Destroying the ecological environment brings disaster to mankind.
Eco-environmental problems refer to the interference and influence of human production activities and social activities on the eco-environment, which leads to disharmony or even opposition between various parts of the ecosystem, interferes with human normal life, and even threatens human survival in serious cases.
Status:
Environmental pollution is serious. Industrial wastes, especially the "three wastes" discharged by township enterprises and the unreasonable use of chemical products such as fertilizers and pesticides, are important reasons for rural environmental pollution. Due to serious pollution, the living environment of human beings has deteriorated, which seriously threatens human health and even survival.
Water resources are in short supply. China is a country short of water, and its per capita fresh water is only 1/4 of the world average, and its distribution is uneven. On the other hand, due to the serious water pollution, the already scarce water resources are even scarcer.
Soil fertility declines and cultivated land drops sharply. Due to the unreasonable use of a large number of chemical fertilizers, soil fertility has been declining, and the area of saline-alkali land and low-and medium-yield fields has been expanding.
Land desertification is serious. The unreasonable use of land by human beings, such as overgrazing grassland, unreasonable reclamation of grassland and woodland into farmland, and deforestation, has aggravated soil desertification and soil erosion.
The natural environment is harsh. Some rural residents in central and western China live in an environment of entering wasteland, which is not suitable for human survival.
On the other hand, because rural families occupy a large amount of cultivated land, township enterprises build factories, mine roads, and the cultivated land area has been shrinking.
The main causes of ecological and environmental problems:
Poor environmental awareness. People's awareness of ecological environment protection is not strong, and they don't have a deep understanding of the harm that destroying the ecological environment will cause to human beings.
Law enforcement is lax. In some areas, government organizations and other departments responsible for environmental protection have failed to stop acts that damage the ecological environment, and even condone such acts for immediate interests.
Cognitive error. Many places don't realize that the discharge of pollutants will do harm to the ecological environment, the earth and human beings. They didn't realize that a large amount of chemical fertilizer would reduce soil fertility and eventually worsen the soil. They didn't realize that a large amount of pesticides would pollute agricultural products and the environment.
Quick success and instant benefit. Some people who are eager for quick success and instant benefit ignore the long-term interests of the country and are unwilling to spend small money to control emissions, thus destroying the ecological environment.
Population pressure is great. China has a large population and less arable land per capita, so solving the problem of food and clothing is a top priority for the country. Although people realize that pesticides and fertilizers will damage the environment, because fertilizers play a 40% role in increasing grain production, without pesticides, pests and weeds will seriously threaten crops, so they have to use a lot of fertilizers and pesticides.
Solutions to ecological and environmental problems;
Strengthen publicity. Publicize the importance of the ecological environment and the harm that pollution will bring to mankind, and the whole people take action to actively prevent and control environmental pollution and protect the ecological environment.
Strict law enforcement. Strengthen law enforcement and severely crack down on acts that destroy the ecological environment, such as deforestation, land reclamation, discharge of "three wastes", environmental pollution, and indiscriminate occupation of cultivated land.
Pay attention to organic fertilizer. Scientific application of organic fertilizer and chemical fertilizer can increase production without reducing soil fertility.
Advocate ecological agriculture. Eco-agriculture refers to an agricultural production system that uses the principles of biological regeneration and material circulation in the ecosystem, adopts systematic engineering methods, absorbs modern scientific achievements, and rationally organizes agricultural, forestry, animal husbandry, sideline and fishery production according to local conditions to achieve coordinated development of economic, social and ecological benefits.
Adopt scientific methods, give priority to prevention and combine prevention with treatment. We should use effective science and technology to prevent and control the ecological environment.
