All about pollution

Pollution is the introduction of pollutants (whether chemical substances, or energy such as noise, heat, or light) into the environment to such a point that its effects become harmful to human health, other living organisms, or the environment.

The major forms of pollution are listed below along with the particular pollutants relevant to each of them:

1. Air pollution, the release of chemicals and particulates into the atmosphere. Common examples include carbon monoxide, sulfur dioxide, chlorofluorocarbons (CFCs), and nitrogen oxides produced by industry and motor vehicles. Photochemical ozone and smog are created as nitrogen oxides and hydrocarbons react to sunlight.

2. Water pollution via surface runoff, leaching to groundwater, liquid spills, wastewater discharges, eutrophication and littering.

3. Soil contamination occurs when chemicals are released by spill or underground storage tank leakage. Among the most significant soil contaminants are hydrocarbons, heavy metals, MTBE[4], herbicides, pesticides and chlorinated hydrocarbons.

4. Radioactive contamination, added in the wake of 20th century discoveries in atomic physics. (See alpha emitters and actinides in the environment.)

5. Noise pollution, which encompasses roadway noise, aircraft noise, industrial noise as well as high-intensity sonar.

6. Light pollution, includes light trespass, over-illumination and astronomical interference.

7. Visual pollution, which can refer to the presence of overhead power lines, motorway billboards, scarred landforms (as from strip mining), open storage of trash or municipal solid waste.

8. Thermal pollution, is a temperature change in natural water bodies caused by human influence, such as use of water as coolant in a power plant.



Sources and causes

Motor vehicle emissions are one of the leading causes of air pollution.China, United States, Russia, Mexico, and Japan are the world leaders in air pollution emissions; however, Canada is the number two country, ranked per capita. Principal stationary pollution sources include chemical plants, coal-fired power plants, oil refineries,[3] petrochemical plants, nuclear waste disposal activity, incinerators, large livestock farms (dairy cows, pigs, poultry, etc.), PVC factories, metals production factories, plastics factories, and other heavy industry.

Some of the more common soil contaminants are chlorinated hydrocarbons (CFH), heavy metals (such as chromium, cadmium--found in rechargeable batteries, and lead--found in lead paint, aviation fuel and still in some countries, gasoline), MTBE, zinc, arsenic and benzene. Ordinary municipal landfills are the source of many chemical substances entering the soil environment (and often groundwater), emanating from the wide variety of refuse accepted, especially substances illegally discarded there, or from pre-1970 landfills that may have been subject to little control in the U.S. or EU.

Pollution can also be the consequence of a natural disaster. For example, hurricanes often involve water contamination from sewage, and petrochemical spills from ruptured boats or automobiles. Larger scale and environmental damage is not uncommon when coastal oil rigs or refineries are involved. Some sources of pollution, such as nuclear power plants or oil tankers, can produce widespread and potentially hazardous releases when accidents occur.

In the case of noise pollution the dominant source class is the motor vehicle, producing about ninety percent of all unwanted noise worldwide.


Effects
Human health

Adverse air quality can kill many organisms including humans. Ozone pollution can cause respiratory disease, cardiovascular disease, throat inflammation, chest pain, and congestion. Water pollution causes approximately 14,000 deaths per day, mostly due to contamination of drinking water by untreated sewage in developing countries. Oil spills can cause skin irritations and rashes. Noise pollution induces hearing loss, high blood pressure, stress, and sleep disturbance.

I hate to see the phrase “destroy the environment”, especially when it occurs in sentences like “We are destroying the environment.” The phrase conjures associations with primitivism, with anti-industrialism, with counter-culture– which typically means behavior that would lead to social collapse where it implemented in full–, with a detestation with civilizations, and with a loss of very much everything we humans have achieved in the last few thousand years.

The second such a phrase gets uttered any eyeballs, not belonging to people already singing in the choir, roll backward, sighs of irritation fill the air, and visions of dirty hippies dance through the mind like grotesque clowns in a horror film. And with good reason. It is a god-damned stupid thing to say.

The only way to destroy “the environment” is to destroy every living thing on the planet. Anything short of such total destruction does not count. The environment, after all, is nothing more than a relationship between organisms and non-living things. If you’ve got one bacteria, you’ve got a relationship between it and the rock it sits upon. Hence, you’ve got an environment. Humans are not capable of such utter destruction. We have nowhere near the ability to author such devastation. We cannot– absolutely cannot– destroy the environment.

What we can do is alter it enough that things become very bad for us, and that should be our concern. That, and not the hyperbole, should be the starting point of environmental discussion. We are cabable of converting the planet into a place where we cannot survive. We are capable of producing a future where our great-grandchildren are reduced to living like chimpanzees roaming the deserts and forests chewing grass seeds. We are capable of sufficiently abusing our farmlands that they no longer produce enough to feed the species, and we start to starve en masse as in happening across parts of Africa now and as has happened to local population of humans in the past, on Easter Island for example. We can poison our food and water enough to reverse the happy trend toward longer average lifespans. These should be our concerns.

And these concerns should not be peppered with counter-productive hyperbole. Yes, I understand that “destroy the environment” has more punch than “make ourselves uncomfortable”. Likewise, “Bush is a Nazi” has more shock value than “The Bush administration favors legislation frightenly like that favored by totalitarian regimes”. In either case, though, opting to argue via shock-value at the expense of accuracy means one immediately loses one’s audience. And what is the point of arguing in the absence of an audience?

I also understand that most environmentalists really mean more or less just what I’ve said– that we can make the world a wretched place for ourselves. That really is the translation of “destroy the environment”. That also is beside the point. There are some forms of argumentation, some forms of debate or rhetorical techniques that are simply counter-productive. I am tired of hearing such things from the mouths of the good guys. Nonetheless…

Tree -- our earth "life"

As we know, many pollution like water pollution and air pollution has been occurred because of the unlimited deforesting... Should this be done , guys?Let us think carefully...
