Effects of Air Pollution on Human Environment |

Levels of air pollution vary widely across different regions and countries. In 2019, the World Health Organization (WHO) estimated that 9 out of 10 people worldwide breathe air containing high levels of pollutants.The most common air pollutants include particulate matter (PM), nitrogen oxides (NOx), sulfur oxides (SOx), ozone (O3), and carbon monoxide (CO). These pollutants can come from a variety of sources, including transportation, industry, agriculture, and natural sources like wildfires and dust storms. According to the WHO, air pollution is responsible for an estimated 7 million premature deaths each year, making it one of the leading causes of death globally. Fine particulate matter (PM2.5) is one of the most harmful air pollutants, as it can penetrate deep into the lungs and bloodstream, causing respiratory and cardiovascular problems. In 2019, the global average concentration of PM2.5 was 25 micrograms per cubic meter, but levels varied widely across different regions. Air pollution can also have a significant economic impact, due to healthcare costs, lost productivity, and damage to crops and ecosystems. The World Bank estimates that air pollution costs the global economy $5 trillion per year in welfare losses. Governments and international organizations are taking steps to address air pollution through policies and regulations aimed at reducing emissions from transportation, industry, and other sources. However, progress has been slow in many areas, and air pollution remains a significant public health and environmental challenge. |

Hello Dafford! This is your mentor Yewon.
Before I start the comment, I apologize for the late comment.
You have written an outstanding report about air pollution, with impressive beginning showing statistics from WHO. The statistics you proposed in your report are very surprising! As air pollution effects human health so badly, as you mentioned in your report, it is important for humans to protect the earth from air pollution!
Thank you for your great work!

Hello Dafford! This is your mentor James.
I can't believe that 7 million young lives are being lost due to air pollutants! It is true that NOx, SOx, and Ozone pollutants result in respiratory issues such as asthma and even heart diseases as well, but I didn't know the actual number of the casualties. PM is also a major issue in East Asia from since decades ago. Every spring, the atmosphere of Korea is intolerable due to fine dust from the industrial sectors.
Thank you for your meaningful report! Keep up the good work!
