What are some of the major environmental problems facing out society? / Lee Hayoung


 High nitrogen dioxide emissions are a long-standing environmental problem. Nitrogen dioxide is toxic and highly oxidized, and is made up of one of the pollutants in the atmosphere. Inhalation is a gas in which more than a majority of animals die at concentrations above 100 ppm due to respiratory tract or lung infringement. It also changes the characteristics of clouds, blocks sunlight and absorbs solar radiation. All of these factors affect the Earth's climate and temperature. This can lead to regional warming, and vice versa, cooling the climate.
 Due to the various economic activities of humans, these gases are generated and we are experiencing various climate change. However, it is not fortunate, but most human activities have been suspended due to the corona virus, leading to another natural change with about 30% of nitrogen dioxide drastically reduced.
