The Most Dangerous Road In the World

 La Paz - The World's Most Dangerous Road
Between the barren altiplano capital of La Paz and the verdant Yungas coca capital of Coroico lies one of the most dramatic and deadly roads in the world. Built by the blood and sweat of prisoners during the war with Paraguay in 1932, the “Death Road” is still the only route that connects Northern Bolivia with the capital. This absurdly narrow road is heavily traversed by buses, minivans, trucks, tankers, taxis, private vehicles, and mountain bikes. Mountain bikes! That’s right; the world’s deadliest road is open for tourism, only in Bolivia. Despite the fact that (or because of it) there is an average of one accident every two weeks and 200 fatalities annually, tourists are just bursting go down this road and then proudly wear their “I Survived” t-shirts. Tourist companies are only too ready to oblige. There are no less than 25 companies in La Paz to provide for your adrenaline fix hundreds of mountains bikes (just think how many dodgy brake pads are out there?). Ironically enough, my father emailed us just after we booked our trip informing us that there is a deadly road near La Paz and we should “avoid it like the plague” (how does he learn about these places before we get there?). So when the next day arrived, Cara and I met our small group of six (including guide and driver), suited up in garishly ugly orange pants and jackets, grabbed our gloves and helmets, and piled into a mini-van whose paint job proudly advertised what it was that the crazy gringos inside were about to do. We climbed up out of La Paz (already at 3800m) to a ridiculous 4700m. Below the outstretched arms of a large Jesus statue we chased down bread and jam with coffee. We adjusted our seats, tested the breaks, kicked the tires, and prepared ourselves psychologically for the ride of our lives. After a very brief instruction from Wince, our guide, the time came. With Jesus at our backs at three miles high we slowly rolled down the paved road that fell into the valley below. It didn’t take long. After seconds we were rocketing down the mountain at horrifying speeds. One tiny rock in the road would have been disastrous leading to “hair, teeth, and eyes” on the road (to once again quote my father). With our knuckles completely white, our noses numbed, and ears deafened, we passed trucks going down. We had two brief respites in the first two hours when we had to walk our bikes through two DEA check points (can our government keep its stinking nose out of anything?) There was an 8km section of uphill cycling, which ended up being a show of machismo by the guys more than anything. At 3600m (12000ft) this was a killer and it took me nearly 10 minutes of hyperventilating before I could control my breathing. Shortly after, the two lanes of pavement ended. The new road, that was supposed to be finished two years ago (I figure local officials must put on the finishing touches to their new houses with the international aid to build the road before focusing their attention on the road itself) goes up and the narrow rock and earth road (that kills people) continues down into the lush cloud forest.
Other Dangerous Roads In The World


YungasRoad
9 May 2004. The following article appeared first in the Sunday Independent, Sports Active supplement.
Yungas road mountain bike accident accident - rope crew lifting the casualty
Helping hands: the rescue team work frantically to save the life of a mountain biker who has fallen into the valley below Bolivia's Yungas Road. Since work on the road finished in 1935, as many as 200 people have died annual in accidents. Despite this, the road continues to draw large numbers of enthusiasts on walking and biking trips.
Bolivia's Yungas Road is officially the most hazardous on earth. Local people pray before using it and the nearest hospital is a two-hour drive away. But none of this deters foreign tourists from biking over its bumps at 40mph. And, as Michael Liebreich discovered, cheap thrills in risky environments can come at a price.
You can't walk 100 yards down the main street of any travellers' town on this lonely planet without being offered a selection of adrenalin-enhanced adventures. A river nearby? We provide inner tubes. Mountains? Touch your own personal void. Now I'm all for getting the heart racing on holiday but my opinion of what is an appropriate adventure activity and of what constitutes an acceptable riskchanged dramatically one day last summer.
It started with a flyer in the lobby of our hotel in La Paz: "Mountain-bike the most dangerous road in the world," it said. "A spectacular 38-mile ride, descending more than 11,800ft from the Andean mountains into the Amazonian jungle". To a group of climbers with a spare day before our departure from Bolivia, it sounded the perfect way to end our trip.

