Agricultural pollution refers to the contaminants present in the environment as a result of agricultural practices. Most effects of agricultural pollution are felt in water environments and are caused by runoff from farms and barnyards such as ammonia, pesticides, fertilizers, oil toxins, and animal waste that make their way into bodies of water. Agricultural pollution also negatively affects the quality of air. Chemicals and byproducts from the agricultural industry are quite harmful to the natural environment and can pose a problem for humans as well. As the world’s population continues to grow at a significant rate the demand for intense agriculture will remain high, and so combating agricultural pollution will be increasingly difficult. With this in mind, several alternatives to industrial agriculture, with its polluting tendencies, have been explored and are being utilized today.

Pesticides used to kill insects that feed on crops can cause much damage to the environment if used inappropriately. Excessive pesticides remain in the soil after sprayings and are washed away by rain that forces them to be absorbed into groundwater. Avoiding pesticide contamination is a tricky process only feasible through careful containment practices. The same problem exists with the use of fertilizers. Excrements produced by cattle and other barnyard animals also cause pollution. The methane released from cow flatulence is also a type of greenhouse gas making it partly responsible for global warming. Emissions from the use of fossil fuels by tractors and other farm equipment used in agriculture also contribute to air pollution. Fires, which are not uncommon on farms, can be very detrimental to the environment if fertilizer or waste products are being burnt. The problem of agricultural pollution is not simply felt in regions in farming regions. Contaminates in rivers can be carried all the way to the ocean and polluted air can be blown to other areas with denser populations.

Agricultural pollution poses numerous human health problems. Chemicals that make their way into groundwater can eventually end up in water sources that are used for drinking. Blue baby syndrome, a disease that causes death in infants, is often caused by contaminated water. Pesticides released into the air and emissions from farm equipment cause difficulty breathing and a host of respiratory problems. Fertilizers, manure, waste, and ammonia that are present in water release nitrogen that reduces the amount of oxygen present resulting in the death of fish and other marine animals.

While industrial agriculture is the most efficient way to produce large quantities of food, the pollution associated with it raises many environmental and health concerns. In light of this, there has been a shift to organic farming which uses more natural ways to raise crops and livestock and avoids the use of harmful chemicals. The use of alternative crops that require less fertilizer because they are adapted to the environment in which they are grown also help to reduce agricultural pollution. However, the demand for cheaper and higher quantities of food as world population steadily rises will make changes in farming methods less likely and more difficult.


Just the other day, I experienced the nauseating sensation of driving down a pass into the air pollution in Los Angeles. We need clean air to be healthy, but these air pollution facts make me ill.


Air Pollution In California


There are many different types of pollution that affect our environment. The Earth’s waters are affected by pollutants such as chemicals and medical waste, and the land itself is also polluted with garbage and even more types of chemicals. Some of the worst pollution that affects us daily, however, is air pollution. Here are some air pollution thoughts that should make you hack, cough and start wearing a filter mask.


Air pollution is a general term that is used to describe any chemical, biological or other matter that causes changes in the atmosphere. A good example is the pollution caused by large cities, which is also known as smog. Smog is the accumulation of all the dirt and chemical pollutants produced by a city or area, and it can be detrimental to our lungs, other animals, plants and even the ozone layer high above us.


The particularly nasty thing about air pollution is the silent, unseen impact it has on us. Whereas we can see and taste water pollution, air pollution is much less obvious. It is, however, still deadly. For instance, everyone knows smoking is bad for you and will ruin your lungs. Yet, not a single person either seems to know or care that among air pollution facts, one of the ugliest is as follows. If you drive in rush hour traffic in Los Angeles with your window rolled down, the harm to your lungs per hour is equal to smoking two PACKS of cigarettes. TWO PACKS!


Holes in the ozone layer, which is a layer in the upper atmosphere, allow more harmful UVB (ultraviolet B) light to reach us from the sun. This light can cause skin cancer as well as sun burns and lesser ailments. There are other causes for the holes in this layer besides just smog, and these include carbon dioxide released from burning fossil fuels and even the exhaling of farm animals. While we would consider most of the harm done to the atmosphere to be caused by chemicals, air pollution facts tell us that even animals have a hand in creating air pollution.


So, what can we do to stop air pollution? While there is no way to completely get rid of pollutants that harm our air quality and ozone layer, we can help to eliminate man made causes of atmospheric distress. Cutting down on the use of fossil fuels, using non-chemical based cleaners, and generally thinking “green” can all help to reduce the amount of air pollution we produce. A fundamental solution is to get off of fossil fuels for our cars and the hybrid vehicles are a good start. If the mythical hydrogen vehicle ever comes to be, the reduction of air pollution in major cities will be astounding.


While there is no real way to fix the damage we have already done to the atmosphere, people can definitely stop more problems from occurring. In your everyday life, try to produce less air pollution by taking simple steps to use less chemicals and fossil fuels. We’ve got a long way to make the world a less polluted place, but every little step towards a “greener” Earth will help us all breathe a little easier.

