blue from indigo, a flowering plant (and you can still find high - end, indigo -
dyed selvedge
denim), but that natural process is pricy, and now 90 percent of
denim produced in China uses cheap, synthetic
dyes made from coal tar, sulfur, and other toxic chemicals.
It sucks up around 1,500 gallons of water for just one pair of jeans, and every year, there are over 2 billion pairs of jeans produced globally — and when
denim is rinsed, it leaves several tons of nasty, toxic
blue dye that goes right back into our water ways.