World's Most Expensive Houses

The Updown court- most expensive house in the world

The Updown Court complex, housed at Windlesham, England is not only known as one of the most important residential complexes in and around London, it is also the worlds most expensive house floating in the market. Launched in the market for sale at 70,000,000 pounds ($110,684,000 US dollars) it is also the largest residential construction in the United Kingdom since the 19th century.

The history of the Updown Court has not been as vibrant as its present and near past. Originally, it was built in an area spanning 58 acres of land, with an in-built lake and woodlands. The initial building was completed in 1924 and was supposed to house the prince of Egypt- Sam Gaye.  Unfortunately, the whole area was burnt and devastated in an ugly fire during 1987. It was Leslie Allen Vercoe, a designer by profession, who then went on to buy this burnt-out reminiscent of the original property. It was purchased by him for roughly $40 million at that time.

After purchasing the property, Vercoe had teamed up with John Scholz, and architect from Arizona and an Irish bank to reconstruct, re-design and fund the mansion. The bank has supplied funds to the tune of $60 million since then to Vercoe, which he has invested on beautifying the property further. From Guatemalan marble in the bathrooms to a dual natured staircase and trey slated rooftops, the house contains the best in modern contemporary designing. All these things have contributed a great deal in making Updown Court the worlds most expensive house. Up to this day the house remains unsold.
For now it seems that no one can afford this magnificent house. The house has been opened to the public very few times and there are a lot things that make the worlds most expensive house worth the money. The estate has more than 100 rooms, out of which each of the 24 bedrooms has their own marble laden ultra-luxurious bathrooms. You enter the house through a drive-way, which alone is said to be priced at $3 million.
The Updown Court has everything that is necessary for making the worlds most expensive house stand up to the expectations of its inhabitants. It has two bowling alleys, a tennis court which is floodlit, and five swimming pools with varying difficulty levels and a squash court also. The worlds most expensive house is also one of the safest, as it has an emergency panic room, designed to provide protection in the even of a terrorist or military attack. The underground garage with granite flooring can house up to eight limousines at a time.
The Updown Court also has a cinema hall, with a seating capacity of up to 50 people. Apart from these features and facilities, the worlds most expensive house has expensive terraces, covered with Italian flooring of at least 30 known kinds, a wine cellar and two separate penthouses, occupying a full section of the house. The main living area is said to be on the first floor, which contains eight tastefully appointed bedroom suits with lush terraces and great view.

The worlds most expensive house is not that cheap to maintain either. According to reports, the estimated cost of upkeep of this property amounts to 250,000 pounds per month. The Updown Court has had a lot of coverage from various magazines around the world, with the Business week giving it the title of being a “billionaire’s statement house”.  Apart from all the hype and the publicity, relatively very less is known about the actual inhabitants of the house and their lifestyles. One can only infer that being the next-door neighbor of Elton John and the Duchess of York is not everybody’s cup of tea and therefore, the worlds most expensive house is bound to be a lavish extravaganza, nonetheless.

Other Expensive Houses Of The World
Anguilla
Trump Most Expensive house Mansion Florida
Villa Leopolda
It is the same worlds most expensive house on the French Riviera but a different buyer. Whilst last month, there was a news that Russian billionaire Roman Abarmovich inked a deal with the La Leopolda, priciest house ever by spilling over $500 million. But the rumor is lately proven to be false and here is a revision version. Another Russian billionaire became the fortunate buyer for the princely villa located on the French Mediterranean coast after shelling out �390 million. The Telegraph reports that a secrecy Russian billionaire who is not Abramovich gave over all his fortune for Villa Leopolda, a Belle �poque mansion in Villefrance on the C�te d’Azur.
The house is owned by Lily Safra, widow of Edmond Safra, a Lebanese banker who was killed by an arsonist’s fire in Monaco in 2003. Within few years, the news came that the house was bought by Bill Gates and became the worlds most prized estate. The estate is spread over two guest houses across 20 acres of grounds with countless olive, cypress and lemon trees taken care by 50 gardeners.

