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.

The Causes of Forest Deforestation

Forest DeforestationDeforestation in Indonesia is mostly a result of a political and economic system that corrupt, that the natural resources, particularly forests, as a source of income that can be exploited for political and personal gain. The growth of processing industries and wood plantations in Indonesia is proven profitable for many years, and the benefits used by the Soeharto regime as a means to control and give the friends, family and potential partners. For more than 30 years, the country is dramatically increasing production of forest products and the results of the land planted in the previous form of the forest. Today Indonesia is the major producer of wood rounded, timber saw, plywood, pulp and paper, in addition to some of the results, such as palm oil, rubber and cocoa economic growth is achieved without considering the sustainable management of forests or the rights of local residents.
For now, the causes of deforestation the forest complex. Lack of law enforcement that occurred at this time serious condition of damage to forests and directly impact on the habitat for orangutans reduced significantly. The cause of the damage can be expressed as follows.

1. Rights of forest control
More than half of the Indonesian forest area allocated to timber production system based on fells select. Many companies that violate (HPH) patterns traditional rights of ownership or land use rights. Lack of supervision and accountability of the company means that the supervision of forest management and is very weak, long run, many forest products that have been exploited excessive. According to the classification of government, at the moment almost 30 percent of (HPH )concessions that have been surveyed, included in category "most degradation already." (HPH) concession areas that experienced a decrease in the quality degradation to be easier under the threshold limit of productivity, which enables the planter to apply for permission for forest conversion. If this application is approved, then the forest will be fells out and turned into forest plantations or industrial plants.

2. Plantation industry forest
Forest plantation industry has promoted a massive subsidy and given as a way to provide a supply of wood for the pulp industry is growing rapidly in Indonesia, but how this will bring pressure on natural forests. Nearly 9 million ha of land, most of the natural forest, has been allocated for the development of forest industry plants. Land is fells This possibility has been exhausted or in the near future to be fell will given out. However, only about 2 million ha have been planted that, while the remaining 7 million hectares of land into a desolate and not productive.


3.Plantation
Development of spring crops, especially oil palm plantation, is another cause of deforestation. Nearly 7 million ha of forest have been approved to convert into plantations until the end of 1997, and this forest has been almost to be fell be exhausted. But the land is actually converted into oil palm plantations since 1985, only 2.6 million ha, while new plantations of other crops for the broadest possible reach 1-1,5 million ha. The remaining area of 3 million ha of forest land that were previously present in squalor. Many of the same company, which operates concessions (HPH), also has a plantation. And corrupt relationships developed, where the employers to apply for permission to build plantations, forest and cut out the wood produced primarily for the pulp, and then moved again, while the land that has been opened be abandoned

4.Illegal logging
Illegal logging is the practice of directly on the tree in the forest area of the country illegally. View from the types of activities, the scope of illegal logging include:

  • logging plan, covering all or part of the activities of access to forests in the country, bringing the tools and infrastructure facilities to perform logging of trees with the goal of the illegal exploitation of timber.
  • logging of trees in the meaning actually for the purpose of the illegal exploitation of timber.

Production of wood that came from (HPH) concessions, industrial forest plantation forest conversion and overall provide less than half the raw materials needed by the wood processing industry of wood in Indonesia. Wood is imported is relatively small, and filled lack it from illegal logging. Theft of wood in a very large scale and which is now organized riot in Indonesia; annually between 50-70 percent of the supply of timber for forest products industry be fell illegal. Area total forest lost illegal logging because it is not known, but a former Director General of Forest, Ministry of Forestry, Titus Sarijanto, recently stated that timber theft and illegal logging has destroyed about 10 million ha of Indonesian forests.

5.Convention Land
The role of traditional small-scale agriculture, compared with the other causes of deforestation, is a subject of great controversy. There are no accurate estimates are available on the wide forest that are opened by small scale farmers since 1985, but an estimate that can be trusted in 1990 states that move the tiller may be responsible for about 20 percent loss of forest. This data can be translated as land clearing about 4 million ha between 1985 until 1997.

6. Transmigration Program
Transmigration that lasted from 1960 until 1999, the population of the island of Java which has a compact to other islands. This program is estimated by the Ministry of Forestry to open forest land, almost 2 million ha during the entire period. In addition, small farmers and small scale investors opportunist who also share the causes of deforestation as land to build their plant crops, especially palm oil and cocoa, which opened in the forest with plantation operations logging and the scale it greater. Recently, transmigration "spontaneous" increase, because people move to a new place to search for economic opportunity is greater, or to avoid the disruption of social and ethnic violence. Estimation that can be trusted on forest area opened by the migrants in the national scale has not been made.


7. Forest Fire
Burning deliberately by plantation owners to open a large-scale land, and by the local people to protest or plantation operations (HPH) caused a fire that big is not restrained, and the wide intensity it unprecedented. More than 5 million ha of forest burned in 1994 and 4.6 million ha of other forests burned in the year 1997-98. Some of this land to grow back into bush, some used by small scale farmers, but little systematic effort made to restore the forest or the imprisonment of productive agriculture.

In the natural conditions, land, peat moss is not flammable because it does resemble a spoons, that absorb and hold water so that the maximum in the wet season and dry season there is no difference between the extreme conditions. However, if the land is peat moss has started be disturbed a result of conversion of land or the making of canals, the balance ecology will disrupted. In the dry season, land is very dry turf will until a certain depth and flammable. Turf containing fuel (the rest of the plant) to below the surface, so the turf fire in the area under vine in the land surface and the slow and difficult to detect, and cause thick smoke. Turf fire in the area can be difficult to be quenched, so take long time (many months). And, the new total could die after the rain intensified. let's save earth, save green earth.

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.
