Step-by-step explanation:
The release of smoke from a bus can have negative effects on human health. This is because the smoke contains pollutants that can be harmful when inhaled. The pollutants in the smoke can irritate the respiratory system, leading to symptoms such as difficulty breathing and coughing.
Prolonged exposure to the smoke can also increase the risk of respiratory infections and decrease lung function. In addition, the chemicals in the smoke, such as those found in second-hand tobacco smoke, have been linked to the development of cancer and other conditions.
