   Today, I tell about the resource and reason that made of smog, where the smog comes from; and what people need to do in order to deal with it. The audience can learn more information by knowing these three questions and the answers of them.

What is air pollution

  • Smog is noxious gas and minute particles of solid and liquid matter(particulates) in concentrations that endanger health
  • What is haze? Sometimes when people turn off the light, there is PM2.5 among the air. They are the particle  diameter less than 2.5 microns and they can refract a lot of visible light, leaving us with a low visibility. In other words, this is a war with unseen enemy. When the value of PM2.5 increased, mortality rate is the rise of the population; the research institutions have done this trend calculations; “Measurement results is that the number of premature deaths is five thousands of people because of the air pollution in China.”

the Causes of Air pollution

 Smog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution—some visible, some invisible—that contribute to global warming. Generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment is considered air pollution.

 Carbon dioxide, a greenhouse gas, is the main pollutant that is warming Earth. Though living things emit carbon dioxide when they breathe, carbon dioxide is widely considered to be a pollutant when associated with cars, planes, power plants, and other human activities that involve the burning of fossil fuels such as gasoline and natural gas.

personal response

   When I came home last winter, I could smell the smoke. At first, I were confused that why I could smell the smoke in the airport. I asked my parents and my friends whether they could smell it or not, they took a deep breath, and said no. At that moment, I knew they had already used to it, and they could not realize how dangerous it was. That smell made us feel headache for many days, and then we could not feel it anymore.  We only stay at home for 10 days, and we started to cough badly. We even could not stop dirt getting into our throat and made us cough worse because we could not stop breathing. I started to be afraid, because I felt how strong the enemy was. When I came back to America, I really felt that I got rid of air. But, I still worry about our family and friends. How could they deal with this huge and horrible monster?

 Under the serious haze, we have at least one thing we can do is to protect yourself and your lovers. Thousands of children are born; The rivers, the sky, and the earth should belong to them, we do not have the right to consume only know I do not know restraint, we have no right to complain,we have a responsibility to show them the energy of the world that is clean and beautiful.