How To Insure Your Life trough World Wide

Life Insurance Basics – It's Not As Bad As You Think

Life insurance is a contract between an insurer (a life  insurance company) and a policy owner to insure the life  of an individual. In many cases, the individual being  insured is also the policy owner.
The life insurance policy pays a death benefit to a  named beneficiary (which is stipulated in the contract by  the policy owner) upon the death of the insured.
Life insurance was originally designed as a way to help pay for burial costs. However, today, life insurance is used for a wide variety of purposes both personal and  business including insuring the life of business owners  (to keep the business operating after the owner's death),  key employees, supplemental retirement income, defined benefit plans, to protect an individual's pension benefits  (i.e. "pension max"), and traditional income replacement  (in the event of the death of either spouse).
Today's life insurance contracts also include suicide  provisions to prevent insurance companies from having to pay claims on policies where the insured has committed  suicide within the first two years of the policy. Insurance companies also require that there be an "insurable  interest" between the policy owner and the insured (to help prevent a conflict of interest between the owner of a policy and the person being insured).
While not technically accurate, financial advisers and insurance agents tend to divide insurance contracts into the two different "types": term insurance (temporary) and cash value insurance  (permanent).
Term insurance is temporary or "pure" insurance. The  policy owner pays a defined amount of money for a specific  amount of death benefit. When payments stop, the insurance  ends. Term policies tend to be very inexpensive when the  insured is very young, and are guaranteed to get more  expensive as the insured becomes older. Due to expected mortality rates, term policies also tend to have a very low payout ratio which is estimated to be between 1% – 3%.
Cash value policies are often defined by insurance  companies as "a death benefit with a savings component".  This "savings component" is actually a cash reserve that is designed to grow in value until the reserve equals the death benefit. In the beginning, the policy owner pays for the death benefit and an  additional amount of money is set aside in a cash value  account which is part of the insurance contract. With each premium payment, the costs associated with mortality and other expenses are either  guaranteed to decrease every year – in the case of whole life – or is expected to decrease every year – in the case of universal life (if the level death benefit option is elected).
A unique feature of cash value policies is that the cash value is allowed to grow income tax deferred. The  money can then be withdrawn or a loan can be taken against  the cash value if it is ever needed. The interest credited  (earned) to a cash value policy is normally comparable to  other competing savings instruments such as bonds, bank  CDs, or high yield savings accounts. The major difference  is that life insurance cash values grow tax deferred  inside the policy and can be accessed on a tax-free basis  unlike other savings options.

A Word About Buying Life Insurance

The amount and type of an insurance an individual  should consider buying largely depends the context of that  individual's life. Unless an individual has a good understanding of how life insurance works, and how to cover all of their financial responsibilities, a comprehensive financial review by an insurance agent will probably be necessary.
Many individuals attempt to use online calculators or  quoting software or simply pick an arbitrary amount of  life insurance that they "feel" is the right amount.  However, they could be purchasing too much or too little  insurance.
For example, such factors as personal financial goals, age, annual income, when an individual plans on retiring, total debt (including mortgage debt), number of children, the investment experience of the other spouse, expected pension benefits, expected social security benefits, and so on must all be taken into account when purchasing life insurance.
Even after all of this analyzing is done, the advice of a good financial professional can be invaluable in helping  you figure out how to comfortably afford your new  policy.

Whole life insurance--History ,Terms,Types,Requirements, Guarantees And Liquidity.

Whole Life Insurance, or Whole of Life Assurance (in the Commonwealth), is a life insurance policy that remains in force for the insured's whole life and requires (in most cases) premiums to be paid every year into the policy. 



History























All life insurance was originally term insurance. However, because term life insurance only pays a claim upon death within the stated term, a number of term insurance policy holders became upset over the idea that they could be paying premiums for 20 or 30 years and then wind up with nothing to show for it.
In response to market pressures, actuaries conceived of an insurance policy with level premium payments that were higher than traditional term insurance contracts. These contracts would offer a "cash value", which was designed to be a cash reserve that would build up against the known claim - the death benefit. These policies would also credit interest to the cash value account and upon maturity of the contract (usually at age 95 or 100), the cash value would equal the death benefit.
This produced a benefit to both the policy owner and the insurance company. By guaranteeing the death benefit, the policy owner was assured that insurance coverage would be in force when the insured died. The insurance company benefited because with every premium payment made, 30% is overcharge and pure profit, and thus the cost of insurance, is able to increase, while premiums remain the same.