You will learn about “Air Pollution” in this video. Cutting of trees is one of the major reasons of air pollution. Air also gets polluted due to the smoke released by many factories and industries. Burning of wood and fossil fuels is another reason of air pollution. Also, vehicles such as cars, buses, trucks etc. give out a lot of smoke that pollutes the air. Due to air pollution, human beings suffer from a number of diseases like asthma, bronchitis, cancer, skin diseases etc.

Air pollution also affects the growth of plants and causes damage to our beautiful historical monuments. As responsible citizens, it is necessary to take up some preventive measures to reduce air pollution and its effects. We must plant more trees, avoid bursting firecrackers, make more use of public transport and ensure that regular servicing of our vehicles is done. Lastly, factories and power plants should also be set up far from residential areas, which will help in reducing air pollution.

Water Industry Network HC : In recent years, under the guidance of scientific concept of development, China’s water pollution prevention and control has been gradually strengthened, and in advancing the construction of key pollution control projects, more attention watershed pollution control management system and operational mechanism of the improved focus on administrative, economic, legal and the integrated use of engineering techniques and coordination. Beginning in 2007, the country began to pollution reduction, “double down” trend, focusing on water pollution prevention and control have made new progress, institutional mechanisms, the role of water pollution treatment in progressive highlights. As China’s industrialization and urbanization phase of rapid development, water pollution prevention goals and changing mode of economic development, construction, resource conservation and Environment Friendly society, there is considerable demand gap, especially in some long-standing institutional barriers and mechanisms and the issues that must be resolved to accelerate the establishment and the socialist market economic system to adapt to the water pollution control systems and mechanisms and tasks challenge of great significance.

1, the current institutional mechanisms for water pollution prevention and control of several major problems exist

Present, there are many water pollution control issues, policies and regulations are not perfect, insufficient capital investment, lack of public participation, technical support system is weak and so on, but the most fundamental problem is the management system is not fully rationalized , the operating mechanism is not enough coordination, especially in the following areas:

(A) The department coordinated the problem is not solved, the effective functioning of a unified comprehensive mechanism has been formed

Water pollution prevention and control is a typical multi-sectoral issues, the existing institutional framework for water pollution management, there Environmental protection , Water Resources, Development and Reform Commission, the construction of a number of departments involved, the main environmental protection departments. Multisectoral collaboration is not the source of the problem itself, the current problem is mainly the role of environmental protection is not given full play, department conflict, in particular environmental protection departments and water departments in the areas of lack of water pollution prevention is more effective collaboration has become water pollution control administration is facing one of the main system. Water and environmental conflicts in the watershed management departments have concentrated expression, involving planning, water quality monitoring, institutions, water allocation and total pollutant control, management and supervision of transboundary pollution, water pollution and other aspects of dispute mediation. In the river basin management, the obvious contradiction between the dual management system, such as the seven river basin management institutions are set up Water Resources Protection Bureau, Ministry of Water Resources and the State to accept nominal the dual leadership of the Ministry of Environmental Protection, Ministry of Water Resources sent a fact that the nature of institutions This restricts the basin agency’s role in water pollution control. From the part of the watershed management practices, the existing sectoral coordination difficult than regional coordination difficult. Huai River pollution control practice ten years shows that the two departments of environmental protection and water co-led leadership group name only, is the “Decade of the Huaihe River pollution control,” the important system ineffective one of the reasons.

(B) of the central and local powers and responsibilities of the pollution control division and the regulatory mechanisms are not perfect

In the central and local management on the relationship between water pollution control, management at different levels in China, namely, as a unit of administrative division, the regional environmental authorities bear the main responsibility for water pollution control, and superior environmental protection department of the local Environmental Protection Bureau Only the right guidance. As the local environmental protection departments of local government functions, causing it to easily become a tool for local interests, whether the data monitoring, pollution control, or approval of the construction project must be local, while the higher-level environmental protection departments of supervision can not exceed the local Government authority, such as state environmental authorities were ordered to close down the business but for the local government for asylum. SEPA’s monitoring of local environmental management there is no power to break local protectionism. GDP at current to the core of performance evaluation under the baton of economic development as local governments often give priority on the development and promulgation of the State Council’s environmental policy is difficult to put in place. The past two years, the State Environmental Protection Administration has increased the local regulatory efforts, have launched a “regional restrictions” and “river basins” and strong administrative punishment. But in the long term, need to establish trans-boundary river basin water quality control responsibility and total pollutant discharge accountability to the central place of the standard incentive clear, open, fair and local water pollution control is expected to provide a stable and long-term incentives.

Air pollution is the emission of substances in the atmosphere that interferes with the amenities of live. Air pollution could also be defined as any process that alters the standard component of the atmosphere by quantity or quality.

Air pollutants may be classified as follows

* Aerosol is a term used to describe dusts of small particle size, smoke and some mists whose presence can be really revealed by its scattering of visible radiation. Aerosols cover a wide range of gaseous disperse systems consisting of particles of low vapor pressure which settle slowly under gravity.

