Most Polluted Countries 2019

Pollution not only hurts our planet, but it also has negative effects on humans. Air pollution caused by the burning of fossil fuels in factories, cars, airplanes, and for electricity can cause serious health problems. Even the use of aerosol products and pesticides can affect the air that we breathe. Humans may face health problems such as wheezing, breathing problems, worsening of asthma, or even birth defects from air pollution.

Our land and water can also become polluted. This can be caused by littering or even the dumping of chemicals by industries. This pollution can affect our wildlife and our plants and trees, and it can even contaminate our drinking water. In other words, pollution is dangerous for us all.

As we see the effects of pollution on our planet and ourselves, more countries are looking to green alternatives to prevent further damage to the earth. Solar and wind energy, eco-friendly building materials, and non-toxic products are being used to help preserve our planet. While some nations are becoming more “green” and eco-friendly, others still have a long way to go.

In 2017, data from the World Health Organization was used to determine the most polluted nations on the planet. This data evaluated the concentration of PM 2.5 particles in the air. PM 2.5 are particles that are produced through combustion, such as driving a car or operating a power plant.

A total of 92 nations were evaluated to determine which had the highest number of PM 2.5 – in other words, which nations were the most polluted. According to this data, Pakistan has the most polluted urban areas with an average PM 2.5 concentration of 115.7. Falling behind Pakistan was Qatar with a PM 2.5 average of 92.4. In third place was Afghanistan with a PM 2.5 average of 86. According to this study, other nations with high levels of pollution include:
