What has the country included in the smog?

On January 4, the National Disaster Reduction Office and the Ministry of Civil Affairs reported natural disasters in 2013, including haze weather for the first time. According to the report, in 2013, the central and eastern regions of my country suffered from severe haze, with frequent and frequent haze weather. Except for August, the number of haze days in every month is higher than the same period in history. Among them, the haze weather is particularly serious from January to March and September to December.

The National Disaster Reduction Office classified haze weather as a natural disaster, which caused widespread discussion. Many netizens believe that smog is a man-made disaster rather than a natural disaster. In fact, according to the definition of natural disasters:

"Natural disasters" are abnormal phenomena that occur in nature on which humans depend. The harm caused by natural disasters to human society is often shocking. Among them are sudden disasters such as earthquakes, volcanic eruptions, mudslides, tsunamis, typhoons, and floods; there are also gradual disasters such as land subsidence, land desertification, drought, and coastline changes that will gradually appear over a long period of time; and Environmental disasters caused by human activities such as changes in the ozone layer, water pollution, soil erosion, and acid rain.

It can be seen that haze days, like floods, acid rain, and sandstorms, should be a natural disaster.

But the moment the government includes smog as a natural disaster, does it mean that we will all be ravaged by smog in the next N years? By highlighting the word "natural", doesn't it seem like there is a certain avoidance of the important and the trivial?
