Water shortages and drought are having an impact on cotton production, causing price fluctuations and even a shortage in denim.

A pair of jeans uses 919 gallons of water during its life cycle, enough to fill 15 spa-size bathtubs. That includes the water that goes into irrigating the cotton crop, stitching the jeans together and washing them scores of times at home.

The company wants to reduce that number any way it can, and not just to project environmental responsibility. It fears that water shortages caused by climate change may jeopardize the company’s very existence in the coming decades by making cotton too expensive or scarce.

Although scientists are wary of linking specific extreme weather events to climate change, recent increases in floods and droughts are in line with patterns that experts have long projected would result from global warming.
