Writing an Expository Essay About Pollution
One of the main causes of climate change is pollution. Pollution is the introduction of harmful substances or products into the environment. There are four known types of pollution: air pollution, water pollution ,land pollution and noise pollution.
Air pollution is mainly due to human activity. The air of populated cities is contaminated by car fumes and factory smoke coming from industrial areas.Consequently, the rate of respiratory diseases like asthma is very high. In addition to this, when it rains, the high percentage of chemicals forms acid rain. This results in contamination of animals and plants.
Water pollution affects water-streams, rivers, seas and oceans. Rivers and seas are contaminated by domestic sewage and chemical effluent especially if the used waters are not treated. The consequences are visible on the environment. Desperate sight of rivers and sea shores that used to be famous for their natural beauty: corpses of fish and all kinds of garbage are washed on river banks and seashores.
Land pollution is occasioned by our throw-away society. As number of inhabitants is increasing, the quantities of rubbish to dispose of cause a serious threat to our environment. Moreover, the expansion of industries everywhere is responsible for the destruction and the extinction of natural species of plants and animals .The chemical waste of these factories affects the natural growth of species of plants and so poisons the sources of food that man and animals depend on.
We generally perceive noise pollution in urban areas. The roar of cars , the screaming of planes and the intense noise made by human activity in certain populated cities make life of the citizen unbearable. As a consequence, many inhabitants of crowded cities suffer from ear problems and psychosomatic diseases.
To conclude , all kinds of pollution are real dangers not only to our direct environment but to our health as well. Therefore, world governments must find the best ways to reduce their consequences and make them less harmful. The use of renewable energy sources and the recycling of used products are the only solutions if we want to preserve life on Earth for the coming generations.
