Bamboo is 100% naturally grown, without needing any pesticides or fertilizers .

Bamboo fibre is 100% biodegradable.

As the fastest growing plant in the world, bamboo grows to its maximum height in about 3 months and reaches maturity in 3-4 years. It spreads rapidly across large areas. Because of this, bamboo is known to improve soil quality in degraded and eroded areas of land.

As a grass, bamboo is cut, not uprooted, also helping soil stability. Bamboo also can grow on hill slopes where nothing else is viable.

The yield (i.e. the amount of product) you get from an acre of bamboo is 10 times greater than the yeld you get from cotton. In an age where land use is under enourmous pressure this is huge.

The water requirement for bamboo is minute, mainly just from what falls. As opposed to cotton, whose water requirement per shirt's-worth is huge.

If organic clothing made from bamboo becomes popular, it means more bamboo plantations, which means more photosynthesis and less greenhouse gas. "The greatest challenge facing mankind" would get just a little easier.
