Organic cotton production rose 10% in 2015 and is expected to rise 15-20% in 2016. In just twelve months, the market value of organic cotton grew by 67% to over $15 Billion. With numbers like these, and large retailers committing to organic apparel as a large component of their product line, organic and eco apparel is no longer a niche industry. While organic cotton is driving the bulk of supply, growing search demand for hemp and bamboo is creating profitable online marketing opportunities targeting niche keywords.
