When I saw the military parade of China recently , I found that show lineup of huge military aircraft , but a thing deserved mentioned. It is the smog released by the flight .
Pollution has soared to hazardous levels in Beijing, reaching 20 times the limit recommended by the World Health Organisation. Smog is a significant part of pollution.Smog is mainly caused by emissions from human creations such as cars and factories, smog is hazardous chemicals and toxic matter released into the Earth’s atmosphere. While there are numerous causes of smog , industries are considered a prime source.
Industrial smog occurs when the smoke and sulfur dioxide produced from burning coal merges with fog and creates a yellowish-brown-colored haze close to ground level. Industrial smog pollutes the air around us and sulfur dioxide, its main pollutant, causes acid precipitation, which is damaging the environment.
The phenomenon is serious, who have the responsibility to control it , now it is the time to think about it .
Is that industry themselves not control it ? the answer is neutral. Some industries try to switch to low-sulfur coal would reduce sulfur dioxide emissions. Power companies have opposed the switch, citing the high cost of implementation and cost to the consumer. But on the other side for consider industries themselves, who pay for this high -techniques ? Government subside or themselves . Everyone try to use the lowest money and get the biggest profile .This is the economic market principle . But if some small industry to operate the high price of instrument to reduce the toxic
molecule ， they maybe on a deficit level. This situation is that they not wish to be happened. So when we criticize industry we also need to consider government if have already try their best to subside or control by themselves.
Like this military parade of China. Everyone know it is a time for this country to show the powerful military force , it is the embodiment of the national capacity. the colorful smog released by the flight is catch up with people’s eye. Can u image how much of smog will be create in this progress ? people just remember the gorgeous moment， forgetting the hazard of these smog treat on people’s health.
So in my opinion , there is a lot way to show a country’s ability and capability . Or maybe reduce the time of showing the flight it is a god choice .
