Coal burning factories and increased automobile usage had caused

a significant increase in air pollution. The burning of coal in factories releases large amounts of greenhouse gases and particulate matter into the atmosphere. These pollutants can have detrimental effects on human health, such as respiratory problems and increased risk of heart disease.

Increased automobile usage also contributes to air pollution through the emission of pollutants from vehicle exhausts. Vehicles release carbon monoxide, nitrogen oxides, sulfur dioxide, and other harmful substances into the air. These pollutants can contribute to smog formation and negatively impact air quality.

The combination of coal burning factories and increased automobile usage has led to the deterioration of air quality in many areas. This has resulted in an increase in respiratory illnesses, such as asthma, and other health issues related to poor air quality.

Additionally, air pollution from these sources contributes to climate change by increasing the levels of greenhouse gases in the atmosphere. Greenhouse gases trap heat and contribute to the warming of the planet, leading to various environmental impacts like rising temperatures, melting glaciers, and changes in weather patterns.

There have been efforts to reduce the impact of coal burning factories and automobile emissions on air pollution. These include the implementation of stricter emission standards for vehicles, the promotion of renewable energy sources to replace coal, and the development of technologies that minimize the carbon footprint of factories. However, more actions and policies are needed to address the issue comprehensively and effectively.
