The majority of air pollution today is caused by A) Combustion (Fuel Burning).
Here's why:
1. Combustion of fossil fuels, such as gasoline in vehicles, coal in power plants, and wood in stoves, releases pollutants into the air.
2. These pollutants include carbon monoxide, sulfur dioxide, nitrogen oxides, and particulate matter, which contribute to smog, acid rain, and respiratory issues.
3. Industrial processes and transportation are major sources of combustion-related air pollution.
4. Human activities that rely on burning fossil fuels for energy production are significant contributors to the air pollution problem.
In contrast, options B, C, and D are not the primary causes of air pollution. Ozone layer depletion is related to certain chemicals like chlorofluorocarbons (CFCs) but does not directly cause air pollution. Thermal inversions can worsen air pollution by trapping pollutants close to the ground, but they are not the main source of pollution. Volcanic eruptions release ash and gases into the atmosphere, but their contribution to overall air pollution is relatively small compared to human activities like combustion.
