Ok, so we can rule out some influencer shit going on that I had in mind.
Still... perhaps it is because we don't have any bamboo around were l live, as I still don't get the "why".
Is it easy to carve? Some eastern tradition? I would never even consider it, also as bamboo doesn't even look like a good place to carve something, not to speak of being the garden part of a freakin' temple.
Or is it because bamboo is generally seen more as a fast-growing throw-away item?
"Broken window theory".
Yes, was also thinking along that line.
That would also mean that the green bands covering the stuff up are a sensible measure.
