1, air pollution caused by fireworks. The smoke produced by setting off fireworks is the "flavor of the year". Setting off fireworks will produce gases such as sulfur dioxide, nitric oxide and nitrogen dioxide, and it is an invisible "killer". When the smoke is filled, these gases do some harm to all parts of our human body and stimulate our eyes.

2. Noise pollution. The constant explosion of fireworks and firecrackers on New Year's Eve often makes it difficult for people to sleep on New Year's Eve. The noise in the area where firecrackers are set off is as high as 135 decibels, which far exceeds the hearing range and tolerance limit of people. At night, the noise acceptable to people should not exceed 45 decibels, which is equivalent to the sound of frogs. Moreover, high-intensity noise is very harmful to patients with cardiovascular and cerebrovascular diseases. There are cases of severe hearing loss, explosive deafness and hearing impairment caused by setting off firecrackers in China almost every year.

3. It is a manifestation of the lack of social morality. One hundred people listen to one person, and the family is not at ease, which is very bad for children and the elderly. Make people form a bad habit of thinking only about themselves and not caring about others, thus their sense of public morality is weak.

4. Waste resources and pollute the environment. Exploding valuable resources, such as paper (trees) and chemical raw materials (including the pollution caused by the production of these raw materials), makes the streets full of wolves, and people will develop irresponsible habits after releasing them.
