					                                         GLOBAL WARMING
        Since ancient times human beings up to the present age, man has always experienced growth in
every period of time passed. Human civilization has undergone a lot of progress now. During
development, the human being living and being dependent on farming and agriculture. Through the life
orientation, man has always tried to maintain and preserve the environment as well as possible aiming
to maintain the continuity of human life.

        Humans now have experienced the industrial revolution that made the life in the fields of
industry. By using the life orientation, world agriculture was declining slowly. The values of human life
underwent a change, especially in human interaction with the environment. The changes that occurred
resulted in positive and negative impacts. One of the effects of the industrial revolution that has
occurred and is still continuing on the present life and human civilization is its impact on the
environment that exists around the man himself.

         Expansion of the efforts made by industry players such as the construction of factories and
manufacture large-capacity production to the exclusion of concern for its impact on the environment is
slowly but surely have resulted in omission that will ultimately harm the environment and human
habitation kehidupannya.Para environmental experts have found indications of the impact on the
environment and the world's largest global industrial business due to be done and has been growing
rapidly at this time.

       This negative impact is the warming of the world and is often referred to as Global Warming.
However, the problem of Global Warming as an environmental issue is still debated its truth by some
who think Global Warming is a reason that was created to limit the pace of industrial development.
Although there is still debate about the true state of Global Warming among environmental experts, the
Global Warming issue is not can diungkiri to be researched and further investigated for the continuation
of human life.

        Global Warming or Global Warming is the process of increasing the average temperature
of the atmosphere, oceans, and Earth's land.

Global average temperature at Earth's surface has risen 0.74 ° C ± 0:18 (1:33 ± 0:32 ° F) during
the last hundred years. Intergovernmental Panel on Climate Change (IPCC) concluded that,
"most of the increase in global average temperatures since the mid-20th century is most likely
caused by increased concentrations of greenhouse gases due to human activities" [1] via the
greenhouse effect. These basic conclusions have been advanced by at least 30 scientific and
academic bodies, including the national science academies of all G8 countries.
         However, there are still some scientists who disagree with some of the IPCC conclusions
are presented.
Climate models referenced by the IPCC project suggests global surface temperatures will rise 1.1
to 6.4 ° C (2.0 to 11.5 ° F) between 1990 and 2100.Perbedaan estimates was caused by the use of
different scenarios on emissions of greenhouse gases in the future, as well as models of different
climate sensitivities. While most research focuses on the period up to 2100, warming and sea
level rise is expected to continue for more than a thousand years even if greenhouse gas emission
levels have been stabil.Ini reflects the large heat capacity of the oceans.
         Increasing global temperature is expected to lead to other changes such as rising sea
levels, increased intensity of extreme weather phenomena, as well as changes in the number and
pattern of precipitation. Consequences of global warming is terpengaruhnya other crops, the loss
of glaciers, and the extinction of various animal species.

        Causes of Global Warming
     1. Greenhouse effect
All energy sources that exist on Earth comes from the Sun. Most of the energy in the form of short-wave
radiation, including visible light. When this energy arrives Earth's surface, he turned from the light into
heat that warms the Earth. Earth's surface, will absorb some heat and reflecting back the rest. Much of
this heat is tangible long-wave infrared radiation into space.

But some of the heat remains trapped in Earth's atmosphere due to accumulated amount of greenhouse
gases such as water vapor, carbon dioxide, sulfur dioxide and methane which trap this radiation. These
gases absorb and reflect radiation emitted wave and consequently the Earth's heat is stored in the
Earth's surface. This situation occurs continuously, resulting in an annual average temperature of the
earth continues to increase.

2. Feedback effect
nasir cause of global warming are also influenced by various feedback processes that result. An example
is the evaporation of water. In the case of warming due to increasing greenhouse gases such as CO2,
warming will initially lead to more amount 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 an equilibrium concentration of water vapor.

The resulting greenhouse effect is greater than the effect of CO2 alone. (Although this feedback
increases the absolute water content in the air, relative humidity of air is almost constant or even
decreases slightly because the air becomes warmer). [3] This feedback effect only slowly as CO2 has a
long age in the atmosphere. Another important feedback is the loss of the ability to reflect light (albedo)
of ice. [4] When global temperatures increase, ice near the poles melts at an ever increasing. Along with
the melting of the ice, land or water below it will open. Both land and water has the ability to reflect
light much less when compared to the ice, and consequently will absorb more solar radiation. This will
increase the heating and causing even more ice melts, it becomes a continuous cycle

Global warming accelerates the spread of disease

Global warming is now reached an alarming level. Yet another insidious problem that we need to be
aware of is the rising earth temperature will result in a number of pandemic microbe - microbe and virus
- the virus began to spread in the human environment and animals.

A. Avian Influenza

Such as human influenza, avian influenza viruses occur naturally in wild birds, but not dangerous. These
viruses enter the bird through the feces and secretions. Birds can transmit the virus from domestic birds
or wild birds. The high levels of pathogenic H5NI disease is a major concern for governments and
healthcare organizations today, because it is deadly to wild birds, humans. Even the original
transmission of the virus from birds to humans only can increase from human to human. Movement of
H5N1 from country to country are usually from the poultry trade. But climate change such as severe
winter storms that can disrupt the normal movement of wild bird populations, and can bring both wild
and domesticated birds is toward the water source close to humans.

2. Cholera
Cholera is a diarrheal disease caused by water that affect humans, especially in developing countries. It
is caused by a bacterium, Vibrio cholerae, which persist in small organisms in contaminated water
sources and may also appear in the form of raw shellfish such as oysters. Once infected, cholera quickly
becomes deadly. This is very dependent on temperature, and water temperature rise directly.

