Welcome To My Small Site For Big Forest.

Importance of forests

Forests draw their importance from the products and services they supply. Wood- based products make a considrable contribution to the world economy amounting to some 2% of global gross domestic product and contributing to basic needs for energy and for material inputs to modern living inconstruction, furniture, communications and packaging. Some non- wood products of the forest are of commercial importance, but many more are non- marketed goods which are used by rural and subsistence communities and are essential to those economies. Services range from the conservation of soil and water and biological diversity, to the modulation of  the carbon cycle and the amelioration of microclimate. Forests also provide landscapes to meet the aesthetic and spiritual needs of human beings. Forests are a part of the heritage of peoples. The importance of forests, in these production and services functions, lies in their great extent, covering  as they do somewhat more than one fourth of the world's land area.
