Please don't drink too much beer. Soon there will be tests done on why birds fly into windows. They will find that these birds were FWI (Flying while intoxicated). The source will also be human urinary excretions.
Then we will be taxed for each time we flush because that will be the only way to "save" birds.
Seriously, I find that the environment is being messed up by Pharmacutical companies. If they stopped creating new useless drugs then our earth would be "greener". OTOH, have there been studies about how many vitamins are in our water?
Thankfully I'm a little older and wiser and have found that I can fool myself into enjoying near-beer (non-alcoholic). :)
Vitamins in water are a little less problematic than hormone and endocrine disruptors. If you take a multivitamin for instance, your body will eliminate a majority of it because it can't be absorbed at one time. If you drink 8 glasses of water throughout the day, spread out, whatever is in that water will affect you to some extent. Iron in drinking water is very common and contributes to high blood pressure in many people. I'd personally rather have that than than chemicals known to cause androgyny in animals.
