Forests are one source of life, which produces elements of air, water elements, and soil. The point here is that these three elements have a close relationship with the forest. The air element will be filtered to become clean air. Water element will be accommodated by leaves so as not to directly seep into the ground. And the elements of the soil will be stronger with the extension of the roots of trees in the forest.
With the preservation of the forest, the natural ecosystem will be balanced. The living beings that surround it will live with sufficiency, so the cycle of the food chain will not be cut off. From the economic side of Indonesia will benefit, by having a beautiful forest, of course, this will attract foreign tourists. With these conditions will certainly be a source of significant foreign exchange.
