Bamboo is a self-regenerating raw material with a continuous production of new shoots. It does not die when it is cut down, it can replenish itself.
Ordinary trees have to be cultivated from seedlings, and need to grow for several decades to produce timber. The trees are cut and them new trees have to be planted again as seedlings to create a new forest. Bamboo grows into a forest by reproducing itself and continuously provides timber. It is a surprising resource for the future, one that contributes to global econimic growth as a green alternative to traditional timber.
