Wood is a hard, fibrous tissue found in many trees. It has been used for hundreds of thousands of years for both fuel and as a construction material. It is an organic material, a natural composite of cellulose fibers (which are strong in tension) embedded in a matrix of lignin which resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in tree roots or in other plants such as shrubs.[citation needed] In a living tree it performs a support function, enabling woody plants to grow large or to stand up for themselves. It also mediates the transfer of water and nutrients to the leaves and other growing tissues. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber.
The earth contains about one trillion tonnes of wood, which grows at a rate of 10 billion tonnes per year. 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.

Wouldn't you think that
I'd have it all figured out by now
That I'd know exactly what I'm dong
Wouldn't you think that I'd have a key
To open every melody and sing
Like it is all here at my feet
Wouldn't you think that
I'd have a life hanging on my wall
So I could prove that I'm alive
But these are just things I've been given
For a plastic way of living
And I'm not sure if that really is my style
The second hand it rolls on by
It never looks back to wait for mine
And if I fall any harder this time
If I dig any deeper Lord what will I find
Well you can buy my life on radio
And order me by mail
But not everything about me is for sale
No not everything about me is for sale
Wouldn't you think that
I'd have the strength to carry anything
And I could buy myself
A brand new set of hands
But sometimes like the others
I just ran away take cover
And I swear that no one really understands
The second hand that rolls on by
