Abu Dhabi is the capital and second largest city of the United Arab Emirates. It is also the capital and largest city of the emirate of Abu Dhabi, which is the largest of the seven emirates of the United Arab Emirates by size. It was said by CNN to be the richest city in the world[1] and is located in the center of the northern part of the United Arab Emirates. The city lies on a T-shaped island jutting into the Persian Gulf from the central western coast. An estimated 1.8 million people lived there in 2006, with about an 80% expatriate population. Abu Dhabi city is located at 24°28′00″N 54°22′00″E / 24.4667, 54.3667. At the head of Abu Dhabi and across from the Corniche is Lulu Island, a semi-natural landmass that is arguably the most strategic and valuable piece of property in the Emirate [2].

Culture and the arts

Abu Dhabi is trying to position itself as the "Cultural hub" of the Middle East, taking this mantle from such neighboring cities as Beirut and Cairo. It is home to a number of cultural institutions including the Cultural Foundation and the National Theater. The Cultural Foundation is home to the UAE Public Library and Cultural Center. Various cultural societies such as the Abu Dhabi Classical Music Society have a strong and visible following in the city.

The creation of a major "up-scale cultural district" on Abu Dhabi's Saadiyat Island has begun with the groundwork for a US$200 million Guggenheim Museum. The Frank Gehry-designed museum will display a "prestige collection" of modernist and contemporary art and is scheduled for completion in 2011. Upon completion, it is expected to be the largest exponent of the prestigious Guggenheim Museums.[9]

Language and literature
The majority of the inhabitants of Abu Dhabi are expatriate workers from India, Pakistan, Egypt, Bangladesh, Philippines, Britain, various countries from across the Arab world and elsewhere. Consequently, English, Tagalog, Tigrinya, Amharic, Bengali, and Urdu are widely spoken. Apart from Hindi, the many Indian expatriates also contribute other South Asian languages to the cultural milieu, including Malayalam, widely spoken in Kerala.

The native-born population are Arabic-speaking Gulf Arabs who are part of a clan-based society. The al-Nahyan family, part of the al-Falah branch of the Bani Yas clan, rules the emirate and has a central place in society.

Location

Satellite image of Abu Dhabi (March 2003)The emirate of Abu Dhabi is located in the oil-rich and strategic United Arab Emirates and is an active member of the Gulf Co-operation Council (GCC). It borders with the Kingdom of Saudi Arabia (south) and the Sultanate of Oman (east). The emirate borders the emirate of Dubai to its northeast. In the north is the Persian Gulf.

Abu Dhabi city is on an island located less than a quarter-kilometer from the mainland and is joined to the mainland by the Maqta and Musaffah Bridges. A third bridge, designed by Zaha Hadid, is currently under construction. Bridges connecting to Reem Island and Saadiyat Island are also under construction.

Most of Abu Dhabi is located on the island itself, but it has many suburbs on the mainland for example: The Khalifa Cities, Between Two Bridges, Mussafah Residential and more.

Carbon is a very important element, as it makes up organic matter, which is a part of all life. Carbon follows a certain route on earth, called the carbon cycle. Through following the carbon cycle we can also study energy flows on earth, because most of the chemical energy needed for life is stored in organic compounds as bonds between carbon atoms and other atoms.
The carbon cycle naturally consists of two parts, the terrestrial and the aquatic carbon cycle. The aquatic carbon cycle is concerned with the movements of carbon through marine ecosystems and the terrestrial carbon cycle is concerned with the movement of carbon through terrestrial ecosystems.

The carbon cycle is based on carbon dioxide (CO2), which can be found in air in the gaseous form, and in water in dissolved form. Terrestrial plants use atmospheric carbon dioxide from the atmosphere, to generate oxygen that sustains animal life. Aquatic plants also generate oxygen, but they use carbon dioxide from water.
The process of oxygen generation is called photosynthesis. During photosynthesis, plants and other producers transfer carbon dioxide and water into complex carbohydrates, such as glucose, under the influence of sunlight. Only plants and some bacteria have the ability to conduct this process, because they possess chlorophyll; a pigment molecule in leaves that they can capture solar energy with.

The overall reaction of photosynthesis is:
carbon dioxide + water + solar energy -> glucose + oxygen
6 CO2 + 6 H2O + solar energy -> C6H12O6 + 6 O2

The oxygen that is produced during photosynthesis will sustain non-producing life forms, such as animals, and most micro organisms. Animals are called consumers, because they use the oxygen that is produced by plants. Carbon dioxide is released back into the atmosphere during respiration of consumers, which breaks down glucose and other complex organic compounds and converts the carbon back to carbon dioxide for reuse by producers.

Carbon that is used by producers, consumers and decomposers cycles fairly rapidly through air, water and biota. But carbon can also be stored as biomass in the roots of trees and other organic matter for many decades. This carbon is released back into the atmosphere by decomposition, as was noted before.
Not all organic matter is immediately decomposed. Under certain conditions dead plant matter accumulates faster than it is decomposed within an ecosystem. The remains are locked away in underground deposits. When layers of sediment compress this matter fossil fuels will be formed, after many centuries. Long-term geological processes may expose the carbon in these fuels to air after a long period of time, but usually the carbon within the fossil fuels is released during humane combustion processes.
The combustion of fossil fuels has supplied us with energy for as long as we can remember. But the human population of the world has been expanding and so has our demand for energy. That is why fossil fuels are burned very extensively. This is not without consequences, because we are burning fossil fuels much faster than they develop. Because of our actions fossil fuels have become non-renewable recourses.

Although the combustion of fossil fuels mainly adds carbon dioxide to air, some of it is also released during natural processes, such as volcanic eruptions.

In the aquatic ecosystem carbon dioxide can be stored in rocks and sediments. It will take a long time before this carbon dioxide will be released, through weathering of rocks or geologic processes that bring sediment to the surface of water.
Carbon dioxide that is stored in water will be present as either carbonate or bicarbonate ions. These ions are an important part of natural buffers that prevent the water from becoming too acidic or too basic. When the sun warms up the water carbonate and bicarbonate ions will be returned to the atmosphere as carbon dioxide.

Carbon dioxide (greenhouse gas)
As many people know carbon dioxide is a greenhouse gas, which basically means that too much carbon dioxide in air causes the earth to warm up.
Humans emit great amounts of carbon dioxide during combustion processes and because of this, the greenhouse effect consisted. The greenhouse effect means that the climate is affected by the concentrations of greenhouse gasses on earth.
In the past few decades a warmer climate has developed, because of the large amounts of carbon dioxide and other greenhouse gases that we emit. This warmer climate can cause problems, such as the melting of large ice formations at the Arctic's.
