According to ground breaking research it doesn’t mean that the increase in cars in the city will cause all the air to be polluted, but we can consider it as a key factor.
First of all, companies in developing countries should stop competing with each other, because where there is competition, car production systemstically harms the air. To solve this problem, governments and individuals must take action. Most vevicles run on fossil fuels such as petrol and diesel, which release harmful gases into the atmosphere. In addition, factories and power plants produce large amount of smoke and toxic emissions.
Secondly, as a goes into great detail, it is better to produce more electric cars. And we need to reduce the movement of old cars through the city. For example, we should make it so that only cars manufactured in 2010 can enter the city, because cars after that years are electric at environmentally friendly cars.
In conclusion, urban air pollution is a growing concern caused by transportation, industry, and urbanization. Nevertheless, with proper measures such as sustainable transport, clean energy, and environmental awareness, it is possible to create cleaner and healthier cities.
