An air quality map released by the World Health organization shows that almost everyone in the world is breathing polluted air. Around 92% of the world is now currently breathing in air that does not meet air quality standards set by the World Health Organization.

This is a very alarming fact because air pollution can have detrimental consequences on the human body; air pollution particles can get in human bodies when we breathe and can be found in the lungs, heart, and even the brain. In fact, more than 2 million premature deaths were linked to air pollution in 2015. These are horrifying numbers and will only get worse as global urban pollution rises.

Pollution is made up particulate matter, also known as PM, and are tiny clusters of and dust and pollen, visible to the human eye. They include other pollutants such as nitrate, sulfate, and black carbon; all of these are dangerous when inhaled in large quantities. It increases inflammation, oxidative damage to cell membrane lipids and our DNA. Additionally, studies show that it might have an impact on cognitive, metabolic, and immune functioning. They can aggravate or cause asthma, cardiovascular diseases, and respiratory diseases.

Areas of high PM levels can be found in major cities around the world, notably, in Paris, London, New York, and Los Angeles. Regions in the Western Pacific, Southeast Asia, and Saharan countries also have a high amount of air pollution. Obviously, areas with large public transit, factories, and industry show an extremely alarming amount of air pollution. The World Health Organization strongly advises that government regulations and enforcement are essential to lowering our PM levels. The world needs to rely on a cleaner and more renewable source of energy if we want to prevent more casualties from a lack of clean air.
