It means, all our super high tech modern wear finally poisons our drinking water. And the most sporty young cool dressed guys are the worst polluters. One more reason to stay with natural fabrics.
Industry always tries to convince us that their high tech stuff is superior. Honestly, after buying a lot of it, I doubt that's true. All the artificial clothes smell quickly and they are not warm at all. I am switching back to cotton, wool, real leather shoes and (for the winter) down: This all feels great (but needs more attention and care).
