'Invisible' bacteria dupe the human immune system

I always have this fear that creating medicines against relatively harmless pathogens will cause them to evolve into more dangerous forms. I mean, these bacteria have coexisted - yes coexisted with humans for a very long time. It's hardly to their benefit to kill the host, but when we force them to evolve we are opening a Pandora's box of potential killer variants.

This is hardly an idle fear, given the myriad forms of drug resistant and more deadly versions of staph infections that constantly emerge in hospitals...

Haemophilus influenzae is not harmless, but yes there are many harmless ones targeted, especially the idiocy of adding antibiotics to anything is a dangerous and dumb practice. Just to make a bit more money corporations take advantage of average persons ignorance (since those antibiotics are not helpful in anyway) at the same time polluting the environment with toxic chemicals, which can very well prove deadly to many organisms including humans if they accumulate to high enough levels.
They also increase selective pressure on pathogens to develop better resistance to antibiotics.
I'm really concerned with the number of chemicals that humans dump into environment, the current assumption is that if for compound X there is no proof of harmful effects its ok to manufacture tons of it many of which will end up in world water supplies or soil. The truth is that most of those chemicals will be toxic to some organisms, the life is so diverse that there certainly is some organism who happens to be unlucky enough to have a key enzyme shaped in a way that will make it susceptible to inhibition by compound X.
Many of those compounds will also prove harmful to humans but it may take 100 years or more before we have the data to back it up, by then many people will die due to ignorance and greed.
