That is one nasty looking water filter. Although it gives my shivers to see what that kind of grime could do to a person but I have seen worst here in Warsaw.
Chicken farms you say........... I was actually reading on chickens and how it is unprofitable for farm owners to keep them after a certain amount of time. Thus comes the feed that is genetically modified and on top of that infused with steroids for faster growth of the chicks. The possibility of this affecting the nearby water sources after a substantial amount of time is quite real.
Also - as you mention the problem of fluorides in water is even more severe and ever present.
I raised 6 of the infamous factory hybrid Cornish Cross chicken , which are the birds that have huge breast and are butcher weight within 6 to 8 weeks. The birds grew so fast they couldn't walk easily by the time they were 5 weeks old, they were prone to heat exhaustion, infection, heart disease, and deformed bones...
This is why Chicken factory farms need to feed the birds antibiotics and can't let them free range. The birds can't live past a year old and cannot mate because of their large breast and deformed legs caused by fast growth and unnatural weight.
The runoff from the farms is polluting our dirt as well. The manure from the chickens is full of chemicals is used as fertilizer by surrounding produce and agricultural farms..
I sometimes have to stop and think............ I know people don't really care much for spirituality and religion but one has to ask the hard question.
Let alone the fact that the animal has to suffer from the birth and to a degree that it cannot even complete it's life span. A few days ago I was arguing my case with another gentlemen, here on steemit. The point he put forward was that requirements of humanity are so great that not all standards can be maintained.
Forget the discussion at of food and talk about the most basic item of consumption, i.e. water. The fact that it is not even drinkable anymore should give a pause. Sure requirements of humanities are great - but are the great enough to raise an entire generation of sickly people because science has conclusively shown that long enough exposure will make are bodies adapt and sometimes not in a favorable fashion. I think to be lazy about where the food is coming from has more to do with laziness then anything else. Our diets are at mercy of corporate entities rather than the supposed environmental shortcomings of the planet.
(I would also like to state here that my belief is that humanity overestimates itself. We are but a speck in a scheme of bigger things. To think that a whole planet would fall short in providing for a species whose whole population(past and present) can be fitted inside one big city is a little egotistical.)
The idea of taking care of nature is not just of what we give back would be returned to us. It seems more of what we pass on would reach into the evolution thus changing the future.
Sorry! Went a little off tangent. Can't get the picture of those chicks not even able to walk properly off my mind.
