::The Crying Earth::

Global warming is a condition when our surrounding had an increasing in temperature rather than normal. This situation will make night becomes hotter than usual. This is happen because of human activities such are deforestation, industrial activity, open burning, smoke, exploration to forest that is for building projects and many more.

Mistakes that human did to the environment cause many negative effects. One of them is the melting phase in North Pole higher, sea level increase and the size of land becomes smaller. Besides that, natural earth disaster may occurred like flood and fire burning meanwhile human activities including death and injured.

Scientist and georaphyist decided that the main factors that lead to the global warming is decreasing of ozone layer that is causes by emission of gases especially chlorofluorocarbon (CFC).
Actually, issues of increasing temperature occurred causes of many factor. Other than ozone layer becomes more thin, haze, island of heat, acid rain and green house effect also give their contribution to the global warming.

Let’s take a look on how global warming occurs based on every process that is represent here.


Haze

Hazes happen when a lot of smoke, smug, dust and others because of human activities or naturally occur. This phenomenon can decrease the distance of our view. Moreover, haze can raise the number of disease. For example hard to breath.

Ozone Depletion

Chlorofluorocarbons (CFC) that is the greatest contributors to this phenomenon. CFC gases can contains in air conditioning, aerosol and refrigerator. When the CFC gases is emitted to the atmosphere, chlorine can attack the ozone and released oxygen. Consequently, ozone layer becomes thinner. This situartion will make an ultraviolet ray reach up to the earth surface directly and give the bad effects to the human such as skin cancer and katarak.

Greenhouse Effects

Occurs when more energy is trapped in the atmosphere layer and discards the energy back to the atmosphere. Heat is reflected again to the earth, atmosphere are keep more heat and that is make our earth becomes more warmer. Greenhouse effects happen because increasing of emission of gases such as carbon dioxide, nitrogen monoxide and methane to the earth.

Acid Rain

Factory released gases that are contains sulphur dioxide and nitrogen dioxide. The reaction of these gases with the water vapour in air will formed nitric acid and sulphuric acid. Then when raining takes place, it is called as acid rain.

As the precaution steps, the thing we can do are:
1. Switch off the electric.
2. Change the types of light that is suitable with the electrical energy.
3. Clean out the fan or light.
4. Use timer ( for AC, microwave, oven, magic jar, and many more ).
5. Plant trees in our house.
6. Hang cloth under the sun ray.
7. Use public transport.
8. Save the usage of papers.
9. “Say no to plastic”.


As a conclusion, we as people that live on this earth should take an action to decrease the global warming. The effects from this phenomenon will damaged the world systems because it can increase the sea level, changing of the glasier and biosphere also changing in weather pattern.
