Pm 2.5 Research Paper

As we have already realized, in our industrial world, human beings’ activities have caused many damages to the environment. Air pollution is one of the biggest pollution of industrial pollution, and PM 2.5 is a very important indicator of air pollution. Specifically, PM 2.5 is the particulate matter which less than 2.5 micrometers in diameter. More vivid to show how small PM 2.5 is, a picture from United States Environmental Protection Agency shows the diameter of a PM 2.5 particulates is much less than the thickness of a human hair (Airnow, 2015). PM 2.5 pollution is very serious in many developing countries, and a typical example is China. China’s government has taken some actions to reduce the problem in recent years as well as their people. Although we should try out all the possible solutions to reduce PM 2.5 air pollution problems as soon as possible, the most important way is to change the development model, especially on energy structure. Natural processes can produce, such as volcanic ash and forest fire, PM 2.5, but according to researcher Wang, its main sources, about 90 percent of the total, are man-made emissions …show more content…
At the same time, we should reduce the coal consumption in industry, commercial, and residential utilization. The reason why it is so important is because of the fact that “China still depends on coal for more than 60% of its power, despite major investment in renewable energy sources” (BBC, 2015). Actually, I remember when I was a little child, we move to a new home, and we got the choice to choose natural gas. So I think everyone should turn to natural gas at home. Therefore, we can reduce the carbon emissions from burning coal. Another specific energy need to be in control is diesel-driven vehicles. The study from California Air Resources Committee shows 70 percent of California toxic hazardous substances in the air are from heavy diesel vehicles (Chen, G.,
