While this is not surprising and questionably news, I am a little more worried about the years and years of synthetic, biologically active drugs in the water. Birth control hormones don't exactly just disappear after you swallow them, and I know that they and other classes of petroleum based drugs have shown hormonal activity not only in mammals, but amphibians, fish, and birds. Though a world with huge breasted marine mammals would be cool, I am more concerned about the chemicals other than coffee that are following the same pathways and reaching the entire world. Miles deep into the ocean, thousands of miles through the atmosphere, there is really no where on the planet that has not been affected in at least a minor way by the expansion of human industry.
