 Using global satellite maps, NASA scientists examined air pollution trends over the last decade in various regions and 195 cities on the earth. In this research, nitrogen dioxide hotspots are used as an indicator of general air quality. Because nitrogen dioxide can quickly transform into ground-level ozone, a major respiratory pollutant in urban smog. According to HASA research findings, the United States, Europe and Japan have improved air quality thanks to emission control regulations, while China, India and the Middle East, with their fast-growing economies and expanding industry, have seen more air pollution.

 We can understand what factors cause this outcome. The difference between the developed nations and the developing areas is what the priority is. In the developed countries, consumer needs are security, safety, health, sustainable environment, and others, while people in the developing regions are still interested in pursuit of material affluence and convenience.

 However, even though nitrogen dioxide level is decreasing, in Syria, the civil war has reduced economic activities.

Above map is the trend of the Middle East which shows the change in nitrogen dioxide concentrations from 2005 to 2014. Blue indicated an observed decrease in nitrogen dioxide.

 Fortunately or unfortunately, new, high-resolution global satellite maps of air quality indicators tell us human brutality, stupidity and cruelty of war as well as the environmental problems objectively. Conversely, I think that human beings are great to develop that science technology like the satellite. Whether we make the best of the warning or not is also up to us. We must keep it firmly in our mind.

 By the way, using the map of satellite, who can see truly about the title of this news?
