Learning English

English is a universal language and is spoken in many countries in the world. English is the official language of 45 countries in the world. Communication is very important in today's time; English provides the medium for all the cultures to communicate through books, movies, plays, the computer world, internet or other resources. English can be at least understood almost everywhere among scholars and educated people, All over the planet people know many English words, their pronunciation and meaning. Many companies in today's time require their employees to be well versed with English, so that they can communicate with the company's international clients. In such a situation, employees with good command on the language are at an advantage. All computer languages use English as its base language, so one needs to know Basic English to be an IT professional. This is why learning English is really important for a person in these times.
English is safe the time and if it is not most spoken language in the world but it is international language in the world. i think that it is easy to learn, easy to read, easy to write, and easy to speak. so we should learn English language for our better life purpose
The concept of a Universal Language is more significant only now, in the era of world mass communication. Before this era Greek, Latin, French were to some extent universal languages, though mainly in Europe. By a lucky coincidence due to factors above, English, the Universal language, is one of the simplest and easiest natural languages in the world. The only other simple and easy languages are constructed ones.
First of all, English Language uses Latin alphabet, the most universal, simple and short one (only the Greek alphabet is shorter and simpler). In addition, in English, the Latin Alphabet presents its most "clean" form as a true alphabet with only 26 basic letters and no diacritics; Verb conjugation is very simple and easy. Even for irregular verbs, there is almost no variation in person (except 3rd singular in present tense).
Regular verbs have only four forms: Infinitive + Present, Past Tense + Past Participle, 3rd person singular Present Indicative, Present Participle.
Why do people learn English?
1. English may not be the most spoken language in the world, but it is the official language in a large number of countries. It is estimated that the number of people in the world that use in English to communicate on a regular basis is 2 billion
2. English is the dominant business language and it has become almost a necessity for people to speak English if they are to enter a global workforce, research from all over the world shows that cross-border business communication is most often conducted in English. Its importance in the global market place therefore cannot be understated
3. Many of the world’s top films, books and music are published and produced in English. Therefore by learning English you will have access to a great wealth of entertainment and will be able to have a greater cultural understanding.
4. Most of the content produced on the internet (50%) is in English. So knowing English will allow you access to an incredible amount of information which may not be otherwise available
5. When travel to different countries, English is often the most common “bridge” language. Meaning that you could meet with people from five different countries at the same time and it is likely the only common language between all five people is English. English is able to connect people from many different countries and cultures more so than other languages. English is also a common language in tourism worldwide. If you want to take a tour of different historical places or go to a hotel in the Caribbean; English is usually what the majority of the staff or workers know how to speak besides their local or native language.

