Conclusion Pollution Essay

While getting started can be very difficult, finishing an essay is usually quite straightforward. By the time you reach the end you will already know what the main points of the essay are, so it will be easy for you to write a summary of the essay and finish with some kind of final comment, which are the two components of a good conclusion. An example essay has been given below to help you understand both of these, and there is a checklist at the end which you can use for editing your conclusion.


In short, the concluding paragraph consists of the following two parts:


Summary

It is important, at the end of the essay, to summarise the main points. If your thesis statement is detailed enough, then your summary can just be a restatement of your thesis using different words. The summary should include all the main points of the essay, and should begin with a suitable transition signal. You should not add any new information at this point.


The following is an example of a summary for a short essay on cars (given below):


In conclusion, while the car is advantageous for its convenience, it has some important disadvantages, in particular the pollution it causes and the rise of traffic jams.


Although this summary is only one sentence long, it contains the main (controlling) ideas from all three paragraphs in the main body. It also has a clear transition signal ('In conclusion') to show that this is the end of the essay.


Final comment

Once the essay is finished and the writer has given a summary, there should be some kind of final comment about the topic. This should be related to the ideas is in the main body. Your final comment might:


Here is an example of a final comment for the essay on cars:


If countries can invest in the development of technology for green fuels, and if car owners can think of alternatives such as car sharing, then some of these problems can be lessened.


This final comment offers solutions, and is related to the ideas in the main body. One of the disadvantages in the body was pollution, so the writer suggests developing 'green fuels' to help tackle this problem. The second disadvantage was traffic congestion, and the writer again suggests a solution, 'car sharing'. By giving these suggestions related to the ideas in the main body, the writer has brought the essay to a successful close.

comment

Although they were invented almost a hundred years ago, for decades cars were only owned by the rich. Since the 60s and 70s they have become increasingly affordable, and now most families in developed nations, and a growing number in developing countries, own a car.While cars have undoubted advantages, of which their convenience is the most apparent, they have significant drawbacks, most notably pollution and traffic problems.

The most striking advantage of the car is its convenience. When travelling long distance, there may be only one choice of bus or train per day, which may be at an unsuitable time. The car, however, allows people to travel at any time they wish, and to almost any destination they choose.

Despite this advantage, cars have many significant disadvantages, the most important of which is the pollution they cause. Almost all cars run either on petrol or diesel fuel, both of which are fossil fuels. Burning these fuels causes the car to emit serious pollutants, such as carbon dioxide, carbon monoxide, and nitrous oxide. Not only are these gases harmful for health, causing respiratory disease and other illnesses, they also contribute to global warming, an increasing problem in the modern world. According to the Union of Concerned Scientists (2013), transportation in the US accounts for 30% of all carbon dioxide production in that country, with 60% of these emissions coming from cars and small trucks. In short, pollution is a major drawback of cars.

A further disadvantage is the traffic problems that they cause in many cities and towns of the world. While car ownership is increasing in almost all countries of the world, especially in developing countries, the amount of available roadway in cities is not increasing at an equal pace. This can lead to traffic congestion, in particular during the morning and evening rush hour. In some cities, this congestion can be severe, and delays of several hours can be a common occurrence. Such congestion can also affect those people who travel out of cities at the weekend. Spending hours sitting in an idle car means that this form of transport can in fact be less convenient than trains or aeroplanes or other forms of public transport.

In conclusion, while the car is advantageous for its convenience, it has some important disadvantages, in particular the pollution it causes and the rise of traffic jams. If countries can invest in the development of technology for green fuels, and if car owners can think of alternatives such as car sharing, then some of these problems can be lessened.

Essay on a Pollution Problem

Environmental pollution is one of the main threats for our planet. Pollution destroys the living environment and endangers human existence on Earth. No doubt, the economy finds many benefits in technological development. However, toxic emissions due to the work of factories, transportation, construction sites pollute the environment substantially. As the environmental pollution is a broad topic consisting of many sub-issues, there may be many approaches to building the consistent pollution essay. For instance, the pollution essay may concentrate on the various types of pollution, like sound pollution (noise pollution), water pollution, air pollution, soil pollution etc. Each paragraph of the essay will describe the separate type of the environmental pollution. Another suggestion is writing the pollution essay that highlights the consequences of pollution problems including the global warming effect, natural resources extinction, health problems of people and animals, the destruction of natural ecosystems, etc. The essay may also describe the causes of the pollution problems. Each paragraph, then, will be dedicated to one of the five main causes: industrial and technological development, transportation, agricultural activities, trading activities, and residences of people. Once you have selected the issue for the essay, you may draft the outline and move on to the analysis of the research and literature. The statistical data and approaches to pollution examination transform and improve over the time. So it is significant that you base your essay on credible and up-to-date sources. You may also look online for the essay sample on the pollution topic. However, you are encouraged to perform the research and develop your own paper first. The essay sample may be used as a practical tool and the structural example to follow.

