With the rapid development of economy, environmental protection has become more and more important. Since the reform and opening up, China's economy has developed rapidly, and many high-rise buildings have sprung up, but we have paid a huge price for resources and environment, and the contradiction between economic development and resources and environment has become increasingly acute. This situation is directly related to the unreasonable economic structure and extensive growth mode. If we don't speed up the adjustment of economic structure and change the growth mode, resources can't support it, the environment can't accommodate it, the society can't afford it, and economic development can't be sustainable. Only by adhering to economical development, clean development and safe development can we achieve sound and rapid economic development. At the same time, greenhouse gas emissions lead to global warming, which has aroused widespread concern in the international community. Further strengthening energy conservation and emission reduction is also an urgent need to cope with global climate change.
Energy conservation and emission reduction refers to reducing energy waste and reducing exhaust emissions. Due to people's insufficient expectation of the negative impact of highly developed industries and unfavorable prevention, three global crises have resulted: resource shortage, environmental pollution and ecological destruction. Humans constantly discharge pollutants into the environment. However, due to the diffusion, dilution, redox and biodegradation of atmosphere, water and soil, etc. The concentration and toxicity of pollutants will naturally decrease, which is called environmental self-purification. If the discharged substances exceed the self-purification capacity of the environment, the environmental quality will change adversely, endangering human health and survival, thus leading to environmental pollution. In recent years, environmental pollution has become increasingly serious, and the situation of achieving the goal of energy conservation and emission reduction is very grim. From 65438 to 0989, the National Congress investigated 854 towns, and the daily discharge reached 36.53 billion tons, including 550 million tons of industrial wastewater. Most of these wastewater are discharged directly without treatment, which pollutes rivers, lakes and oceans. In the first quarter of 2004, 24 provinces and cities in China were seriously short of electricity, and the power shortage problem faced the most serious moment in 20 years. The national coal supply gap is huge, and coal consumption in various places is tight. More than 420 cities in China are short of water supply. The relative shortage of water resources has increasingly become a prominent contradiction restricting development. Electricity, coal and water are in a comprehensive emergency, and energy saving is imminent.
China's "Eleventh Five-Year Plan" outlines that during the "Eleventh Five-Year Plan" period, the energy consumption per unit of GDP will be reduced by about 20%, and the total discharge of major pollutants will be reduced by 10%. This is an important measure to implement Scientific Outlook on Development and build a harmonious socialist society. It is an inevitable choice for building a resource-saving and environment-friendly society; It is the only way to promote economic restructuring and change the growth mode; It is an inevitable requirement for safeguarding the long-term interests of the Chinese nation.
Energy conservation and emission reduction should start from small things, and everyone should work together to create a beautiful home. We can take the following feasible suggestions:
First, save electricity. Pay attention to turn off the lights when you leave, and you can use efficient and energy-saving light bulbs. According to the estimation of the U.S. Department of Energy, replacing traditional light bulbs with energy-efficient light bulbs can reduce 400 million tons of carbon dioxide emissions. In addition to electric lights, we should also pay attention to the use of other electrical appliances, try to choose low-consumption and energy-saving products, cut off or turn off the power supply when not using electrical appliances, and keep the refrigerator frost-free. When the weather is not very hot in summer, it is best to use fans or electric fans instead of air conditioners. When using the air conditioner, don't adjust the temperature too low, just about 26℃.
Second, save water resources. Many wastewater can be recycled. The water for washing face, hands, vegetables, baths and clothes can be collected to clean the floor, flush the toilet and water the flowers. Taomi water is a good detergent, so you can stay to wash dishes and chopsticks. Pots and plates stained with oil should be cleaned with used napkins first, which saves water and is convenient to clean. You can also use less detergent to reduce water pollution.
Third, save paper. The recycling of paper can avoid methane released by landfill and reduce the felling of trees. According to statistics, recycling one ton of waste paper can produce 800 kilograms of recycled paper, which can reduce the felling of 17 trees. Saving paper is to protect forest resources and the environment.
Fourth, reduce tail gas emissions. Traffic waste gas and industrial waste gas are the main sources of domestic waste gas. Try to go out by bus or taxi, or by bike, and try to take fewer private cars. The city is filled with smoke from burning garbage and goods produced by factories. They should treat and filter the waste gas and then discharge it to reduce pollution. Plants can absorb carbon dioxide and then release oxygen, so we should plant many trees, especially on the roadside.
Five, garbage classification and treatment. Garbage sorting can recycle valuable resources and reduce the energy consumed by landfill and incineration. For example, waste paper is sent directly to a paper mill to produce recycled paper; Disposable commodities such as beverage bottles, cans and plastics can also be sent to related factories to become renewable resources; Household appliances can be sent to specialized manufacturers for decomposition and recycling. Different garbage bags can be prepared at home to collect waste paper, plastics, packaging boxes and so on. Classify and recycle garbage every day, and try to turn waste into treasure.
Some people say it well: the main body of society is people, and the main body of energy conservation and emission reduction must also be people. Energy conservation and emission reduction must start from everyone. Yes, if we want to live in a beautiful and harmonious world, we should not only realize the importance of environmental protection, but also put it into action. Therefore, we should join hands to create our beautiful life together; Let's take action, save energy and reduce emissions, save the fate of the earth's homeland, and maintain a future in which mankind will continue to survive!
