I didn’t know. Nor you According to the Organic Trade Association, roughly one third of a pound of environmentally harmful chemicals, pesticides and fertilizers are typically used to grow enough cotton to produce one of your t-shirts. Wow! Cotton is one of the most chemically treated crops on the planet! Instead, Bamboo holds the promise of a sustainable, cost effective alternative to the wide spread clear-cutting of the planet’s old growth forests and is in addition the most sustainable textile material available today! Bamboo, classified as a grass, thrives in many different climates without the use of environmentally harmful pesticides and fertilizers or irrigation. It has an extensive root system that continually sends up new shoots, naturally replenishing itself. No old growth forests are touched – No trees are cut! Conclusion: wear Bamboo. If you want to see a nice collection of couture made out of bamboo (sorry, women only), go to Chopper Couture.
