Organic cotton uses about 91 percent less water than some conventional estimates claim, but the honest picture is that it mainly cuts pesticides rather than thirst.
Know that organic cotton avoids synthetic pesticides and fertilizers, which is better for farmworkers and soil.
Do not assume organic always means low-water, because cotton of any kind remains a thirsty crop in dry regions.
When buying, look for organic plus recycled fibers, since a blend can lower the overall footprint more than the label alone.
