The single animal study of pineal function indicates that fluoride exposure results in altered melatonin production and altered timing of sexual maturity. Whether fluoride affects pineal function in humans remains to be demonstrated. The two studies of menarcheal age in humans show the possibility of earlier menarche in some individuals exposed to fluoride, but no definitive statement can be made. Recent information on the role of the pineal organ in humans suggests that any agent that affects pineal function could affect human health in a variety of ways, including effects on sexual maturation, calcium metabolism, parathyroid function, postmenopausal osteoporosis, cancer, and psychiatric disease.

“In conclusion, the human pineal gland contains the highest concentration of fluoride in the body. Fluoride is associated with depressed pineal melatonin synthesis by prepubertal gerbils and an accelerated onset of sexual maturation in the female gerbil. The results strengthen the hypothesis that the pineal has a role in the timing of the onset of puberty. Whether or not fluoride interferes with pineal function in humans requires further investigation.”

The Pond Sand Filter is a device that takes pond water and makes it safe to drink by filtering out bacteria that is harmful to human beings. It’s a proven technology but it has its limitations.

Pros
- No fossil fuels, solar power, or electricity required
- Nearly effortless to pump
- Purifies enough water everyday to provide hundreds of families clean & safe drinking water
- The water purified is safe enough to be used for cooking (low or no iron in the water)

Cons
- Limited lifespan (minimum two years), needs to be replaced eventually like any filter
- Increased complexity vs. the deep tube well (Murphy’s Law – more can go wrong)
- More vulnerable to vandalism than a deep-tube well (can unscrew and steal the faucets, etc)

The person in the video is a local villager. She’s not an expert in pond sand filters – but I wanted to see what the local perception of Pond Sand Filters are.