* Smokes are formed by combustion, destructive distillation or volatilization

* Dusts are solid particles dispersed into the atmosphere as a result of mechanical disintegration of a body of matter.

* Mist consists of droplet as a result of condensation of vapor in the air. When there are many particles in the droplet, it is called fog. When there is droplet with particle and dust at the same time it is called haze and if there is fog as well as poisonous gases, it is referred as smog.

* Acid rain, this occurs when the rain water pH falls below 5. It is usually as a result of presence of CO2 in the rainwater. Gaseous emission is a very important aspect of air pollution especially the green house gases (CO2, CFC, and NO2) that it emits in the atmosphere.

The effect of air pollution could be categorized as follows.

Earth warm and climate change; this is as a result of green house gases in the atmosphere. When the solar radiation strikes the earth surface, some of these gases trap the heat of the sun and thereby giving rise in the increase of temperature of the environment. The effect of this rise in temperature is shifts in temperature and rainfall. Sea level will rise as a result of thermal expansion of the ocean. Some area will be subjected to drought. Another effect of these gases is the depletion of the ozone layer.

Air pollution affects the health of the body ranging from eye irritation to lung diseases.
Acid rain is one of the very dangerous effects of air pollution. Its environmental effects range from acidification of lakes and streams resulting in reduction of fish population. It could also lead to the damage of vegetation, structure and equipment.

The cause of air pollution are as follows; domestic and industrial activities, Transportation sector and thermal power stations.

Air pollution control achievement depends on a well knowledge of the source of the pollution.

Pollution in the transportation sector can be curbed by

*taxation aimed at penalizing inefficiency in fuel consumption.

* Developing more efficient fuel combustion systems.

* Installation of systems to monitor the exhaust of automobile.

* encouraging mass transit

Pollution by industries should be controlled as follows

*Polluting industries may be regulated to emit pollutant only on a favorable wind movement and direction.

*Erection of tall stacks which usually also have high velocities in them so that the pollutants are sent in the high part of the atmosphere, where they will be diluted and made harmless.

*Use of fossil fuel should be reduced and resorting to much more environmental friendly source of energy should be encouraged.

*Industries should use scrubber to trap most of the pollutant that they emit.

Developing countries should endeavor to have consistent power supply so as to discourage the use of domestic generators. However, the flexible strategy of controlling air pollution remains the use of taxes and price mechanism

In spite of your painstaking research, finding a location which is free from environmental pollution is quite impossible. We can say pollution on the earth is omnipresent and it is hard to escape from the effects of pollution unless you take precautionary measures to mitigate the effects of these pollutants. South Carolina is one among the states of US that is suffering greatly from the ill effects of pollution.

Environmental pollution is the major challenge on the table of the world. Our greed to technological advancement has sworn the pollution with many powers. It has now gained the control over earth, environment, and life of the inhabitants including humans. South Carolina also occupies place among the states that is majorly affected by the pollution.

Apart from the poultry, cattle breeding and tourism some industries also contribute to the economy of the state. The industrial sector of the state includes textile goods, chemical products, paper products, machinery, automobiles and automotive products.

The industries which are part of states economy is throwing a major challenge to the other sub sectors of the economy. Tourism industry and poultry cattle breeding are facing a great decline in the income generated in the state. The reason is only one; the toxic substance emitted from the industries is affecting the natural quality of the environment and is affecting the tourism industry in turn. Improper disposal of waste by these industries is causing a great change in the environmental balance and is affecting the food and contaminating the water in the state. The cattle and poultry industry being fed with the contaminated food is unable to yield the expected output

The irresponsible acts of residents of the state also contribute to the environmental pollution of the state in addition to the trash disposed by the industries. The residents of the state stand silent as spectators of the drastic environmental change that is taking place in the state and blame the industries as the reason, I agree that industrial waste generated in the state is the major contributor of the pollution in the state, but the trash generated by the projects handled by the individuals adds to it.

Careless deeds of residents and industries of the state are making the pollution rule the land. It is of no surprise if you soon happen to see the government of the state frames a law to enforce green living mandatory where you have to sacrifice your comfort zones. All your hard work to invent technologically advanced projects will go in wane. They will be soon out of your current life style. Though it sounds scary, it becomes inevitable for the government of the state to enforce the law to sustain the living atmosphere in the state if the same situation continues to persist.

The best way to escape all these horrifying situations is to find the ways to dispose the trash in effective manner. Disposing the trash in effective manner will reduce the effects of pollution on the environment making it sustainable for comfortable living. None other than dumpster rental company South Carolina will help in recycling the trash in environmental friendly manner. These dumpster rental companies will keep you away from all the trash disposal tasks and get your trash disposed in effectively at affordable cost. Dumpster rental companies of South Carolina are the best tools to face the challenges thrown by the environmental pollution in South Carolina.