Types

There are several types of whole life insurance policies. New York State defines six traditional forms: non-participating (aka "non par"), participating, indeterminate premium, economic, limited pay, and single premium. A newer type is known generally as interest sensitive whole life. Other jurisdictions may classify them differently, and not all companies offer all types. There are as many types of insurance policies as can be written in their contracts while staying within the law's guidelines.

Non-Participating

All values related to the policy (death benefits, cash surrender values, premiums) are usually determined at policy issue, for the life of the contract, and usually cannot be altered after issue.
This means that the insurance company assumes all risk of future performance versus the actuaries' estimates. If future claims are underestimated, the insurance company makes up the difference. On the other hand, if the actuaries' estimates on future death claims are high, the insurance company will retain the difference.

Participating

In a participating policy (also par in the USA, and known as a with-profits policy in the Commonwealth), the insurance company shares the excess profits (variously called dividends or refunds in the USA, bonus in the Commonwealth) with the policyholder. Typically these refunds are not taxable because they are considered an overcharge of premium. The greater the overcharge by the company, the greater the refund/dividend. For a mutual life insurance company, participation also implies a degree of ownership of the mutuality.

Indeterminate Premium

Similar to non-participating, except that the premium may vary year to year. However, the premium will never exceed the maximum premium guaranteed in the policy.

Economic

A blending of participating and term life insurance, wherein a part of the dividends is used to purchase additional term insurance. This can generally yield a higher death benefit, at a cost to long term cash value. In some policy years the dividends may be below projections, causing the death benefit in those years to decrease.

Limited Pay

Similar to a participating policy, but instead of paying annual premiums for life, they are only due for a certain number of years, such as 20. The policy may also be set up to be fully paid up at a certain age, such as 65 or 80.The policy itself continues for the life of the insured. These policies would typically cost more up front, since the insurance company needs to build up sufficient cash value within the policy during the payment years to fund the policy for the remainder of the insured's life.

 Single Premium

A form of limited pay, where the pay period is a single large payment up front. These policies typically have fees during early policy years should the policyholder cash it in.

 Interest Sensitive

This type is fairly new, and is also known as either excess interest or current assumption whole life. The policies are a mixture of traditional whole life and universal life. Instead of using dividends to augment guaranteed cash value accumulation, the interest on the policy's cash value varies with current market conditions. Like whole life, death benefit remains constant for life. Like universal life, the premium payment might vary, but not above the maximum premium guaranteed within the policy.

Requirements

Whole life insurance typically requires that the owner pay premiums for the life of the policy. There are some arrangements that let the policy be "paid up", which means that no further payments are ever required, in as few as 5 years, or with even a single large premium. Typically if the payor doesn't make a large premium payment at the outset of the life insurance contract, then he is not allowed to begin making them later in the contract life. However, some whole life contracts offer a rider to the policy which allows for a one time, or occasional, large additional premium payment to be made as long as a minimal extra payment is made on a regular schedule. In contrast, Universal life insurance generally allows more flexibility in premium payment.

 Guarantees

The company generally will guarantee that the policy's cash values will increase regardless of the performance of the company or its experience with death claims (again compared to universal life insurance and variable universal life insurance which can increase the costs and decrease the cash values of the policy).

 Liquidity

Cash values are considered liquid enough to be used for investment capital, but only if the owner is financially healthy enough to continue making premium payments (Single premium whole life policies avoid the risk of the insured failing to make premium payments and are liquid enough to be used as collateral. Single premium policies require that the insured pay a one time premium that tends to be lower than the split payments. Because these policies are fully paid at inception, they have no financial risk and are liquid and secure enough to be used as collateral under the insurance clause of collateral assignment.)Cash value access is tax free up to the point of total premiums paid, and the rest may be accessed tax free in the form of policy loans. If the policy lapses, taxes would be due on outstanding loans. If the insured dies, death benefit is reduced by the amount of any outstanding loan balance.
Internal rates of return for participating policies may be much worse than universal life and interest-sensitive whole life (whose cash values are invested in the money market and bonds) because their cash values are invested in the life insurance company and its general account, which may be in real estate and the stock market. Variable universal life insurance may outperform whole life because the owner can direct investments in sub-accounts that may do better. If an owner desires a conservative position for his cash values, par whole life is indicated.

