        Unexpected Function of Yellow Dust for Environment

  

 

Many people know that yellow dust has only negative effect on human lives. However, yellow dust is helpful for our environment for 3 reasons.  First of all, yellow dust helps prevent global warming. According to the NOAA, yellow dust cools down the Earth. Aerosol in yellow dust diffuses sunlight, and carbon in the aerosol absorbs sunlight. This lessens sunlight that reaches the ground directly. To be specific, according to the news report of IPCC, aerosol has a -2 degree effect on global temperature. It means that it cools down the Earth 2 degree. Secondly, yellow dust neutralizes acid rain, soil, and lake. Because yellow dust contains alkaline substances, it helps neutralize the acid in rain. Moreover, there is 12% of lime in yellow dust; lime and magnesium oxide neutralize soil and lake. Finally, yellow dust is really helpful to plant growth. Magnesium and potassium are very important minerals for plant. As yellow dust supplies these minerals, it helps growth of plants. For example, because rock bed of Korea is consisting of granite, soil is lack of these minerals. In this case, yellow dust is utilized as mineral suppliers. Moreover, according to the Weizmann Institute of Science, Saharan dust supplies minerals on Amazon forest. It shows that yellow dust plays an important role as supplier which gives these minerals. For these reasons, yellow dust is helpful to the environment. Of course, it has some negative effects on human. However, it makes the Earth healthier unexpectedly.
