Bamboo scaffolding

TreeHugger:

The short version: because [bamboo] grows so quickly, the root system isn't damaged by harvesting and it's so plentiful -- "For a lumber harvester, the yield can be 25 times what you'd get from regular ol' trees" -- growing it is really green,

This reminds me the scaffolding in HongKong. Here are some pictures I found in flickr:

You would have noticed that these structures are used to scaffold skyscrapers as well as odd jobs in renovation. One of two construction workers (or they are highly skilled bamboo scaffolding experts) can erect a lot in a single day. It is even faster to dissemble!
