Male fish turning female in shocking numbers

One third of the male fish in British rivers are turning female, and roach in some rivers show up to 80% of male fish with female characteristics.

This shocking finding is probably due to human female hormones from birth control pills and horomone replacement therapy that drain into rivers through sewage systems.

Gender-bending problems have also been seen in ocean fish like cod and salmon in Britain and elsewhere.

Are transsexual fish a problem? Moral concerns aside, we need to make sure that similar things don't start happening to people. There is cause for concern that gender-bending chemicals are already harming people, but skeptics say "balderdash!"

Me, I'm heading for the organic aisle in my market, and avoiding fish from contaminated water.
