I live in the catchment area for the Great Barrier Reef. Plastic microfibers from washing clothes are a distinct threat to the Reef. I've been picking up bamboo clothes as I can afford them. Most comfortable stuff ever. I even pick up some at the local thrift shop! Note that clothes here need to protect from sun, wick away sweat and discourage mosquitoes.
