The cause of yellow dust and fine dust is the same, but fine dust is more harmful because it is much more deadly to our bodies. The cause of fine dust can be distinguished between natural and artificial causes. 

The natural cause is the west wind. It is done by the Corioli force, which is made by rotation of the earth on its axis. Because of that, fine dust is coming to our country. 

 'Don't roasting food directly!' Every time you use a fire to cook at home, fine dust occurs. About 90 percent of non-smoking women suffer from lung cancer due to fine dust that occurs during cooking.

The artificial cause of the fine dust outbreak is a steel plant in Hebei Province, China's Hebei. Korea's car emissions are also responsible, but the main reason is its Chinese plant. 

 Here's what you can do to reduce fine dust. If there are few cars on the road, about 35 percent of the fine dust will disappear. We should avoid frying food and use boiling rather than baking. But the most important thing is to use the hood when cooking for more than 30 minutes. If you do not have a hood, you should open the window for 15 minutes instead of using the hood. Diesel and gasoline cars, smoke generated from waste and dust in construction sites can adversely affect people with allergies, skin problems and asthma. The first thing you can do to solve this problem is to walk or ride a bike.

 Korea government can do is negotiate with China to find a solution to ease fine dust. Next, many trees are planted in China and Korea. Various efforts are needed to clear the Earth from the fear of fine dust and maintain a clean environment.
