Overview bbq catering of forest land is wooded forests of natural beauty and bio-diversity which is in itself a source of natural task, and in the eyes of the forest rights is a place for hiking and a source of construction materials and construction. Forests bbq catering are natural sources is a renewable if managed properly. But the human history of the destruction of forests through incineration or removed for agricultural purposes and others. Forests are important from an environmental perspective, and is important bbq catering in the environmental impact on the climate, bbq catering the existence of forests in the region makes it more moderate temperatures and more moisture from the free areas of the forest. Also contain forest on the genetic origins of plants, and are considered bbq catering centers of biodiversity and is home to many animals, especially rare ones, such as insects, bright and wild animals and birds, as well as its process of photosynthesis as it works to absorb carbon dioxide from the air and give oxygen, as well as working on the absorption large amounts of various air pollutants from the air. Cutting off the trees in these forests threatens not only vegetation, but the human and animals that live in them, too. The area of forest in the world, according to estimates of the Food and Agriculture Organization (FAO) in 1999 to about 3454 million hectares and occupy about 6.26% of the land area. The distribution of this space between the developed countries, which has an area of 1 493 million hectares, and the developing countries, which owns about 1961 million hectares, and so there is the ratio most of the forests in developing countries, 77.56%, while the developed countries bbq catering Vnsptha 23.43% The percentage distribution of forest between countries and continents, come Latin America and the Caribbean at the forefront of the world, as it has 950 million hectares, while the rest of the continents and countries of the world will vary in size and the ratio between them. Studies suggest FAO that 60% of the world's forests are located in 7 countries: the Russian Federation, Brazil, Canada, the United States, China, Indonesia and Zaire, and the cultivation of forests at the moment is increasing and attention, especially since 1980 and until the present time. In order to be woods lung real sound and you turn diversity to the fullest must deal with air inhalation and exhalation and other gasses, and this is what the forest really, it was made clear measurements that square kilometers and is one of the tropical jungle called in one day about ten tons of oxygen, and we can imagine the extent of the purity of the atmosphere in tropical forest areas where called per square kilometer is about 3650 tons of oxygen per year. The forests in the temperate zones range from the amount of oxygen released to the atmosphere from 1 to 3 tons per day of oxygen, though these numbers seem small compared with the tropical jungle. But the positive environmental impact that leave the forest does not depend on the amount of oxygen released to the atmosphere when compared to the jungle areas of grazing, for example, or buoys plant in ocean water or areas of cultivation of field crops, bbq catering but added forest advantage of low temperatures in its biosphere, which gives the work This lung brilliant third dimension is physically and biologically absorb carbon and release oxygen gas, and this dimension makes forests more effective environmental and makes millions of people are turning to it in summer and winter to inhale fresh air. Retardation phenomenon greenhouses behind floods and disasters and acid rain and dust and whirlwinds of dust and multiple environmental disasters. For the trees, bbq catering played a major role in warding off the dangers bbq catering of this phenomenon, it is known that the vegetation in general and trees in particular advantage of the ability of a large deposition of dust and the portions were suspended bbq catering in the air on their leaves, studies indicated that the amount of dust accumulated around the trunks of large trees of more than 5 to 10 times amount deposited in non-forested lands, and deposited about nine tons on the trunks of trees per hectare of forest thereby reducing the proportion of dust about 30 to 40% in the atmosphere bbq catering from the woods nearby fields. This is due to the large area of flat paper (Lifearea), which ranges between 50 to 150 thousand square meters / ha. Field observations also indicated that some species are better able to dust deposition. Research showed deposition of about 5.2 tons of dust / ha / year on the birch trees, and 30 tons / ha / year on the cypress trees, and 50 tons / ha / year on the pine trees, and more than 50 tonnes / ha / year in the forest of beech dense ( 1994 FAO). The role of trees in warding off the dangers bbq catering of trees gases play an important role in purifying the atmosphere of the cities of carbon dioxide and some other gases, with the following role of trees in warding off the dangers of gases: The per hectare bbq catering of forest absorbs Ghaba
