Yikes. I had read about the pollution there, but that photo is NASTY.

I sailed an Opti regatta in Porto Alegre many years ago, totally different area and totally different time, but all they warned us about back then was alligators (or crocs, can't remember and not that I really knew the difference at 12 years old). I wonder what it's like there now.. Youth is so wasted on the young.
