137 Animal studies in the 1990s by researcher Phyllis Mullenix, at the Harvard-affiliated Forsyth Research Institute, showed that rats exposed to fluoride in the womb were much more likely to behave in a hyperactive manner later in life. This could be due to direct damage or alteration to the development of the brain. (Mullenix's adviser told her she was "jeopardizing the financial support" of her institution by "going against what dentists and everybody have been publishing for fifty years, that [fluoride] is safe and effective," and she was fired shortly after one of her seminal papers was accepted for publication,according to Grandjean and a book by investigative journalist Christopher Bryson called The Fluoride Deception.)
Multiple studies also suggest that kids with moderate and severe fluorosis—a staining and occasional mottling of the teeth caused by fluoride—score lower on measures of cognitive skills and IQ. According to a 2010 CDC report, a total of 41 percent of American youths ages 12 to 15 had some form of fluorosis. Another study showed structural abnormalities in aborted fetuses from women in an area of China with high naturally occurring levels of fluoride.
There have also been about 40 studies showing that children born in areas home to water with elevated levels of this chemical (higher than the concentrations used in U.S. water fluoridation) have lower-than-normal IQs. Grandjean and colleagues reviewed 27 such studies that were available in 2012, concluding that all but one of them showed a significant link; children in high fluoride areas had IQs that were, on average, seven points below those of children from areas with low concentrations of the substance.
California continues to suffer through a fourth year of water shortages, bordered by the largest body of water on earth. The crisis has encouraged residents to once again wonder if the Pacific Ocean is the answer to the state's water woes. Some are pushing for additional desalination plants like those used in water-starved Israel and Australia to convert ocean water into unlimited fresh water. Coastal Santa Barbara turned to desalination during a devastating five-year drought in the late 1980s, but by the time a new plant was ready for operation in 1992, heavy rains had returned. The $35 million facility ran for a few weeks before being shuttered. That's because the desalination process is not only potentially harmful to marine life, but removing salt by pushing salt water through membranes takes far more energy than simply pulling fresh water from inland sources. All that energy use is not only counter to the state's push for lower emissions, but it only seems economical during the worst of a drought. As Santa Barbara reactivates the plant this summer, water bills in the area are expected to increase by 40 percent.
Since California will be using desalination, they will need an Alkaline Water Machine to return the minerals to their water
Compared to local freshwater sources, desalination is certainly energy expensive. But it's only slightly more costly than other options available during drought conditions. That's why Santa Barbara is spending another $40 million to reopen its plant, and why 17 others are in the works along the state's coast. In Carlsbad, California, Poseidon Water is opening a $1 billion plant that will be the largest in the U.S. when it is completed in the fall. In a recent Wall Street Journal article, CEO Carlos Riva defended desalination plants against those that worry that they represent a step backward in the state's efforts to reduce carbon emissions, pointing out that the plant will "use less energy than one of the data center that are being built, and nobody claims that they are somehow immoral." According to the Natural Resources Defense Council, data centers are expected to consume 140 billion kilowatt hours of electricity a year by 2020—the output of 34 large coal power plants. According to the Pacific Institute, the Carlsbad plant will take 750 megawatt hours per day, so more than 500 equivalent plants would have to be constructed to match the energy cost of our Facebook and Google habits... 324
