There are several types of pollution, and while they may come from different sources and have different consequences, understanding the basics about pollution can help environmentally conscious individuals minimize their contribution to these dangers. In total, there are nine recognized sources of pollution in the modern world. These sources of pollution don't simply have a negative impact on the natural world, but they can have a measurable effect on the health of human beings as well.
Air pollution is defined as any contamination of the atmosphere that disturbs the natural composition and chemistry of the air. This can be in the form of particulate matter such as dust or excessive gases like carbon dioxide or other vapors that cannot be effectively removed through natural cycles, such as the carbon cycle or the nitrogen cycle.
Air pollution comes from a wide variety of sources. Some of the most excessive sources include:
- Vehicle or manufacturing exhaust
- Forest fires, volcanic eruptions, dry soil erosion, and other natural sources
- Building construction or demolition
Depending on the concentration of air pollutants, several effects can be noticed. Smog increases, higher rain acidity, crop depletion from inadequate oxygen, and higher rates of asthma. Many scientists believe that global warming is also related to increased air pollution.
Water pollution involves any contaminated water, whether from chemical, particulate, or bacterial matter that degrades the water's quality and purity. Water pollution can occur in oceans, rivers, lakes, and underground reservoirs, and as different water sources flow together through the water cycle the pollution can spread.
Causes of water pollution include:
- Increased sediment from soil erosion
- Improper waste disposal and littering
- Leaching of soil pollution into water supplies
- Organic material decay in water supplies
The effects of water pollution include decreasing the quantity of drinkable water available, lowering water supplies for crop irrigation, and impacting fish and wildlife populations that require water of a certain purity for survival.
Soil, or land pollution, is contamination of the soil that prevents natural growth and balance in the land whether it is used for cultivation, habitation, or a wildlife preserve. Some soil pollution, such as the creation of landfills, is deliberate, while much more is accidental and can have widespread effects.
Soil pollution sources include:
- Hazardous waste and sewage spills
- Non-sustainable farming practices, such as the heavy use of inorganic pesticides
- Strip mining, deforestation, and other destructive practices
- Household dumping and littering
Soil contamination can lead to poor growth and reduced crop yields, loss of wildlife habitat, water and visual pollution, soil erosion, and desertification.
Noise pollution refers to undesirable levels of noises caused by human activity that disrupt the standard of living in the affected area. Noise pollution can come from:
- Manufacturing plants
- Construction or demolition
Some noise pollution may be temporary while other sources are more permanent. Effects may include hearing loss, wildlife disturbances, and a general degradation of lifestyle.
Radioactive pollution is rare but extremely detrimental, and even deadly, when it occurs. Because of its intensity and the difficulty of reversing damage, there are strict government regulations to control radioactive pollution.
Sources of radioactive contamination include:
- Nuclear power plant accidents or leakage
- Improper nuclear waste disposal
- Uranium mining operations
Radiation pollution can cause birth defects, cancer, sterilization, and other health problems for human and wildlife populations. It can also sterilize the soil and contribute to water and air pollution.
Thermal pollution is excess heat that creates undesirable effects over long periods of time. The earth has a natural thermal cycle, but excessive temperature increases can be considered a rare type of pollution with long term effects. Many types of thermal pollution are confined to areas near their source, but multiple sources can have wider impacts over a greater geographic area.
Thermal pollution may be caused by:
- Power plants
- Urban sprawl
- Air pollution particulates that trap heat
- Loss of temperature moderating water supplies
As temperatures increase, mild climatic changes may be observed, and wildlife populations may be unable to recover from swift changes.
Light pollution is the over illumination of an area that is considered obtrusive. Sources include:
- Large cities
- Billboards and advertising
- Nighttime sporting events and other nighttime entertainment
Light pollution makes it impossible to see stars, therefore interfering with astronomical observation and personal enjoyment. If it is near residential areas, light pollution can also degrade the quality of life for residents.
Visual pollution - eyesores - can be caused by other pollution or just by undesirable, unattractive views. It may lower the quality of life in certain areas, or could impact property values and personal enjoyment.
Sources of visual pollution include:
- Power lines
- Construction areas
- Billboards and advertising
- Neglected areas or objects such as polluted vacant fields or abandoned buildings
While visual pollution has few immediate health or environmental effects, what's causing the eyesore can have detrimental affects.
Personal pollution is the contamination of one's body and lifestyle with detrimental actions. This may include:
- Excessive smoking, drinking or drug abuse
- Emotional or physical abuse
- Poor living conditions and habits
- Poor personal attitudes
In some cases, personal pollution may be inflicted by caregivers, while in other cases it is caused by voluntary actions. Taking positive steps in your life can help eliminate this and other sources of pollution so you can lead a more productive, satisfying life.
Pollution Types Are Connected
All types of pollution are interconnected. For example, light pollution requires energy to be made, which means the electric plant needs to burn more fossil fuels to supply the electricity. Those fossil fuels contribute to air pollution, which returns to the earth as acid rain and increases water pollution. The cycle of pollution can go on indefinitely, but once you understand the different pollution types, how they are created, and the effects they can have, you can make personal lifestyle changes to combat poor conditions for yourself and others around you.

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.