Pollution Essay Sample

The population of our planet is increasing constantly. The population growth, unfortunately, has many adverse effects, one of which is the pollution problems. Pollution is a process of contaminating the environment in a way that it becomes unsafe to use. The contamination usually occurs through the chemical substances; however is not limited to tangible effects. The pollution can also take the form of the light, sound (noise pollution), or heat. The effects of pollution are devastative. The report of the NGO Pure Earth suggests that one of the seven deaths occurs due to pollution. Another comparison shows that pollution kills 60% more people than malaria, HIV/AIDS and tuberculosis combined. In this light, it is important to explore the various types of pollution and its effects on the environment and human beings.

One of the pivotal issues nowadays is the water pollution. The enlargement of the population means more trash and garbage. The rubbish dumps decay and the toxic substances permeate the soil going to the rivers and oceans. Moreover, tons of garbage are thrown directly into the water. There are even special islands for garbage in the oceans.

Even though the technological development offers various approaches to garbage utilization, most of the poor countries do not utilize innovative technologies. Thus, pollution becomes the leading cause of death in underdeveloped low-income countries. Nevertheless, water is contaminated not only due to regular garbage utilization. The plants, factories and mills are the key pollutants of the water. The process water from factories goes to the rivers and seas in neighborhood areas. In some rivers, the water is contaminated to the critical level and is banned from using. The fish and living environment of natural ecosystems are contaminated by dangerous chemicals that causes either the death of the entire ecosystems or hurts the consumers of the contaminated products (seafood, fish, water, salt).

Additionally, water is polluted by pesticides and fertilizations used in agriculture. The devastating effects of water pollution may be decelerated by installing the water purification mechanisms at factories and plants. These efforts should be promoted and enhanced on the governmental level. Moreover, states should develop the global programs of the environment protection as the problem is not limited to a particular territory or state. It is a universal hazard that requires combined efforts.

Another big humanity’s challenge is air pollution. Air consists of nitrogen, oxygen, water vapor and inert gases. When the typical structure of air is altered, we can observe the effects of air pollution. The primary reason of air contamination is the effect of the burning fuels. The smoke floats in the air and most people breath it in. Further, it affects the health resulting in respiratory diseases, cancers and other problems. Another type of air pollutants are dangerous gases, such as sulfur dioxide, nitrogen oxides, carbon monoxide, and chemical vapors. Those gases undergo the reactions in the higher atmosphere layers and return to the surface in the form of the dangerous chemicals (acid rains) that ruin the living environment. Moreover, carbon dioxide and sulfur dioxide create the so-called “greenhouse effect” when the radiation is absorbed while the heat is prevented from escaping. It is a natural process.

However, the high concentration of the gases makes Earth warmer and affects the natural processes on the planet. Thus, air pollution is one of the contributors to the global warming.


One of the least discussed problems is sound pollution. People tend to underestimate this problem because it is not possible to smell, see or touch it. However, noise pollution also has negative effects on the environment and people. The research shows that many illnesses are connected to noise pollution, such as hearing loss, high blood pressure, coronary heart disease and speech interference. The industrial noises also affect the lives of animals. For example, whales’ navigation system breaks down due to the sounds of ships. Besides, the industrial noise makes wild species communicate louder which requires additional efforts and decreases their life spans.

The growth of population and technological progress have imprints on the ecological stage of Earth. The extraction of natural sources, work of factories and plants, and other products of human activity result in various environmental problems. The pollution of water, air and sound have extremely negative effects on our environment. The effects of the pollution include acid rains, detrimental diseases and illnesses of people and animals, and global warming. The environmental pollution is the global problem that calls for radical actions for environment protection and rehabilitation. More than that, the problem should be resolved on a global level by the united efforts of the global community.
