Air Pollution

The excess accumulation of pollutants or undesirable alterations in the environment and its resources such as air, water, and land can be referred to as pollution. Pollution affects the components of the environment. Pollution is considered a global issue as it is showing harmful effects worldwide. Metropolitan cities are more impacted by pollution than countryside or villages.
