Is Bamboo an Earth Friendly or "Green" Yarn?

I'm looking forward to spring. I am really ready for this winter to be over!
Every once in a while, we have a somewhat nice day and I venture outside.
Several years ago, we planted bamboo, and it's getting to the stage where it could be harvested without damaging the planting.
And, I've been reading a lot about Bamboo Yarn. So, I decided to look up what it takes to make bamboo into yarn. Might come in handy if I'm ever on Survivor, right?
Anyway, I found some pretty scary stuff out there when they try to describe the process. And, it seems to be a pretty industrially intensive process. Something requiring some pretty exotic sounding chemicals and some expensive sounding machines. I'll keep looking though.
Let me know if you know how this really happens.
