Nice thought but from what I've read, the process of making cloth from bamboo would deplete more resources then replanting of the cotton. But everyone would rush to buy bamboo fabric just because it is labeled 'green'. Then the cotton industry would die back. When the bamboo hype becomes reality of what is being lost, then the cotton growers will be almost non existent. I do not support most 'green' products or methods until it's proven to save more then it looses.
