There are many reasons, which can be analyzed from the following points: First, the pollution of industrial emissions, industrial waste gas, and wastewater are important reasons. This has something to do with the irrational industrial structure.
Second, life pollution, a large population, a lot of domestic waste, daily life brings a lot of pressure to the environment. Third, man-made damage to the environment, because people's awareness of environmental protection is not very strong, there are often man-made damage to the environment. Not conducive to sustainable development.

1. Air pollution.
Sulfur dioxide in our country.
It ranks first in the world in terms of emissions. Air pollution is currently the number one environmental problem in China.
2. Water environment pollution.
The pollution degree of the seven major water systems in China is in order: Liaohe River.
Haihe River, Huai River.
Yellow River, Songhua River.
In the Pearl River and the Yangtze River, 42% of the water quality exceeds the Class 3 standard (cannot be used as a source of drinking water), and 36% of the urban river sections in the country are inferior to Class 5 water quality and have lost their use function. The water quality of large freshwater lakes (reservoirs) and urban lakes is generally poor, and more than 75% of the lakes have increased eutrophication, mainly caused by nitrogen and phosphorus pollution.
3. Garbage disposal problems.
At present, the comprehensive utilization rate of industrial solid waste in China is about 46%. Less than 10% of the country's municipal solid waste meets the requirements for harmless treatment. White contamination from plastic packaging and agricultural films.
It has spread throughout the country.

Environmental pollution problems.
China's environmental development has always attracted much attention. Although the people have taken a series of measures to improve the environment, the problem of environmental pollution still exists. Problems such as air pollution, water pollution, and soil pollution have become important factors restricting China's development and development.
To solve environmental problems, we need to work together with the people. ** We should increase investment in environmental protection, formulate stricter environmental protection laws and regulations, severely punish illegal enterprises, and strengthen the supervision and management of environmental protection work. People should increase their awareness of environmental protection, reduce pollutant emissions, and adopt a more environmentally friendly lifestyle.
In addition, we also need to strengthen the research and development of environmental protection technology, develop new energy industries, and promote environmentally friendly products. Only with the joint efforts of the people, the people, and science and technology can we achieve a win-win situation for the environment and the economy, make our homes more beautiful, and make our future more sustainable.
Resource utilization and management.
With the rapid development of the economy, China's environmental problems have become increasingly prominent. Pollution, energy consumption, resource waste and other problems have become important factors restricting China's sustainable development. In order to address these problems, the use and management of resources must be strengthened.
First, we need to change the way we use resources. China's resource utilization rate is relatively low, and it is necessary to improve resource utilization through technological innovation and management innovation.
For example, strengthening recycling and developing clean energy are all worthy directions. At the same time, it is necessary to strengthen the management of resources, formulate a scientific resource management system, standardize the behavior of resource utilization, and curb the phenomenon of waste. Second, we need to focus on environmental protection.
Environmental pollution has become an important factor restricting China's sustainable development, and environmental protection must be strengthened. It is necessary to strengthen environmental monitoring, improve the environmental governance and restoration system, strengthen the implementation of environmental protection laws and regulations, and improve public awareness of environmental protection. In short, resource utilization and environmental protection are the key issues for China's sustainable development.
Only through scientific management and technological innovation can we achieve sustainable use of resources and sustainable development of the environment.
Ecological protection and construction.
The issue of environmental development in our country is a long-term and arduous task. With the rapid development of industrialization and urbanization, environmental pollution, waste of resources, ecological damage and other problems have become increasingly prominent, which have brought great harm to people's production and life. Therefore, ecological protection and construction are particularly important.
We must take effective measures to strengthen environmental protection and ecological construction to achieve sustainable development. Specifically, we should strengthen environmental monitoring and management, strictly enforce environmental laws and regulations, crack down on environmental violations, promote environmental protection science and technology, and strengthen environmental protection publicity and education. In addition, it is also necessary to strengthen ecological construction and improve the ecological environment.
This includes promoting the ecological protection and construction of forests, grasslands, wetlands, etc., strengthening the protection and management of water resources, and promoting clean energy. Only in this way can we achieve a win-win situation for economic development and ecological protection, and let people live in a better environment.

1. Global warmingGlobal warming:
Over the past 100 years, the global average temperature has experienced two fluctuations, cold and warm, and the overall trend can be regarded as an upward trend. In the eighties, global temperatures rose significantly. 1981 The average global temperature in 1990 was higher than it was 100 years ago.
2. Shortage of resources and energy
At present, the problem of resource and energy shortages in the world has emerged in most countries and even on a global scale. The emergence of this phenomenon is mainly caused by unplanned and unreasonable large-scale exploitation by human beings. In the early nineties of this century, the total energy consumption of the world was about 10 billion tons of standard coal, and by 2000 energy consumption will double.
3. Sharp decline in forests
Forests are an important part of the ecosystems on which human beings depend. Once 7.6 billion hectares of forests on Earth, it fell to 5.5 billion hectares this century and 2.8 billion hectares by 1976. Due to the growth of the world's population, the demand for arable land, pasture, and timber is increasing, which has led to excessive logging and reclamation of forests, causing unprecedented damage to forests.
4. Accelerated extinction of species:
There are 500 10 million species of organisms living on Earth today. In general, the rate of extinction of species should be balanced with the rate of species generation. However, as human activities have upset this balance and accelerated the rate of species extinction, the World Outline for the Conservation of Natural Resources estimates that thousands of species of plants and animals will become extinct each year, and that by the year 2000 10 20 species of plants and animals on Earth, or 501 million species of plants and animals, will disappear.

