Read material one and material two and talk about what phenomena are reflected. Please analyze the reasons for this phenomenon.

1, material 1 shows that the country is paying more and more attention to low-carbon development of energy conservation and emission reduction.

Material 2 shows that urban pollution is seriously exceeding the standard.

2. Reason: (1) Industry: Industry is an important source of air pollution. There are many kinds of pollutants discharged into the atmosphere by industry, including smoke, sulfur oxides, nitrogen oxides, organic compounds, halides, carbon compounds and so on. Some are smoke and some are gas.

(2) Living stoves and heating boilers: A large number of living stoves and heating boilers in cities need to consume a lot of coal, and coal will release a lot of harmful substances such as dust, sulfur dioxide and carbon monoxide to pollute the atmosphere during combustion. Especially when heating in winter, it often makes the polluted area filled with smoke and makes people cough, which is also a pollution source that cannot be ignored.

(3) Transportation: Cars, trains, planes and ships are the main means of transportation at present, and the waste gas produced by burning coal or oil is also an important pollutant. Especially, the number of cars in cities is large and concentrated, and the pollutants discharged can directly hit people's respiratory organs, causing serious air pollution in cities and becoming one of the main air pollution sources in big cities. The exhaust gas emitted by automobiles mainly includes carbon monoxide, sulfur dioxide, nitrogen oxides and hydrocarbons, and the first three substances are very harmful. (Your writing is simple)

Countermeasures: (1) Attach great importance to environmental legislation and law enforcement. China has formed an environmental protection legal system based on the Constitution and taking the environmental protection law as the main body. This provides a legal basis for protecting and managing the environment and implementing the basic national policy of protecting the environment, but the law enforcement needs to be strengthened.

(2) Strictly enforce the law and protect the environment according to law. We should actively study and publicize environmental protection knowledge and relevant laws and regulations, strictly observe the law and discipline ourselves, and do nothing that pollutes and destroys the environment. We should use legal means to oppose and stop environmental pollution and protect the environment according to law.

(3) "It is everyone's responsibility to protect the environment". The government should intensify the special rectification of environmental pollution according to law; Teenagers should also start from now on, fulfill their legal obligations of environmental protection, not pollute the environment, and actively participate in public welfare activities to protect the environment.