Environmental Pollution ,And Forms,Sources And Causes,And Effects Of Pollution

Air pollution from World War II weapon production in Alabama
Pollution is the introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms Pollution can take the form of chemical substances or energy, such as noise, heat, or light. Pollutants, the elements of pollution, can be foreign substances or energies, or naturally occurring; when naturally occurring, they are considered contaminants when they exceed natural levels. Pollution is often classed as point source or nonpoint source pollution. The Blacksmith Institute issues annually a list of the world's worst polluted places. In the 2007 issues the ten top nominees are located in Azerbaijan, China, India, Peru, Russia, Ukraine, and Zambia

Ancient cultures

Air pollution has always been with us. According to a 1983 article in the journal Science, "soot found on ceilings of prehistoric caves provides ample evidence of the high levels of pollution that was associated with inadequate ventilation of open fires." The forging of metals appears to be a key turning point in the creation of significant air pollution levels outside the home. Core samples of glaciers in Greenland indicate increases in pollution associated with Greek, Roman and Chinese metal production.

Modern awareness

Pollution became a popular issue after World War II, due to radioactive fallout from atomic warfare and testing. Then a non-nuclear event, The Great Smog of 1952 in London, killed at least 4000 people. This prompted some of the first major modern environmental legislation, The Clean Air Act of 1956.
Pollution began to draw major public attention in the United States between the mid-1950s and early 1970s, when Congress passed the Noise Control Act, the Clean Air Act, the Clean Water Act and the National Environmental Policy Act.
Bad bouts of local pollution helped increase consciousness. PCB dumping in the Hudson River resulted in a ban by the EPA on consumption of its fish in 1974. Long-term dioxin contamination at Love Canal starting in 1947 became a national news story in 1978 and led to the Superfund legislation of 1980. Legal proceedings in the 1990s helped bring to light Chromium-6 releases in California--the champions of whose victims became famous. The pollution of industrial land gave rise to the name brownfield, a term now common in city planning. DDT was banned in most of the developed world after the publication of Rachel Carson's Silent Spring.
The development of nuclear science introduced radioactive contamination, which can remain lethally radioactive for hundreds of thousands of years. Lake Karachay, named by the Worldwatch Institute as the "most polluted spot" on earth, served as a disposal site for the Soviet Union thoroughout the 1950s and 1960s. Second place may go to the area of Chelyabinsk U.S.S.R. (see reference below) as the "Most polluted place on the planet".

Nuclear weapons continued to be tested in the Cold War, sometimes near inhabited areas, especially in the earlier stages of their development. The toll on the worst-affected populations and the growth since then in understanding about the critical threat to human health posed by radioactivity has also been a prohibitive complication associated with nuclear power. Though extreme care is practiced in that industry, the potential for disaster suggested by incidents such as those at Three Mile Island and Chernobyl pose a lingering specter of public mistrust. One legacy of nuclear testing before most forms were banned has been significantly raised levels of background radiation.

International catastrophes such as the wreck of the Amoco Cadiz oil tanker off the coast of Brittany in 1978 and the Bhopal disaster in 1984 have demonstrated the universality of such events and the scale on which efforts to address them needed to engage. The borderless nature of atmosphere and oceans inevitably resulted in the implication of pollution on a planetary level with the issue of global warming. Most recently the term persistent organic pollutant (POP) has come to describe a group of chemicals such as PBDEs and PFCs among others. Though their effects remain somewhat less well understood owing to a lack of experimental data, they have been detected in various ecological habitats far removed from industrial activity such as the Arctic, demonstrating diffusion and bioaccumulation after only a relatively brief period of widespread use.
Growing evidence of local and global pollution and an increasingly informed public over time have given rise to environmentalism and the environmental movement, which generally seek to limit human impact on the environment.

Forms of pollution

The Lachine Canal in Montreal Canada, is polluted.
The major forms of pollution are listed below along with the particular pollutants relevant to each of them:
  • Air pollution, the release of chemicals and particulates into the atmosphere. Common gaseous air pollutants 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. Particulate matter, or fine dust is characterized by their micrometre size PM10 to PM2.5.

