Air PollutionAir pollution can be caused by natural sources and human activities. Some of the physical definition of interference like sound pollution, heat, radiation or light pollution is considered as air pollution. Nature air cause air pollution impacts can be direct and local, regional, and global. Air pollution can be divided into primary and secondary pollution. Pollution is a primary substance of pollution caused directly from the source of air pollution. Carbon monoxide is an example of air pollution because it is the primary result of combustion. Pollution is a secondary substance made from pollution reaction pollutions primary in the atmosphere. The formation of ozone in smog Fotokimia is an example of secondary air pollution. The atmosphere is a system of complex, dynamic, and fragile. Later this growth will concerns the effects of air pollution emissions in a global context and relationship with global warming, climate change and ozone depletion in stratosphere increasing. The impact of health Air Pollution that there is substance in the air can enter the body through the respiratory system. Increased penetration of substances in the body Pollution to depend on the type of Pollution. Particulate large can be restrained at the top of the respiratory channel, while particulate is small and gas can reach the lungs. From the lungs, oxygen absorbed by Air Pollution circulatory system and spread to the entire body. Impact on plant Plant that grows in areas with high air pollution levels can be subject to growth and prone to disease, among others clorosis, necrosis, and black spot. Particulate the deposition on the surface can hinder the process of plant photosynthesis.

Forest Deforestation

Forest DeforestationForest deforestation is a condition where the level of forest area that showed a decline both in terms of quality and quantity. For Example, Indonesia has a 10% world's tropical forests remaining. Forest has 12% of the number of species of mammals,16% the animal species of reptiles and amphibian, 1519 bird species and 25% of the world's fish species. Some of them are endemic or can only be found in the area. Area of natural forest with native Indonesia wipe speed which is very worrying. Until now, Indonesia has lost forest of the original 72 per cent [World Resource Institute, 1997]Indonesia logging that is not restrained during tens of years and caused a contraction of the tropical forest produce.Rapid forest destruction period 1985-1997 was note down 1.6 million hectares per year, whereas in the period 1997-2000 to be 3.8 million hectares per year.This makes Indonesia one of the places with the highest level of damage to forests in the world. In Indonesia, based on the interpretation of Landsat imagery in 2000 there were 101.73 million hectares of forest and land damaged, of which 59.62 million hectares of plantation in the forest area. [MoF Penology Agency, 2003]In the 16-century to mid-18 th century, natural forests in Java are estimated at around 9 million hectares. At the end of the 1980s, veils of natural forest on Java only 0.97 million hectares, or 7 percent of the total broad Java. Currently, the closing of land on the island of Java by 4% live trees. Java since 1995 and have experienced water deficit of 32.3 billion cubic meters each year.

Function of forest is as reservoir the water will also be disturbed due to forest destruction that constantly. This will impact on the drought often occurs in the dry season and flooding and landslides in the rainy season. In the end, this will seriously impact on the economic condition in the community.Woods industry in Indonesia has a very high
production capacity compared to the availability of wood. industrialist timber logging uncontrollable and destructive, a planter of a very knowledgeable, and the mining areas of open forest. Meanwhile people be moved in forest management that resulted in people no longer have access to their forests. And this also worsened the condition of the corrupt government, where the forest is considered as a source of money and can be take out for personal and group interests.

Logging in Indonesia is uncontrollable has started since 1960s, which is known with the flood-hood, where people doing timber manually. Large-scale logging began in 1970. And permission to proceed with the issuance of a permit-forest plants in the industry in 1990, who finished land clearing. In addition, the forest is also diverted into the area of its large-scale clearing of forest also comprehensively, a resettlement area and also the area of urban development.In 1999, after the start of autonomy, the local government be sharing to the area of forest area in the form of rights of small scale. At the same time also increased the activity logging without a permit that is not restrained by the group that financed capitalist society (capitalist), which is protected by the government and security apparatus. Now let's save earth, save green earth.
