Na organic material, a natural composite of cellulose fibers (wey dey strong for tension) wey dey inside matrix of lignin wey dey resist compression. Wood sometimes dey defined as only the secondary xylem for the stems of trees, or e fit dey defined more broadly to include the same type of tissue elsewhere like for the roots of trees or shrubs. Inside living tree, e dey perform support function, wey dey enable woody plants to grow large or to stand up by themselves. E still dey carry water and nutrients between the leaves, other growing tissues, and the roots. Wood fit still refer to other plant materials wey get similar properties, and to material wey dem engineer from wood, or wood chips or fiber.

The Earth get about 434 billion cubic meters of growing stock forest, 47% of which dey commercial. As an abundant, carbon-neutral renewable resource, woody materials don dey of intense interest as a source of renewable energy. For 1991, approximately 3.5 cubic kilometers of wood dey harvested. Dominant uses na for furniture and building construction.

Answer the following questions:
1. How much wood was harvested in 1991?
2. Why?
3. How many meters of forest are there on our planet?
4. How much of that is available commercially?
5. Can this be renewed?
6. Is it rare?
7. How long has it been used in construction?
8. What is it's other main use?
9. What is it a composite of?
10. Are they weak?
