In part it's about some of our most polluted rivers such as in Xintang, China; Yamuna, Delhi, India; Dhaka, Bangladesh; Citarum, Jakarta, Indonesia. Normally we think of sewage, plastics, industrial waste, but this adds clothing leather/textile manufacturing & how much it contributes to the morass. Even with what we wear, whether at work or casually, it gives more support to the KISS ethos of minimalism in life - wear less; use recycled more. My main concern w/this doc was the reliance upon subjective evaluation of the harm - looks bad, smells bad. The producers should have arranged to have samples taken when visiting each site & have them analyzed as to source chemical composition & quantity. Such objectivity substantiates action against the offenders.
