Asbestos is a very harmful substance usually used as construstion materials. I believe you all know about this. But still, many architects use Asbestos because of their unique qualities flexibility and insulation. What if Asbestos is used in academies where children study all day long, or schools? What will happen if the children get exposed ti high percentage of Asbestos contained buildings, they might have serious cancers such as lung cancer, asbestosis pulmonum, and laryngeal cancer. As there are benefits, there are harmful side effects as well.

Because of these dangerous side effects, many countries started to ban the use of Asbestos for construction and everything. But still, like some academies in Seoul, people use Asbestos ilegally. About two years ago, some environmental organizations have researched how much the academies in Seoul contain Asbestos. The result was bad. Most of the academies in Nowongu, Seoul contained Asbestos about 2~10% which is way over the limitaion that the goverment has set in 2009(0.1%). Well, the academies that were discovered to contain a lot of Asbestos in 2013, didn't get better but got even worse. Most of the academies 25 out of 30 had cracks or damage of the part that contained Asbestos, and they were not fixed.

Bu this research, we could see that even though there are laws about Asbestos, not to use construction materials that contain Asbestos over 0.1%, many people are not observing the law in the construction site. Asbestos is the material that the World Health Organization (WHO) selected as the class one carcinogens.

In order to stop using Asbestos, or to prevent getting cancers by Asbestos, first, we should use other materials that can substitute Asbestos like wollastonite and sepiolite. Second, we should be careful when we demolish the building because they are hard that they still lay behind even though the whole building is demolished.

We should not only care about the topics like global warming but the environment that we live these days. Then the small changes will lead to a big barrier to the climate change.
