Vehicle pollution is one of the main causes of air pollution in cities. The burning of petrol and diesel releases harmful gases such as carbon monoxide and nitrogen oxides, which damage the environment and human health. It leads to breathing problems, global warming, and climate change. The increasing number of vehicles and traffic jams make the problem worse. To reduce vehicle pollution, we should use public transport, bicycles, carpooling, and switch to cleaner fuels or electric vehicles. Planting trees and regular vehicle maintenance also play an important role in controlling pollution.
