Контекст: Global production of wood amounts to 3.4 billion cubic meters a year, half of which is for woodwork and the other half for firewood. Working forests counts for 1% of the global economy and for 3% of all international commerce. Business transactions related to wood and paper are estimated at $200 billion a year. In 2005, forest products other than wood were valued at $18.5 billion. It is estimated that in developed countries alone, forests provide a living for about 600 million people. In developing countries, about 80% of what is removed from the forests is destined for use as an energy source. In other words, the wood is used primarily to cook food, while the forests in developed countries are used mainly to produce wood products and paper.
