1, acid rain is the enemy of everything on earth.

2. The earth doesn't want to be jealous anymore!

3. It is everyone's responsibility to prevent acid rain!

4, dark sky, don't let sadness turn into tears!

5. Isn't acid rain a complaint from the sky?

6. Prevent acid rain for the benefit of future generations.

Ways to reduce acid rain:

1, saving energy and reducing pollution. Formulate a set of basic policies for energy conservation, strengthen energy management and formulate a set of technical policies for energy conservation. Limitation: Eliminate existing industrial boilers and kilns with high coal consumption, low thermal efficiency and heavy pollution.

2. Adjust the civil fuel structure to reduce energy pollution. Gradually realize the gasification of civil fuels and gradually realize urban central heating.

3. Improve coal utilization technology. The high-sulfur coal with sulfur content greater than 45% is changed into low-sulfur coal with sulfur content less than 2.7%.

4. Strengthen the control of automobile exhaust. Formulate exhaust emission standards for various vehicles, limit vehicle speed, improve engine combination and install anti-pollution devices. Implement the system of regular elimination of motor vehicles as soon as possible.

Hazards of acid rain:

Acid rain refers to atmospheric precipitation such as rain, freezing rain, snow, hail and dew with pH less than 5.6. A large number of environmental monitoring data show that the cloud water over most parts of the earth is becoming sour due to the increase of acidic substances in the atmosphere. If it is not controlled, the area of acid rain area will continue to expand and the harm to human beings will increase day by day.

It has been proved that sulfur dioxide and nitrogen dioxide in the atmosphere are the main substances that form acid rain. Among the acid rain components determined in the United States, sulfuric acid accounts for 60%, nitric acid accounts for 32%, hydrochloric acid accounts for 6%, and the rest are carbonic acid and a small amount of organic acids. Sulfur dioxide and nitrogen dioxide in the atmosphere mainly come from the combustion of coal and oil, and they form seed acids dissolved in rainwater under the action of oxidants in the air.

According to statistics, about 654.38 billion tons of sulfur dioxide and 50 million tons of nitrogen dioxide are discharged into the atmosphere every year, so acid rain is mainly caused by human production activities and life.