Global Warming

Often the people who complained about the perceived hot weather, you are not wrong because the data are indeed showed the planet continues to experience alarming increase in temperature from year to year. Advances in technology are rapidly evolving, many produce some sophisticated products that it actually creates an atmosphere and environment that is not environmentally friendly. Many office buildings and housing built makes the least space for greening. Besides the many natural phenomena that tend to be getting out of control lately. Ranging from flood, tornado, blowouts, until the rainfall is erratic from year to year.
Be aware that all of these are natural signs that indicate that our beloved planet is currently undergoing a process of damage that leads to destruction. This is directly related to global issues more intense lately discussed by the world community, namely Global Warming or Global Warming.
Global Warming or Global Warming is the increase of temperature average of the atmosphere, ocean and land Earth. At this time the Earth is warming rapidly, which by scientists considered to be caused by human activity. As a result of the heat of the earth that lead to high evaporation and precipitation fell in erratic. The main cause is the burning of fossil fuels, such as coal, petroleum, and natural gas, which releases carbon dioxide and other gases that dikelan as a greenhouse gas into the atmosphere (Darsono, 1993).
The causes of global warming:
1. Greenhouse Effect
All energy sources that exist on Earth comes from the sun. Most of the energy is in bentukradiasi short waves, including visible light. When this energy on the Earth's surface, he turned on the light into heat that warms the Earth. Earth's surface will absorb some of the heat and reflect the rest. Some of this heat as long-wave infrared radiation into space. However, some heat remains trapped in the earth's atmosphere due to the accumulated amount of greenhouse gases include water vapor, carbon dioxide, and methane that become traps for this radiation.
These gases absorb and reflect radiation emitted by the Earth and consequently the heat stored in the Earth's surface. This happens repeatedly and resulted in an annual average temperature of the earth continues to increase. These gases functioning as the glass in a greenhouse. With the increasing concentration of these gases in the atmosphere, the more heat is trapped below. Actually, the greenhouse effect is very much needed by all living things on earth, because without it, the planet would be very cool. So that the ice will cover the entire surface of the Earth. However, due to the amount of these gases in the atmosphere has been excessive, be a consequence of global warming.
2. Effects Feedback
The effects of global warming-causing agents are also influenced by various feedback processes that result. An example is the evaporation of water. In the case of warming caused by greenhouse gases such as CO2, warming will initially cause greater volumes of water that evaporates into the atmosphere. Because water vapor is itself a greenhouse gas, warming will continue and increase the amount of water vapor in the air until it reaches equilibrium with the water vapor concentration. The resulting greenhouse effect greater than the effect of CO2 alone. (Although this feedback raises the absolute water content in the air, the relative humidity of the air is almost constant or even fall because the air becomes warm). This feedback can be reversed only slowly because of CO2 have longevity in the atmosphere.
Feedback effects due to the influence of clouds is the subject of current research. When viewed from below, clouds will reflect infrared radiation back to the surface, thereby increasing the warming effect. In contrast when viewed from above, the clouds will reflect sunlight and infrared radiation into space, thereby increasing the cooling effect. Is the net effect of heating or cooling depends on some specific details such as the type and height of these clouds. These details are difficult to represent in climate models, partly because the clouds are very small compared to the distance between the boundaries of computational climate models (around 125 to 500 km for models used in the IPCC Fourth Report of view.
Another important feedback is the loss of reflectance (albedo) by ice. When global temperatures rise, ice near the poles melts at an increasing rate. Together with the melting of the ice, land or water below opens. Both land and water has the ability to reflect light much less when compared to ice, and consequently will absorb more solar radiation. This will add to warming and causing even more ice to melt, causing a continuous cycle.
Positive feedback due to release of CO2 and CH4 from the softening of frozen ground (permafrost) are other mechanisms that contribute to warming. In addition, the ice that melts will also release CH4 which also give rise to positive feedback. The ability of the oceans to absorb carbon will also be reduced when he warmed up, this is caused by the decline in the level of nutrients in the mesopelagic zone, limiting the growth of phytoplankton diatoms rather than a carbon sink that low.
The impact of global warming facts lead to rising sea levels, climate change, damage to organisms and ecosystems, and influence on water availability and agriculture. The rise in the average temperature of the earth is one of evidence for climate change. According to the IPCC (Intergovernmental Panel on Climate Change) the average global temperature will increase at a rate of 0.3 derat Celsius per decade. It is estimated for 2030 to 2050 the average global temperature rose 1.50 up to 4.5 degrees Celsius even be 50 in 2100.
This temperature rise resulted in glaciers on the poles of the earth melts. Ice earth will melt into the sea water and add sea level. If the CO2 concentration increases 2-4kali of current conditions in the span of 100 years would raise sea level approximately 0.25 m.
We certainly realize how hot the temperature around us lately. We can also see how no predictability arrival of the rainy season or drought which resulted in losses for farmers because the growing season is supposed to be done in the dry season turned out to rain. You can also look at cases of extreme storms that have never hit areas in Indonesia terntentu. In recent years we more often hit by storms that disrupt shipping and transport either via sea or air.
The problem now is the high greenhouse gases as a result of human activities that can affect the Earth's climate, causing global warming (Global Warming). Therefore, global climate change affect the state of nature as a whole must be maintained. It is time for the earth to be inhabited rescued longer and comfortable. Many ways can be done to participate in saving the planet, including refrigerators and air conditioners do not use the wok freonnya made of the type of CFC, energy saving, no littering that can produce methane gas, and process waste into compost. In addition, the diversification of energy from renewable fuels (biofuels), greening around the house, and using appropriate technology and environmentally friendly.
Now this has become a problem of global warming along with the countries in the world, where global warming has an impact on climate change and trigger a natural disaster such as a flood, tornado, earthquake, and many other natural phenomena that can endanger human life earth. UNFCCC as one UN agency spearheading a conference to discuss climate change at that time was held in Bali. In fact, Emil Salim estimated that at least 23 tidka uninhabited islands in Indonesia will be immersed in the last 10 years.
Actually attempts to anticipate natural phenomenon caused by global warming is very easy to do, just how consciousness of mankind in the world in preserving and saving the forest. No one seems if the Indonesian government should firmly against illegal logging has been done by people who are not responsible and concerned with personal gain. The government also should immediately re-plan and carry out reforestation programs as he had done in previous years. This program can be done by cooperating institutions easily movable, such as holding military and police, as well as in the countries in the world.
Re-use and Recycling if applicable, the energy saved is enough to provide energy supply for 1.4 million homes, reducing 27,047 tons of water pollution, saves 14 million trees, and reducing greenhouse gas emissions by the equivalent of 3.8 million cars. And also use alternative transportation to reduce carbon emissions.
We really need to begin to practice in daily life. Do a gradual but consistent with our commitment. Hopefully human consciousness in the world for protecting and preserving the environment has always maintained, so that the effects of global warming can be reduced as soon as possible.
