Your favorite cotton tee might make you feel all warm and fuzzy, but it’s secretly plotting to destroy the Earth. Growing cotton produces tons of toxic runoff, and in an effort to fight the effects of farming the fabric of our lives, Knowledge Cotton Fashion Apparel has launched The Earth Count, a new unisex T-shirt line made from 100% certified organic cotton. Across the front is “I Am Person [BLANK]” filled in with a unique number. Plug in that number at TheEarthcount.com to see how much chemical and pesticide waste your simple purchase has saved. Kind of nifty, even if the focus is a little egocentric. The shirts will be available in stores and online beginning on September 15th.
