Chlorofluorocarbons (CFCs)

CFCs or chlorofluorocarbons are chemicals consisting of a combination of three organic compounds, ie carbon, chlorine, floor. He often used for aerosol cans, aluminum trays that resemble hamburger, refrigerator, and similar items that it can destroy life on earth.
CFCs is becoming obsolete in recent years as shown to cause damage to vital ozone layer by attacking the stratosphere.

If you are looking for items based CFCs today is rather difficult. He had long passed from human life. Such materials are prohibited to use in most industrialized countries since the treaty in mid-1990. The policy followed by the developing countries, including Indonesia.

CFCs is a chemical that breaks down tough and long-lived. As with plastic, they remain around us and continue to exacerbate the atmosphere. In most products, CFCs have been replaced by the position of HCFC, CFCs are also similar substances made of water. Also known as the freon.

But the good news, the situation today is much better. International scientific body composed of approximately 300 senior scientists, Scientific Assessment of Ozone depletion, reported for the first time in the fall of this year CFC12 content decreases in the ozone layer.

The report emphasized that most of the ozone layer in the earth will return to normal by mid-century, circa 2050. Except, the open hole in the Antarctic. It's not impossible, but it's hard to go back to normal because it takes a longer time.

The good news is not only good for human health, but also resistance on the issue of global warming. As the winds of heaven in the middle of the international climate negotiations deadlock.

Ozone, a bluish-colored substance and form of oxygen, has a fragile defense. Oddly, though not strong it works really effectively. Dispersed throughout the earth 21 miles below the stratosphere, ozone protects all life on Earth from harmful ultraviolet radiation delivered sun.