3. Ebola
Ebola virus hemorrhagic fever virus and is very close to the Marburg fever virus is easily kill humans,
gorillas, and chimpanzees, and currently no known cure. Scientists continue to work to find the source
of the disease and to develop a vaccine for protection. There is significant evidence that outbreaks of
both diseases are related to unusual variations in rainfall / dry season patterns. Such as climate change
and extreme seasons.

4. External parasites and Guts
Parasites are widespread throughout the living terrestrial and aquatic environments. On temperature
and rainfall with a high level of shifting seasons, the survival of parasites in the environment will
increase in many areas, an increasing number of human and animal infections. Many types of parasites
are zoonotic, spread between wildlife and humans. Nematode, Baylisascaris procyonis, is spread by the
common raccoon and is deadly to many other species of wildlife and humans.

5. Plague
Plague, Yersinia pestis - one of the oldest infectious diseases known-still causes significant death rates in
wildlife, domestic animals, and humans in a particular location. This plague spread by rats and fleas.
Changes in temperature and rainfall change the distribution of rat populations around the world, which
will impact on the rodent-born diseases such as plague
6. Rift Valley Fever
Rift Valley fever virus (RVFV) is a zoonotic disease that appears to significantly interfere with public
health, food security and economic interests as a whole, particularly in Africa and the Middle East. In the
infected animals such as cattle, sheep, goats and camels, abortions and high death rates is a matter of
course. In people (who could be infected with the virus from butchering infected animals), the disease
can be fatal. Given the role of mosquitoes in transmission of the virus, climate change continues to be
associated with fears of the spread of RVFV.

7. Tuberculosis
Bovine tuberculosis spread through the movement of livestock throughout the world. Now has a global
distribution and problematic, especially in Africa, where he was introduced by European livestock in the
1800's. This disease infects vital wildlife populations, such as buffalo and lions in Kruger National Park in
South Africa, where tourism is an integral part of the local economy. This disease also infects humans in
southern Africa through the consumption of unpasteurized milk. Human forms of tuberculosis can also
infect wild animals. Impacts of climate change on water availability due to drought are likely to increase
the contact of wildlife and livestock at limited water sources, resulting in increased disease transmission
between livestock and wildlife and livestock and humans.

8. Yellow fever
Found in tropical Africa and parts of Central and South America, the virus is carried by mosquitoes,
which will spread to new areas as changes in temperature and precipitation levels above the normal
threshold. One type of jungle yellow fever virus can be spread from primates to humans and vice versa
via mosquitoes that take blood of humans and primates. Recent outbreaks in Brazil and Argentina have
a devastating impact on wild primate populations. In some countries in South America, monitoring of
wild primates has resulted in early detection of disease activity and allows for rapid vaccination program
and should be implemented to protect humans.

        Here's What We Must Do

There are various ways to slow global warming, these methods are generally easy and simple. But not
done seriously by most people.

A. Limit the usage of paper

Embed this in your mind firmly, that each time you use a piece of paper then you've cut down a tree.
Therefore, use the paper as effective as possible for example to print the print out back and forth on
each paper. When you are jamming print something that is not too important, use scrap paper that
behind it is still empty.

2. Replace light bulbs.

Immediately replace your incandescent bulbs with fluorescent bulbs. The fluorescent lamp requires less
energy than incandescent bulbs. Remember all the power you use it you participate in electric energy
resources are spent mostly fossil fuel. Fossil fuels are nonrenewable fuels, and within the next ten years
this type of fuel may be exhausted.

3. Open the windows wide

In America, most of the 22.7 tonnes of CO2 emissions come from home. Most emissions or flue gas from
the air conditioner, refrigerator, gas stove or refrigerator. Fatherly minimize it when it can set the AC
thermostat with outdoor air temperature. Then open the windows wide open because of trapped air
circulation can consume energy.

4. Use an organic fertilizer.

Most farmers used fertilizer containing nitrogen element, which then turned into the N2O effect of GHG
(Greenhouse Gas) 320 times greater than CO2. If you use organic fertilizer gardening hobby. Besides
safe, inexpensive, too.

5. Plant the bamboo grove

The trees are proven to absorb CO2, but it was a tree or bamboo clump can absorb four times more CO2
than other trees.

6. Taking public transportation

Currently the number of private vehicles has been very much and make stuffy. Transportation sector
accounts for up to 14% of greenhouse gas emissions into the atmosphere, if we use common vehicles
we reduce greenhouse gas emissions,

7. Do not use plastic bags

In some American states, affairs and even plastic bags made of all laws. NGOs concerned about the
environment encourages local governments, fatherly prohibit the use of plastic bags as shopping bags.
This plastic is a difficult element decomposes, it took 1000 years to mengurainya in the soil.

Greenhouse gas effect is also caused considerable. Then switch to cloth bags, for example from a natural
fiber fabrics.

8. Efficient life

Any human activity on earth will have an impact on the earth we live. Energy consumption patterns,
environmental patterns and so on. Live as efficiently as possible, use less energy, less food komsumsilah,
leave a consumptive lifestyle, kind to the environment, talk a little more thought, and so forth.
9. Intelligent driving

Avoid long trips and spend time, if possible cut do. Reduce activities that use private vehicles. If forced
to use a private vehicle, choose the alternative roads are jam-free and does not consume energy. If you
wait, stop the engine because the exhaust gas remains out of fuel while the materials used.

                                           messages from earth

              “if I could talk I would say I take care of me was hospitalized and I was rescued.
                                Because I have to provide exactly what you need”