  • Light pollution, includes light trespass, over-illumination and astronomical interference.
  • Littering
  • Noise pollution, which encompasses roadway noise, aircraft noise, industrial noise as well as high-intensity sonar.
  • Soil contamination occurs when chemicals are released by spill or underground leakage. Among the most significant soil contaminants are hydrocarbons, heavy metals, MTBE, herbicides, pesticides and chlorinated hydrocarbons.
  • Radioactive contamination, resulting from 20th century activities in atomic physics, such as nuclear power generation and nuclear weapons research, manufacture and deployment. (See alpha emitters and actinides in the environment.)
  • 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.
  • 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.
  • Water pollution, by the release of waste products and contaminants into surface runoff into river drainage systems, leaching into groundwater, liquid spills, wastewater discharges, eutrophication and littering.

Pollutants

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.

Sources and causes

Air pollution comes from both natural and man made sources. Though globally man made pollutants from combustion, construction, mining, agriculture and warfare are increasingly significant in the air pollution equation.
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. Principal stationary pollution sources include chemical plants, coal-fired power plants, oil refineries,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. Agricultural air pollution comes from contemporary practices which include clear felling and burning of natural vegetation as well as spraying of pesticides and herbicides
About 400 million metric tons of hazardous wastes are generated each year. The United States alone produces about 250 million metric tons.Americans constitute less than 5% of the world's population, but produce roughly 25% of the world’s CO2, and generate approximately 30% of world’s waste. In 2007, China has overtaken the United States as the world's biggest producer of CO2.
In February 2007, a report by the Intergovernmental Panel on Climate Change (IPCC), representing the work of 2,500 scientists from more than 130 countries, said that humans have been the primary cause of global warming since 1950. Humans have ways to cut greenhouse gas emissions and avoid the consequences of global warming, a major climate report concluded. But in order to change the climate, the transition from fossil fuels like coal and oil needs to occur within decades, according to the final report this year from the UN's Intergovernmental Panel on Climate Change (IPCC).
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. In 2001 a series of press reports culminating in a book called Fateful Harvest unveiled a widespread practice of recycling industrial byproducts into fertilizer, resulting in the contamination of the soil with various metals. 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. There have also been some unusual releases of polychlorinated dibenzodioxins, commonly called dioxins for simplicity, such as TCDD.
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

Overview of main health effects on humans from some common types of pollution.
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. An estimated 700 million Indians have no access to a proper toilet, and 1,000 Indian children die of diarrhoeal sickness every day. Nearly 500 million Chinese lack access to safe drinking water.656,000 people die prematurely each year in China because of air pollution. In India, air pollution is believed to cause 527,700 fatalities a year. Studies have estimated that the number of people killed annually in the US could be over 50,000.
Oil spills can cause skin irritations and rashes. Noise pollution induces hearing loss, high blood pressure, stress, and sleep disturbance. Mercury has been linked to developmental deficits in children and neurologic symptoms. Older people are majorly exposed to diseases induced by air pollution. Those with heart or lung disorders are under additional risk. Children and infants are also at serious risk. Lead and other heavy metals have been shown to cause neurological problems. Chemical and radioactive substances can cause cancer and as well as birth defects.

Environment

Pollution has been found to be present widely in the environment. There are a number of effects of this:
  • Biomagnification describes situations where toxins (such as heavy metals) may pass through trophic levels, becoming exponentially more concentrated in the process.
  • Carbon dioxide emissions cause ocean acidification, the ongoing decrease in the pH of the Earth's oceans as CO2 becomes dissolved.
  • The emission of greenhouse gases leads to global warming which affects ecosystems in many ways.
  • Invasive species can out compete native species and reduce biodiversity. Invasive plants can contribute debris and biomolecules (allelopathy) that can alter soil and chemical compositions of an environment, often reducing native species competitiveness.
  • Nitrogen oxides are removed from the air by rain and fertilise land which can change the species composition of ecosystems.
  • Smog and haze can reduce the amount of sunlight received by plants to carry out photosynthesis and leads to the production of tropospheric ozone which damages plants.
  • Soil can become infertile and unsuitable for plants. This will affect other organisms in the food web.
  • Sulphur dioxide and nitrogen oxides can cause acid rain which lowers the pH value of soil.

