It is common sense that human beings cannot be above nature, but the price is quite heavy. The Loess Plateau and the Qinghai-Tibet Plateau had a large area of temperate rainforest climate in prehistoric times (about 4000 years ago). At that time, natural resources were extremely rich, virgin forests were dense, and birds and animals were all kinds. The climate is warm, suitable for the growth and reproduction of various animals and plants, and also suitable for human survival and reproduction. With the passage of time, the local ecological balance has been broken due to the endless destructive activities of human beings, coupled with the failure of nature's ability to repair and various harsh climate events, forcing human beings to gradually leave this area that has been unable to survive normally. This is a distressing and destructive process caused by human activities. With the progress of society and the development of science and technology, especially since the industrial revolution in the18th century, the ability of human beings to exploit and utilize natural resources has been continuously improved, fuel consumption has increased sharply, underground mineral deposits have been mined and smelted in large quantities, and the industry is highly developed, which has promoted the great development of industry and agriculture and brought great wealth to mankind. At the same time, due to the unreasonable exploitation of natural resources, the great development of industry and agriculture, and the production and use of a large number of chemicals such as pesticides and fertilizers, a large number of productive wastes (waste water, waste gas and waste residue) and domestic garbage continue to enter the environment, seriously polluting the natural environment such as atmosphere, water and soil, destroying the normal ecological environment, reducing the quality of people's living environment and directly threatening human health. Especially in the past 100 years, dozens of serious public nuisance incidents caused by environmental pollution have occurred all over the world, such as the soot-type smog incident in London, England, the photochemical smog incident in Los Angeles, the chronic methylmercury poisoning in Minamata Bay, Japan, and the chronic cadmium poisoning in Shentongchuan Basin. 1984 65438+On February 3, 2008, the toxic gas of methyl isocyanate leaked from pesticide plant, Pablo, India, causing serious environmental pollution, poisoning tens of thousands of people and thousands of deaths, and causing serious damage to the local ecological environment. 1The explosion of Chernobyl nuclear power plant (now located in Ukraine) in the former Soviet Union on April 26th, 986 not only posed a great threat to contemporary human health, but also caused serious harm to future generations and the ecological environment.
Human activities not only greatly affect the balance of the natural environment, but also constantly threaten their own security. It is gratifying that more and more people have realized this problem now. We are constantly reducing activities that seriously damage the environment, and at the same time we have made some achievements in managing the environment.
Recently, some media reported that the Mu Us Desert, also known as Ordos Sandy Land, is located at the junction of Shaanxi and Inner Mongolia provinces. It is one of the four sandy lands in China with a total area of 42,200 square kilometers. It is a relatively young desert, which gradually developed into its present scale in one or two thousand years. At first, sandstorms began to accumulate here in the Tang Dynasty, and it was not until the Ming and Qing Dynasties that a vast desert was formed. Sand control began about 40 years ago, and now the area of sand control has reached 50 million mu, about 33 thousand square kilometers. 80% of the Mu Us Desert has been treated, and soil and water are no longer lost. The annual sediment discharge of the Yellow River has been reduced by 400 million tons. Today, the vegetation coverage rate of Mu Us Desert has reached 30%. Due to the good precipitation, modern biotechnology and scientific grazing management, Mu Us is likely to become grassland and farmland. There is no doubt that turning desert into grassland and farmland proves that human beings can also have a positive impact on nature.
To realize the sustainable development of society, first of all, for individuals, we should attach importance to the concept of environmental protection. At present, people's living environment needs everyone's efforts and contributions to improve. We should start from the small things around us, stop littering and trampling on the lawn, stop others from damaging the environment, be a law-abiding and environmental-friendly citizen, and do our bit to protect the ecological environment in China. At the same time, in order to deepen the sustainable development, people can also achieve the purpose of environmental protection by changing the way of travel, and can reduce the rate of private car travel and travel on foot or by bus. Reducing automobile exhaust emissions can effectively improve air quality and reduce the occurrence of haze weather.
For the relevant government departments, we should pay attention to the supervision of enterprises with serious environmental pollution and conduct regular supervision and audit of these enterprises with serious environmental pollution. Many industrial enterprises often discharge pollutants that meet the requirements during the day and begin to exceed the standard at night. Government departments should pay attention to the inspection of industrial enterprises at night to ensure the sustainable development of industrial enterprises.
From the national point of view, the state should establish comprehensive and effective laws, regulations and policies to limit the heavily polluted industrial sectors, for example, it can limit higher pollution discharge standards, so that the industrial sectors can deeply treat the polluted gases when discharging toxic gases, thus effectively ensuring the ecological environment. The state should also invest some money to develop new low-carbon living technologies, so that the concept of sustainable development can really play a positive role in protecting the ecological environment.
