Air pollution effect on environment
Giving a heavy and major threat to the nation’s health along with the economy of the country, air pollution is a silent killer that no one takes seriously, but is a major concern and needs to be addressed. Having the world’s most toxic/worst air pollution, we are home to the 22 of the world’s 30 most polluted cities, killing almost a million people each year and affecting everyone from humans to animals to crops to cities to forest to aquatic life. Air pollution is a big contributor to global warming and climate change. In fact, the abundance of carbon dioxide (Co2) in the air is one of the primary causes of the greenhouse effect. Usually, the presence of greenhouse gases should be beneficial for the planet because they absorb the infra-red radiation produced by the surface of the earth, but the excessive concentration of these gases in the atmosphere is the cause of the changes in climate condition in recent years. In 2019, air pollution was the fourth leading risk factor for early deaths world wide. Toxic substances present in the environment produced by human activities are the main reason behind the air quality getting worse day by day. Air pollution has a major impact on the process of plant evolution by preventing photosynthesis in many cases along with having serious consequences for the purification of the air that we breathe.
Not just this, air pollution also contributes to the formation of acid rain, atmospheric precipitations in the form of rain, frost, snow or fog as well, which are released at the time of combustion of fossil fuels and transformed by contact with water steam in the atmosphere. Our continual exposure to air pollutants is responsible for the decline in human health as compared to before human health conditions. Air pollution is indeed a significant risk factor for human health conditions, causing severe health hazards like allergies, respiratory and cardiovascular diseases as well as damaging lung.
