Air pollution ?

Air pollution refers to the presence of harmful substances in the air that can have negative effects on human health, the environment, and the overall quality of air. These substances, known as pollutants, can be either natural or man-made and can come from various sources such as industrial emissions, vehicle exhaust, burning of fossil fuels, agricultural activities, and wildfires.

Common air pollutants include particulate matter (PM), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), and volatile organic compounds (VOCs). These pollutants can have detrimental effects on respiratory health, causing or exacerbating conditions such as asthma, bronchitis, and other respiratory diseases. Long-term exposure to air pollution has also been linked to cardiovascular diseases, lung cancer, and premature death.

Air pollution not only affects human health but also has adverse impacts on the environment. It can contribute to the formation of smog, acid rain, and depletion of the ozone layer. Additionally, air pollution can harm ecosystems, leading to the decline of plant and animal species, and disrupt the balance of ecosystems.

Efforts to reduce air pollution include implementing stricter emission standards for industries and vehicles, promoting the use of clean and renewable energy sources, improving public transportation systems, and raising awareness about the importance of reducing individual carbon footprints.
