The Yellow River is under the double pressure of pollution and disconnection. 66.7% of the rivers monitored were of class Ⅳ water quality. The main pollution indexes are ammonia nitrogen, volatile phenol, permanganate index and biochemical oxygen demand.
summarize
1. Pollution status
According to the Bulletin of China's Environmental conditions, air quality in cities in China was still in a relatively heavy level of pollution in 1997, while cities in the north were heavier than those in the south (see figure 3-1). The annual average concentration of sulfur dioxide is in the range of 3 ~ 248 μ g / m ~ (-3), and the national annual average is 66 μ g / m ~ (-3). More than half of the cities in the north and the top 1/3 cities in the south have an annual average of more than 60 micrograms per meter. The annual average of north city is 72 μ g / m ~ (-3) and that of southern city is 60 μ g / m ~ (3). The pollution of sulfur dioxide in cities of southwest high sulfur coal region represented by Yibin, Guiyang and Chongqing, and the cities of Shanxi, Shandong, Hebei, Liaoning, Inner Mongolia, Henan and Shaanxi provinces with large energy consumption in the north are more serious.

The governments of all countries are supposed to formulate rules and regulations to deal with the pollution problem.
Polluted water must be purified before it was discharged.

• Plant more trees; protect the forests and all the animals
• Use of renewable materials

Air pollution is becoming a severe problem, which mainly
caused by transport action and factories production. The air pollution changes the conditions that we depend on, such as the greenhouse effect and the acid rain. It causes many diseases, too.

Everybody knows waste paper and used coke cans are thrown everywhere. You might have seen plastic bags flying in the sky and getting caught in the trees when the wind blows or maybe you have seen old cans floating in the rivers and polluting the water. Our environment is the place in which we live, but it is being ruined by us.

Environment Protection
1、Intruduce
To develop the economy, but also protect the environment, which can balance the two? It can be said that there exist the contradictions is not only a short-term problem also a long-term problem.On one hand ,human must develop the economic,but the economic development is limited by the environmental protection on the other hand when people pay more and more attention to it. We must look at the issue dialectically.
After 60 years, the stone statue of Germany has been thoroughly damaged by acid rain.
Question 3 ——Greenhouse effect
There is no doubt that global warming is very serious consequences, such as glaciers melt, sea level rise, desertification, to the ecological system and the serious impact on agricultural production.

Environmental protection is crucial for maintaining the health and well being of humans and other living organizations A clean and safe environment is necessary for basic human needs such as clean water, air, and land
The main sources of radio active contamination are nuclear power plants, nuclear weapons testing, and the proposal of radio active waste
Radioactive coordination has caused serious damage to human health and has become a global environmental issue
Avoiding buying products made from endangered animals or plants
Support companies that use sustainable practices in their operations
Participate in local wildlife protection programs or events
Environmental protection has been an ongoing concern for many disciplines The first Earth Day was cellular in 1970, sparking a wave of environmental activism and promoting governments to pass environmental laws and regulations to address pollution and resource exploration

According to the State of the Environment Bulletin of China and the report of the Ministry of Water Resources, in 1997, the seven major water systems, lakes, reservoirs, and parts of China's groundwater were polluted to varying degrees, and the proportion of river pollution was higher than that of 1996. In the dry season, the length of polluted rivers increased by 6.3 percentage points, and the periods of high water supply increased by 5.5 percentage points. Of the more than 50,000 km of rivers assessed, 42 were polluted, of which 12.2 were seriously polluted

pollution status
According to the China Environmental Status Bulletin, the noise of most cities in China was in the middle level of pollution in 1997. Among them, the impact of noise on living noise was large and expanded. Traffic noise has the strongest impact on the environment.

Definition
Environmental Protection is crucial for safeguarding the health of ecosystems, maintaining biodiversity, and ensuring sustainable development It also plays a vital role in addressing the impact of human activities on the environment and mitigating the negative sequences of climate change
Strengthening noise management, optimizing urban planning, promoting low-noise equipment, etc. are effective measures to control noise pollution.

The heat caused by infrared radiation is absorbed by "greenhouse gases" such as water vapor, carbon dioxide, ozone and methane, which slows its escape from the atmosphere.
