Chickens are fed Arsenic and Prozac

Yes - antibiotics are such a powerful tool but medics and industry are waisting it. It is like a sharp blade that gets blunt when it is used all too often. If you use it only when it is really needed, then it will last for a long time, but if you use it casually and without thinking every day on the slightest occasions, it will loose its edge soon and needs resharpening. With antibiotics sadly, the resharpening is not that easy and new antibiotics may be more harmful as older ones.
It totally makes sense to use them when a persons life or long term health is in peril, but to regularly feed them to animals as part of their diet or even to give them to people just because they may feel a little sick should not be a regular occurence.
