Air Pollution Poignant Matters
Air pollution refers to a chemical, physical or biological alteration to the atmospheric air. It results whenever harmful gasses, smoke, or dust enters the atmosphere and in turn, hinders the survival of animals and plants as the air contains toxic substances.
The survival of human beings and animals greatly depend on the combination of gasses in the atmosphere; slight disruption of this composition can cause devastating effects on their existence. An imbalance in these atmospheric gasses is known to result in global warming, a great threat to the contemporary world. We cannot underestimate the effects air pollution has on the ozone layer which largely contributes to the existence of organisms on the planet.
Causes of Air Pollution
For the causes of air pollution to be well articulated, it is important to delve into the types of air pollutants. Air pollutants can be caused by secondary and primary sources. If a process directly results to pollution, then this forms the primary source. For instance, factories emit sulfur dioxide which is a primary source of air pollution. Reactions and interactions between primary sources form the secondary pollutant. For instance, the intermingling of primary pollutants forms smog which is a secondary pollutant.
Burning of fossil fuels
The main cause of air pollution is burning of coal, gasoline, petroleum, and other fossil fuels. These fuels are the main cause of acid rain, smog, greenhouse gas emissions, and presence of heavy metals in the air.
Fossil fuels form an important part of the society; they are used in transportation, heating, manufacturing, and even in electricity generation. This makes them an important part of the society making it difficult (but not uncontrollable) to curtail. In modern society, the use of fossil fuels can be made so that its burning becomes efficient, but this comes with a monetary cost. It is important to note that unless alternative cleaner option is found, we will have the future facing the same problems of pollution.
Increased use of motor vehicles, and emission of nitrogen
Vehicles use fuel which sometimes is not completely burnt in the engine; therefore, they release VOCs (Volatile Organic Chemicals) into the air. VOCs and nitrogen are a common source of air pollution.
Decomposition of garbage and solid wastes
Disposal sites containing biodegradable substances are known to emit methane gas into the atmosphere. Methane gas is known to be a harmful gas, it is highly flammable and a potential disaster to the ozone layer. Garbage and other household products release VOCs to the air.
Air pollution can come from natural sources such as dust, wildfires, and volcanic activity. Wildfire is known to emit VOCs and particulates into the atmosphere. Volcanic eruptions spew sulfur dioxide and volcanic ash into the atmosphere. Volcanic ash is usually dumped in the upper atmosphere, and as a result, global temperatures are lowered. However, pollution resulting from natural causes remains in the atmosphere for a short period and does not result in a permanent change as it might be the case with human activity-based pollution.
Effects of Air Pollution
1. Respiratory infections
Air pollution is the leading cause of respiratory diseases. Exposure to air pollutants can cause lung cancer and even asthma. Asthma can lead to death if not well treated, as it might cause difficulty in breathing. A prolonged exposure of pollutants can cause lung cancer.
2. Global warming
The rise in sea level, rising temperature in the world, and the melting of ice glaciers are the evidence for the global warming. Global warming is a direct effect of air pollution in the world. The only way to curb this increasingly destructive menace is to reduce air pollution.
3. Depletion of ozone layer
With the greenhouse effect which is the major contributor of the release of chlorofluorocarbon into the atmosphere has led to the depletion of ozone layer. This layer is important in shielding the earth from the destructive ultraviolet (UV) radiations.
4. Formation of acid rain
Emission of harmful gasses such as sulfur dioxide and nitrogen into the atmosphere lead to the formation of acid rain. It is quite common for rain water to have sulfuric acid due to rampant cases of air pollution in the modern society. Acid rain is a major threat to the aquatic life as well as human beings.
There are carcinogenic substances in the acid rain, and it has devastating effects to even metal which can be observed by the extent of corrosion that often results.
Air pollutants such as nitrogen oxide speed up the growth of algae on the water surface. This growth competes with aquatic life for oxygen, therefore, posing a major threat to fishing. The only way to reduce the devastating effects of air pollution will be to come up with effective ways of reducing air pollution.
Earth’s atmosphere has a self-regulating mechanism that ensures sequestration of carbon among other pollutants. The mechanism works to ensure that the ecosystem is not affected by the changes occurring in the atmosphere. However, if people continue to add more pollutants than the earth is able to remove, then the response will be increased smog, acid rain, global warming and a number of health problems.

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.
