Climate Change !

climate is the variation in temperature, evaporation, and wind over a certain period in months, even thousands of years. earth climate is strongly influenced by the heat balance on earth by radiation emitted by the sun. from all over the earth radiation, a third reflected back into space by Earth's atmosphere and surface.
Two-thirds of the radiation that is not reflected, the amount of about 240 Watt/m2, absorbed by the earth's surface and atmosphere. To maintain a balance of heat, the earth radiates back to the heat absorbed in the form of short-wave radiation. Some short-wave radiation emitted by Earth is absorbed by certain gases in the atmosphere are called greenhouse gases. Furthermore, the greenhouse gases radiate heat back to earth. This mechanism is called the greenhouse effect. The greenhouse effect is what causes the earth's temperature is relatively warm with an average of 14oC, without the greenhouse effect the earth's temperature is only about-19oC.

Say No To ILLEGAL LOGGING !

besides global warming, illegal logging must also be destroyed. illegal logging is the felling of trees without permission from the government. or tantamount to stealing the tree without permission. illegal logging is very much an impact to humans. World Bank data released since the year 1985-1997 shows that Indonesia has lost about 1.5 million hectares of forest each year and an estimated 20 million remaining production forests. illegal logging occurs because of increased demand for wood in the international market. given the impact is also very much. including:
1. occurrence of floods and landslides.
2. reduction in spring in the forest
3. reduction in the fertile soil layer
4. destruction of fauna and flora

illegal logging can also cause death. landslides can accumulate a lot of people, flooding that can wash away people, and so forth. should, we should not cut down trees at random. if we cut down trees, then we must do revegetation (reforestation).
