A considerable number of individuals believe that the main source of pollution in cities is car while other think the main causes are the industries. Although the cars creates noise and air pollution, I believe the water pollutants and release of chlorofluorocarbon by the industries are more responsible for environmental degradation.
To begin with, the quality of air is affected by the gas released by the cars. The car releases harmful gases that is mixed with the air which reduces the air quality hampering the health of peoples. Moreover, noise pollution is created by the vehicle in the traffic congestion. This is because, people gets frustrated by waiting for long time, and start blowing horn which deters the peace. For instance, the junction near to my house is always very noisy, because of the people driving the car who kept blowing the horns. However, electric vehicles are now being popular which has not any deterimental effects on environment thus, I think it is not the major reason of environmental contamination.
On the other hand, the emission of chlorofluorocarbon can be seen from the industrial sites. The chlorofluorocarbon is produced by the factories that negatively affect the ozone layer which restrict the harmful rays of the Sun. Likewise, water contamination is occurred by the factories. They throw all the wastes in the water sources as, it is easy and convinent ,but dangerous for the animal living inside it. For example, Nepal has witnessed decline in fishes in previous years due to waste thrown in the rivers.
In conclusion, the cars are responsible for creating noise and air pollutants in the industries for the ozone layer depletion and water pollution. In my opinion, the biggest reason for environmental degradation is industries because it do not have viable solutions.
