There is a storm in the tea cup that is New Zealand, about the environmental friendliness of bamboo fiber. It started with an article in our much respected Consumer magazine; you can buy the article here if you wish. I understand the article dealt with the manufacturing process of bamboo fiber, comparing it to cotton and rayon. A short comment in one of the fiber-related newsletters I subscribe to, summed up the article, saying: "So, bamboo is rayon."
I need to get a hold of this magazine and read it because I know nothing of the subject, but I know someone who knows a great deal, and she has a totally different opinion to the article. I hope to post her view here in the near future.
