Sometimes the sky we look up is unusually beautiful.
It is hard to afford to look up the sky in busy everyday life. But now the sky to look up has disappeared. And when you go out to the provinces, it's become a habit to see the sky and breathe in clean air.
Looking at the sky makes one to think of something. When a person think about something big or before a person make a decision either in a film or in a reality, they always look far. But our reality is trapped in a close distant monitor.
Like this, we have lost our sky both physically and mentally.
The story of the lost sky we talk about is not just due to romanticism that seeks to see the beautiful sky. It is a story that touches much closely. Because this is a problem that is directly related to our health.
There are two major reasons for the disappearance of the star in the sky. One is due to the light of the city, and the other is due to air pollution. Between them, polluted air is now a very big problem.
It is a story about the fine dust (PM10) and ultrafine dust (PM2.5) that have become a hot topic in recent years. They were designated by the World Health Organization as a first-generation carcinogen on October 17, 2013, which falls within categories such as alcohol and tobacco. In fact, if the inclusion of the fact that it is almost impossible to avoid without affecting the daily life, the severity will be even more serious.
This fine dust problem has two main contexts. One is the fine dust from China talking in the media and the domestic fine dust that the Korean government talks about.
In fact, it was not just the problem of today that there was no fine dust in the past. It was always the problem, but we did not have a solid knowledge of it. But this should not make the present problem any smaller. If we compare the present and the past when humans did not know the health effects of tobacco, we can feel it.
The situation of domestic fine dust greatly depends on the wind direction. This can be found in the [analysis of the factors influencing ultra fine dust (PM2.5) in Korea] by Park Soon Ae and Shin Hyun Jae. "The ultrafine dust concentration and westerly wind direction ratio in Shandong province have a + effect on the concentration of ultrafine dust in Korea. This is because, as pointed out in many previous studies, the Chinese factor …(omit)… has a significant effect on the increase of ultrafine dust concentration in Korea.” In addition, domestic factors include coal power generation and diesel consumption, and they seem to have little direct influence on the concentration of ultrafine dust in Korea.
However, there should be no skepticism that there is nothing that Korea can do, inducing Korean companies not to be alarmed simply because fine dust problem is heavily influenced by China.
As an alternative to thermal power generation, some people suggests to use nuclear power generation and there is even a move toward nuclear power generation as an environmentally friendly energy source. But you should not fall into this dangerous thought. The reason is that human have no way to completely solve a nuclear waste problem.
The main cause of the fine dust is the thermal power plant. Rather than simply depriving our daily routine with a mask, we need a radical solution. Of course, the spread of eco-friendly energy (wind, geothermal, solar power, hydropower, etc.) is considered necessary. Our lifestyle is also important. Yes. Perhaps the closest and easiest thing for us is to save energy and reduce waste, and to take a position against both international and domestic companies that give negative impacts on the environment. And remember every purchase is a vote.
As Lester R. Brown says, it is time for us to recall that the present world we enjoy is not an asset inherited from our ancestors, but borrowed from the future.
The air is beautiful last few days. These everyday things come with great joy.
