Two Major Air Pollutant Crisis
As the weather becomes colder, more and more family will use coal for warming themselves. Specially in north of China. Always in winter, haze will come.
A recent assessment on air pollution controls has advised northern regions to put stricter guidelines on bulk coal consumption, especially in the heating seasons, while also arguing a cap on coal consumption could further reduce greenhouse gas emissions.
As we all know, bulk coal consumption has been proven to be more polluting than coal consumption in industries, which generate more airborne pollutants than the level discharged from companies.
For example, bulk coal consumption, including those used in households for heating in winter, was more than 36 million tons annually, accounting for less than 10 percent of the total consumption in the Beijing-Tianjin-Hebei region.
As we all know, in north of China, there are more factories and autos. It can produce more emissions than other regions. Besides, half of the total airborne pollutants emitted was generated from bulk coal consumption and another was generated from increasing number of autos. That is why haze always like to visit these regions.
"The effective curbs in bulk coal consumption could help the governments control the smog, which has been proved true in the process of easing the severe air pollution last year, and it will remain a major effort that the governments take in the coming winter," Chai Fahe, deputy head of the China Research Academy of Environmental Sciences, told the conference where the assessment report was released. But how can we solve another problem?
On January in Beijing last year, the haze weather is more than 24 days and more than doubled over the same period. However, not just China, but haze weather affected on around world. It is strongly associated with increasing number of car.
According to investigation, when car is working, spark plug ignites fuel and combustion produces power. This process will produce a large number of nitrogen dioxide, it will increase acidic material in atmosphere and cause acid rain.
Simply set the standard of vehicle exhaust emission is not enough, it is of great urgent that raising the conscious of environmental ethics. The standard which set by human may still do harm for other creatures. Not only for our human, but also for other creatures, we must protect our environment, save energy, and reduce emissions.
