Modern society is not complete without transport. Now both freight and public vehicles are used, which are supplied with various types of energy to ensure movement. Currently, the following vehicles are used in different parts of the world:
- automobile (buses, cars, minibuses);
- railway (metro, trains, electric trains);
- water (boats, boats, container ships, tankers, ferries, cruise ships);
- air (planes, helicopters);
- electric transport (trams, trolleybuses).
Despite the fact that transport allows you to accelerate the time of all movements of people not only on the surface of the earth, but also through air and water, various vehicles have an impact on the environment.
Each type of transport pollutes the environment, but a significant advantage - 85% of the pollution is carried out by automobile transport, which emits exhaust gases. Cars, buses and other vehicles of this kind lead to various problems:
Maritime transport most pollutes the hydrosphere, as dirty ballast water and water washed by swimming vessels enter the reservoirs. The power plants of ships pollute the air with various gases. If tankers transport petroleum products, there is a risk of oil pollution of the water.
Air transport primarily pollutes the atmosphere. Their source is aircraft engine gases. Thanks to the work of air transport, carbon dioxide and nitrogen oxides, water vapor and sulfur oxides, carbon oxides and particulate matter get into the air.
Electric transport contributes to environmental pollution through electromagnetic radiation, noise and vibration. During its maintenance, various harmful substances enter the biosphere.
Thus, when operating a variety of vehicles, environmental pollution occurs. Harmful substances pollute water, soil, but most of all pollutants enter the atmosphere. These are carbon monoxide, oxides, heavy compounds and vaporous substances. As a result of this, not only the greenhouse effect occurs, but acid rain also falls, the number of diseases is becoming more frequent, and the state of human health is deteriorating.
