I grow several species of bamboo in my garden, and I am impressed by how well this palnt is adapted to its environment. If you look at a bamboo rod/cane, you will see that there is a strengthening joint every 6.6 inches (on phylostachys aureus). If you look at the wall thickness, and test the strenght on the rod under a bending load, you will find that the structure is almost perfectly optimal? It took aeronautical engineers decades to design and optimum wing.fuselage structure…how did the lowly bamboo plant mutate itself into a perfect load-bearing design like this?
Makes you wonder…is God a civil engineer? What CAD program does he use? 
Well it took evolution a lot longer.
In the old geek joke, God must be a civil engineer. Who else would run a waste disposal port right next to a recreation facility?
Bamboo makes an excellent reinforcement for cement projects. In the Thomas Edison museum in Ft Meyers, Florida, there is a swimming pool that was built with cement and bamboo. It has never had a crack in it. Bamboo makes better reinforcement than steel rods or fencing. Believe it or not.
