A Sample of an Air Pollution Essay
Undoubtedly, many researchers consider air pollution to be one of the most burning issues nowadays. Scientists identify the most common reasons that contribute to air pollution, among which one may find human activity, technological advances, industrialization, and global warming.
Usually, clean air is made of certain gasses. However, when other gasses are emitted into the atmosphere, the air becomes polluted. Consequently, the contamination of air negatively affects the ozone layer, which, in its turn, provokes drastic changes in the natural habitat.
People also contribute to the contamination of air. Cigarette smoke emits carbon monoxide, which significantly pollutes air as well. However, the most harmful gas is carbon dioxide, a chemical compound that is revealed in the atmosphere from volcanoes or burning of coal. Whenever carbon dioxide reaches the atmosphere, the ozone layer is exposed to its drastic negative effects.
Nevertheless, air pollution is interconnected with another burning issue – global warming. Since the temperatures in numerous countries get higher, glaciers and icebergs begin to melt, which lead to the increase of the sea level. The result is obvious – many species lose their natural habitat and cannot find an appropriate shelter with the same conditions.
One should not underestimate the effects of acid rains on people and the environment. When acid rain occurs, water drops contain dangerous compounds that fall on the ground. Thus, human beings, as well as flora and fauna are exposed to severe risks.
The most obvious consequence of air pollution is the spread of numerous diseases among people, such as tracheitis, bronchitis, and even cancer. Researchers state that millions of people suffer from these illnesses annually.
It is evident that air pollution contributes much to the destruction of the ozone layer and spread of different diseases. It is high time to take some decisive measures to preserve the environment and its flora and fauna.
