Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic material. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper.

Facts
As of 2005, the growing stock of forests worldwide was about 434 billion cubic meters, 47% of which was commercial. As an abundant, carbon-neutral renewable resource, woody materials have been of intense interest as a source of renewable energy. In 1991 approximately 3.5 billion cubic meters of wood were harvested. Dominant uses were for furniture and building construction.
