Our home, the Earth, is the rarest planet in-universe the to sustain life. The thing which makes it unique amongst heavenly bodies is balance in the environment. This balance is the key to sustain life for millions of years. Air is one of the most critical components of mother nature; it provides oxygen for all species, both plant and animal, to live. Air not only provides oxygen but is also essential for keeping the human body cool. The advantages of air are countless, from the cloud, weather, humidity, dust, and pollen migration to burning fire; without it, life will not continue. Air is made up of chemical components, and if pollutants added, it would become harmful for all living beings. The chapter put forward is to highlight the importance of the quality of ambient air, standards to measure, and sources of pollution. Further in the chapter, the impacts of polluted air on human health and the countries’ financial obstacles are discussed. The chapter concludes with a summary and recommendations for policymakers, NGOs, and affected people to better their lives and repair the damage caused to nature’s precious gift, the air.
