What Is Pollution?

"A pollutant is a waste material that pollutes air, water or soil. Three factors determine the severity of a pollutant: its chemical nature, the concentration and the persistence." Wikipedia.

It is the black smoke coming from exhaust It is the garbage laying along the side of the road It is the slime and sludge floating on the waters of the planet It is waste from industry It is oil spills It is what humans have contributed to their planet.

The constant wiping out of wildlife, and trees that actually help this planet breathe. Why would people want to annihilate things that help them breathe?

What is Pollution?

It's people not taking care of the planet It's people not doing their small share of cleaning up It's people not using caution with chemicals and exhaust It's people not leaving the forests alone It's people that don't turn down the noise

Pollution accumulates from gases, and all the detrimental things that soil the earth and fill the air with toxins. Toxins are contaminants that cause harm to the environment. Pollution has been here since time began. It has grown with society and flourished, in some cases better than society. When you think about back in time, blacksmiths, coal and wood smoke.

Throughout wars, over the centuries, the hazards and destruction have created pollution. In December of 1952 in London, Englawnd, an event named "The Great Smog" lasted less than a week but darkened most of the city. This writer remembers this well having lived in it. It was like being trapped in a smoke filled room for days, there was no way out. In some places, you couldn't see your hand the length of your arm away. Pollutants created from anticyclone and windless conditions, combined with the cold weather caused airborne pollutants to form a layer of smog over the city. This was caused mostly from the burning of coal. What is pollution? It is a murderer. This smog was responsible for contaminating over 100,000 people. Total fatalities resulting from this Smog were over 12,000.

Attention to pollution has been in the US since the 1950's. Congress passed specific acts to clean up the environment, but it would appear from the present state of this country, that these acts definitely were not adhered to.

There is not much hope for the ecosystem considering the dumping in the Hudson River, long-term dioxin contaminants that started in 1947 have accelerated to the testing of nuclear weapons and dispersing of lethal radioactive contaminants throughout the earth's air. The constant addition of more and more, garbage and gases.

For the last time What is pollution? Pollution is aircraft gas and noise, industrial gases, herbicides, pesticides, and radioactivity. Streets filled with Neon lights, and highways covered with billboards. Landfills and garbage dumps. Exhausts and smoke. Millions of tons of pollutants are released into the environment on a daily basis. The world will become like the 1952 Smog episode in London, England unless something serious is done.

One writer is glad she is older, but worries about the future of the younger generations and we need to take the time to consider that. Words won't change the world, but "with a little help from a friend" this earth can at least get a reprieve, giving it a little time to breathe.

Lesser-Known Effects of Pollution

Pollution is the introduction of elements into any environment that upset the equilibrium of the environment and cause instability, discord or harm.

Pollution can take many different forms: air pollution, water pollution, soil contamination, radioactive contamination, noise, light, visual, and thermal pollution are a few of the well-known forms of pollution.

The main effects of pollution have been well documented and debated. Higher incidences of respiratory and cardiovascular ailments caused by air pollutants have become ubiquitous and alarming. A very high number of deaths in developing countries are due to the consumption of contaminated water. Hearing loss, high blood pressure, sleep disturbances, cancer, and birth defects are some other effects of different forms of pollution.
Over and above these "usual" effects of pollution, some lesser-known effects have also started emerging. For example, a recent study links air pollution to low IQ in children. Researchers have established that mothers who breathe in air with higher pollution levels during their pregnancy are likely to bear children with lower IQs. The implication of this study seems to be that while toxins pollute the environment as a whole, they also pollute our bodies and make us mentally slower. Chemicals, preservatives, and additives that go into packaged food, and pesticides that go into natural food, all qualify as pollutants.

Another study claims that air pollution appears to cause genetic changes that make infants more prone to asthma in later life. The researchers believe that air pollution induces changes in gene expression without changing the structure of the gene itself. While there has long been a link between pollution and the higher incidence of asthma, the effect on a gene is definite cause for concern

Air Pollution and Global Warming

Global warming has scared the entire world in last few years. Well, it has done all good, at least people now know what they have done till now and how harmful it would be for our earth if we continue doing like this. Our Earth has abundant natural resources and till now we have been using it indiscriminately without realizing that one day all these may just vanish.

Ever since the human civilization has taken place the man kind has been playing with the environment. The human activities and technological advancement has lead to serious consequences.

Global warming is a resultant effect of green house gases. Greenhouse gases contain carbon dioxide, nitrous oxide, methane, sulfur dioxide all these gases are trapped in the atmosphere causing a rise in the earth's temperature. Air pollution is directly proportional to global warming. Industrialization, automobile fumes, burning of fossil fuels all these are responsible for air pollution, and it has been depleting the ozone layer in pockets of southern hemisphere over Australia. Depletion of ozone rays allows the harmful ultraviolet rays to reach Earth's surface and therefore, many cases of skin cancer and other diseases have been reported from these parts of the world.

Air pollution is known to cause asthma and other forms of respiratory ailments. In many countries, air pollution has reached such dangerous levels that people are forced to use masks to avoid respiratory ailments. The flora and fauna of the Earth are reducing at an alarming rate, and if it continues like this, it would destroy everything very soon.