Environmental health information

The Toxicology and Environmental Health Information Program (TEHIP) at the United States National Library of Medicine (NLM) maintains a comprehensive toxicology and environmental health web site that includes access to resources produced by TEHIP and by other government agencies and organizations. This web site includes links to databases, bibliographies, tutorials, and other scientific and consumer-oriented resources. TEHIP also is responsible for the Toxicology Data Network (TOXNET®) an integrated system of toxicology and environmental health databases that are available free of charge on the web.
TOXMAP is a Geographic Information System (GIS) that is part of TOXNET. TOXMAP uses maps of the United States to help users visually explore data from the United States Environmental Protection Agency's (EPA) Toxics Release Inventory and Superfund Basic Research Programs.

Geographic information system


A geographic information system (GIS), geographical information system, or geospatial information system is any system that captures, stores, analyzes, manages, and presents data that are linked to location(s). In the simplest terms, GIS is the merging of cartography, statistical analysis, and database technology. GIS may be used in archaeology, geography, cartography, remote sensing, land surveying, public utility management, natural resource management, precision agriculture, photogrammetry, urban planning, emergency management, landscape architecture, navigation, aerial video, and localized search engines.

Environmental geography

Environmental geography

Environmental geography is the branch of geography that describes the spatial aspects of interactions between humans and the natural world. It requires an understanding of the dynamics of geology, meteorology, hydrology, biogeography, ecology, and geomorphology, as well as the ways in which human societies conceptualize the environment.
The links between cultural and physical geography were once more readily apparent than they are today. As human experience of the world is increasingly mediated by technology, the relationships have often become obscured.
Environmental geography represents a critically important set of analytical tools for assessing the impact of human presence on the environment by measuring the result of human activity on natural landforms and cycles.
Environmental geography is one of three branches of geography: environmental, physical and human. Environmental geography concentrates on the relationship between human and the surrounding world.

iPhone

apple-iphone-keyboard
The iPhone (pronounced /ˈaɪfoʊn/ EYE-fohn) is a line of Internet and multimedia-enabled smartphones designed and marketed by Apple Inc. The first iPhone was introduced on January 9, 2007.
An iPhone can function as a video camera, camera phone with text messaging and visual voicemail, a portable media player, and an Internet client with e-mail, web browsing, and both Wi-Fi and 3G connectivity. The user interface is built around the device's multi-touch screen, including a virtual keyboard rather than a physical one. Third-party as well as Apple applications are available from the App Store, which launched in mid-2008 and now has well over 300,000 "apps" approved by Apple. These apps have diverse functionalities, including games, reference, GPS navigation, social networking, security and advertising for television shows, films, and celebrities.
There are four generations of iPhone models, and they were accompanied by four major releases of iOS (formerly iPhone OS). The original iPhone was a GSM phone which established design precedents like screen size and button placement that have persisted through all models. The iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS added a compass, faster processor, and higher resolution camera, including video. The iPhone 4 has two cameras for FaceTime video calling and a higher-resolution display. It was released on June 24, 2010. On January 11, 2011, Apple and Verizon together launched a CDMA2000 compatible iPhone 4 specifically for the Verizon network in the US, released on February 10, 2011.

Included items

All iPhone models include written documentation, and a dock connector to USB cable. The original and 3G iPhones also came with a cleaning cloth. The original iPhone included stereo headset (earbuds and a microphone) and a plastic dock to hold the unit upright while charging and syncing. The iPhone 3G includes a similar headset plus a SIM eject tool (the original model requires a paperclip). The iPhone 3GS includes the SIM eject tool and a revised headset, which adds volume buttons (not functional with previous iPhone versions)..The iPhone 3G and 3GS are compatible with the same dock, sold separately, but not the original model's dock. All versions include a USB power adapter, or "wall charger," which allows the iPhone to charge from an AC outlet. The iPhone 3G and iPhone 3GS sold in North America, Japan, Colombia, Ecuador, or Peru include an ultracompact USB power adapter.