For a long time, human beings have relied on the earth.
Since the natural resources have been multiplied and developed, they are endless. However, with the development of human social activities and the transformation of the earth in the process of development, a series of environmental problems have emerged, and with the intensification of human activities, environmental problems have become more and more serious, which has affected the future development of human beings. For this reason, human beings have to start to take environmental problems seriously, and the activities to save the earth and mankind have begun.

Environmental problems faced by humanity are climate change, biodiversity loss, water depletion, soil degradation, air pollution, garbage and waste management.
1. Climate change: Climate change is one of the biggest environmental challenges facing humanity at present. Excessive greenhouse gas emissions are causing global temperatures to rise, triggering extreme weather events such as droughts, floods, and storms.
Climate change poses a threat to ecosystems, agriculture, water resources and human society.
2. Biodiversity loss: Human activities have led to the extinction of a large number of species and the loss of biodiversity. Factors such as deforestation, overfishing, land development, and pollution have had a negative impact on biodiversity, disrupting the ecological balance and reducing biodiversity on Earth.
3. Water depletion: The global water resources are facing problems such as insufficient water resources and deterioration of water quality. Factors such as excessive water exploitation, water pollution, and climate change threaten the sustainability of water for drinking and agriculture**, impacting human health and ecosystems.
4. Soil degradation in Nianfeng: Factors such as excessive land use, excessive use of fertilizers and pesticides, land degradation and land loss have led to the global problem of soil degradation. Soil degradation directly threatens agricultural production, food security and ecosystem sustainability.
5. Air pollution: Industrialization and urbanization have brought about a large number of air pollution problems. Pollutants released from activities such as vehicle exhaust, factory emissions, and coal burning lead to a decrease in air quality, causing harm to human health and the environment.
6. Garbage and waste management: With the growth of population and the improvement of consumption levels, garbage and waste management has become an increasingly serious problem. Large amounts of plastic pollution and non-degradable garbage have had a serious impact on marine ecosystems and terrestrial environments.
Here are some things we can do to mitigate environmental problems
1. Reduce greenhouse gas emissions by using clean energy, improving energy efficiency, reducing vehicle exhaust emissions, and promoting renewable energy to combat climate change. Strengthen the protection of natural ecosystems, establish nature reserves and wildlife reserves, implement plans for the protection of endangered species, and restore the biodiversity of ecosystems.
2. Formulate water resources management policies and plans, encourage the economical use of water resources, strengthen the prevention, control and treatment of water pollution, and promote sustainable use of water resources. Measures should be taken to prevent land degradation, such as rational farming, crop rotation and fallow, afforestation, etc., to promote soil conservation and sustainable agricultural production.
3. Promote clean energy and clean technology, strengthen air pollution control in industry and transportation, and standardize and strengthen air emission standards and monitoring. Promote garbage classification and waste classification system, advocate sustainable lifestyles and consumption habits, reduce the use of plastics and promote degradable materials, and strengthen waste treatment and utilization.
4. Through education and publicity activities, improve the public's awareness and awareness of environmental issues, and advocate resource-saving and environment-friendly behaviors and habits. These positive measures require the joint participation and efforts of enterprises, social organizations and individuals, and through multi-party cooperation and sustained efforts, we can contribute to protecting the environment and creating a sustainable future.

Human beings are faced with many serious environmental problems, which have a serious impact on the earth's ecosystem and human society. Here are some of the main environmental concerns:
Climate change: Climate change is currently one of the most serious environmental problems in the world. Greenhouse gas emissions from human activities, such as carbon dioxide (CO2), methane (CH4) and nitrogen oxides (NOx), are leading to rising global temperatures, rising sea levels and an increase in extreme weather events.
Biodiversity loss: Human deforestation, land reclamation, overfishing, and ecosystem destruction have led to large-scale biodiversity loss, threatening the survival of many species.
Water scarcity: Globally, water is becoming increasingly scarce and pollution is a serious problem. The demand for water not only for drinking water, but also for agriculture, industry and ecosystems is increasing.
Air pollution: Urbanization and industrialization have caused air pollution, and harmful substances in the air such as particulate matter, nitrogen oxides, and ozone pose a threat to human health.
Plastic pollution: A large amount of plastic waste enters the marine and terrestrial environment, causing harm to wild organisms and ecosystems. Microplastics also circulate in the food chain.
Soil degradation: Soil degradation includes land erosion, land pollution and land degradation, which threaten agricultural sustainability and food security globally.
Nuclear Energy and Radioactive Contamination: Nuclear accidents and nuclear waste management issues raise the risk of radioactive contamination and pose a threat to the environment and public health.
Overdevelopment and urban sprawl: Urbanization and overdevelopment have led to large-scale land alteration, which can cause damage to ecosystems and affect the quality of life of city dwellers.
Resource depletion: The overexploitation of natural resources such as oil, minerals and water resources threatens sustainable development in the future.
Collapse of core ecosystems: For example, the destruction of the ozone layer in the atmosphere and coral bleaching at Amahon Reef pose a threat to core parts of ecosystems.
These environmental problems are interlinked, and addressing them requires global collaboration and sustainable development efforts. The international community is taking steps to address these issues, such as signing the Paris Agreement to mitigate climate change, taking measures to protect biodiversity, and improving water management. Individuals and societies can also take action to reduce their negative impact on the environment and promote sustainable lifestyles.
