Global warming became an environmental issue becomes a problem for the entire population of earth in all parts of the world. Global warming is the increase in average temperature at Earth's surface, whether on land, above sea level, and at the poles. Global warming caused by heat coming from the sun that should warm the earth, many reflected back into the layers of the earth's atmosphere because the greenhouse effect. Heat energy which is the source of life on earth through plants now can not be fully utilized because of the transition functions of forests into industrial and residential areas. Illegal logging cause deforestation should empower the heat energy from the sun. Use of air conditioner that produces CO2 which causes more heat and increasing skyscraper buildings that use the main ingredient of glass on the outside of the building that reflects heat back into Earth's atmosphere. This causes the thin ozone layer that protects and became a filter for the planet earth from ultraviolet rays, so the heat in the earth's surface growing by day.
The effect of global warming is the increasing thinness of the ozone layer, resulting in increased temperatures on the surface of the earth. Many of the effects of increased temperature on the surface of the earth, one of which is climate change. Currently climate calendar has been shifted. Climate change also resulted in the extinction of a variety of flora and fauna being unable to adapt to climate change is happening. Moreover, forests are a breeding ground for flora and fauna at this time many of exploitation by humans. Illegal logging is increasingly a lot, which causes the forest to be bald. If flora and fauna many of which became extinct, the human survival could be threatened if the balance is not maintained, because humans also have a dependency with a variety of flora and fauna which is the source of energy for humans. Global warming also causes the melting of ice at the poles of the earth so that surface water is increasing. Mainland-sea ice in both poles of the earth began to thaw. If this continues to happen is not impossible that all the lands on earth will be submerged.
One way to reduce global warming is a re-forestation of the lungs of the world so that the heat of the sun can be empowered as it should and as much as possible for our survival and subsequent generations are not threatened. Making city parks also have been developed for growing plants that can bind and neutralize a lot of pollution produced by motor vehicles is becoming an important issue for human survival in the urban areas.
Actually global warming is not always bring bad effects to human life. In cold areas in countries such as Canada, global warming makes the fields there into fertile. This is because in cold regions like Canada not getting enough heat. So with global warming there actually get hot enough, the spring growing old, and agricultural output is increasing.
So humankind must be able to control global warming that happened. Do not let this get worse and threaten the survival of the entire population of earth. People must begin to realize and care about the environment they live for the survival of subsequent generations can be saved.
