment. ※.
From the perspective of sustainable development, it is also necessary to deal with the ethical issues of the relationship between human beings and other creatures. Man must keep a harmonious and balanced relationship with other creatures. ※. If this relationship is destroyed, the food chain on which human beings depend will be destroyed and human survival will be affected.
Traditional consumption concept is an important reason for resource shortage, environmental pollution and ecological destruction. Sustainable development requires people to change the traditional mode of production and consumption, to invest as little as possible, to produce as much as possible, to use as much as possible and to emit less. ※.
Regulation behavior mainly refers to government behavior, market behavior and public behavior.
The adjustment of government behavior mainly includes: implementing laws on environmental protection; Give priority to pollution prevention and control to control the occurrence of pollution; Vigorously develop environmental protection industry; Calculate the carrying capacity of resources and environment in a certain area; Improve the collection of various environmental taxes and fees; Strengthen the management of natural resources development and utilization; Strengthen the environmental supervision and management of products; Establish a comprehensive decision-making mechanism for environment and development.
The adjustment of market behavior mainly includes: changing terminal management into whole process cleaner production; Implement scientific management; The business objectives of the industry take into account the three major objectives of economy, society and environment; Planning enterprise development strategy; Specific and feasible environmental behavior standards are integrated into employee evaluation, reward and punishment mechanism; Reduce waste in the circulation field.
The adjustment of public behavior includes: actively participating in environmental protection activities; Use environmentally friendly products; Less over-packaging, advocating simple life; Popularize environmental protection knowledge; Realize garbage packaging and so on.
Implementing the strategy of sustainable development means the economic and social development process of a country or region. It is a major strategic change to change from the traditional business model to a new model with great changes. At the same time, the implementation of sustainable development strategy needs to establish a true global partnership. Agenda 2 1 Century clarifies the principle of "common but differentiated" responsibility of all countries in the world to protect the earth.
Taking the road of sustainable development is the most profound social change in human history, and its success or failure is related to the survival or extinction of human species. Each of us is changing the global environment with our own way of life and consumption. Therefore, we propose:
Save resources and reduce pollution;
Recycling waste products;
Green consumption, buying environmental protection products;
Cherish life and everything will survive.
Realize the coordinated development of humanities and geographical environment. We must stick to the road of sustainable development. We must understand the main environmental problems that human beings are facing at present, know the roots of these environmental problems, and then understand that it is an inevitable choice for human beings to take the road of sustainable development.
