A discussion on the alternatives to the clean water dilemma

Fortunately tactics effective at scaring the public do not work in the scientific community. Pages of the EPA response summarize nine reasons presented in the petition that allege, "Purposeful fluoridation of drinking water presents an unreasonable risk to human health from neurotoxicity. EPA denied the TSCA section 21 petition, primarily because EPA concluded that the petition has not set forth a scientifically defensible basis to conclude that any persons have suffered neurotoxic harm as a result of exposure to fluoride in the U. Examples include, "Although many human studies have been collated and reviewed in the Petition, for the reasons outlined previously - particularly study design and confounding factors - relationships between urine and serum fluoride internal doseswater fluoride concentration external doseand neurotoxic effects in humans have not been established.

He further claims that the immense slabs of broken crust, which he calls "hydroplates," undulated, heaved and slid thousands of miles in a matter of months or less, and then crashed into each other to form mountains within hours.

Compelling Evidence for Creation and the Flood, now in its 8th edition Brown, He provides updates and excerpts of large portions of his book at his Creationscience.

Brown indicates that he is "Director of the Center for Scientific Creation" in Arizona, which apparently consists of two people he and his wife. In the wake of such criticisms, Brown removed a few of the most glaring errors from his book and website, such as those regarding the "shrinking sun," "missing neutrinos, and a "Japanese plesiosaur" Kuban, ; however, he continues to promote many other dubious and unfounded claims.

Unless otherwise stated, any references to page numbers in this critique apply to the 8th edition of his book. This precludes any significant earthquakes, meteorite impacts, or fissures in the crust anywhere on entire earth, even though such phenomena are well evidenced throughout the geologic record.

However, one reason it is not circular is that meteorites and impact craters are known from Precambrian strata, which Brown and most other YECs view as pre-Flood rocks.

Moreover, the ages of these strata are derived from several independent dating methods discussed in further detail later.

Even without earthquakes or meteorite impacts, the only way a surface crust could cover a global expanse of water below it is if it were almost perfectly smooth, lacking any mountains even hills. Otherwise the crust would buckle, massively fracture, and release the subterranean waters Morton, a.

Since Brown accepts the presence of pre-Flood mountains which are mentioned in the BibleBrown evidently realized that he needed something to help support the crust. Thus, he proposes that on Days 2 and 3 of the "creation week" which he takes as literal solar daysthe granite crust "sagged down" deeply in places, all the way to the floor of the rock below the water chambers, forming supporting "pillars.

First, there is no empirical evidence for such pillars. Second, miles-thick granite plates would not "sag" and deform, especially in a matter of days, without extensive and massive cracking, which would immediately release the pressurized water.

Brown suggests the granite crust would act like "putty" while under pressure, allowing it to deform without much cracking, and that any cracks would self-seal before they reached the water chambers. However, granite is an extremely hard and crystalline type of rock, and does not deform to any significant degree without massive fracturing, except when near its melting point, and over long time periods Nelson, In contrast, Brown suggests the pillars formed in days, and if the Earth was hot enough to melt granite during the "creation week," it would only exacerbate the already immense heat problems discussed below, and kill all life on earth.

While this allows one facet of his model to better coincide with geologic data, it exacerbates the problems discussed above. First, it worsens the irregularities that would invite cracks in the crust.

Second, the greater thickness of the granite crust would make it even more difficult to deform severely and form the "pillars" without extensive cracking and earthquakes, immediately releasing the pressurized water below.

What Initiated the Flood? Even other YECs such as have noticed this inconsistency and its troubling theological implications. Oard notes that this would imply that God created the earth as a "ticking time bomb. Adding to the confusion, Brown suggests on p. Indeed, a few sentences later he suggests that because mankind sinned, human activities may have initiated the Flood by weakening the crust.

In any case, his suggestions about human activities seem to not only contradict each other, but also his initial claim that the Flood was due entirely to natural, geologic events, and his later assertion that the Flood was directly initiated by God. Good luck to anyone trying to sort all this out.

Appealing to supposed experiments with "supercritical water" SCWBrown claims the heat would be insignificant, but the calculations demonstrate that the heat would indeed be more than lethal.

Sharp calculated that the energy released in ejecting just the still-orbiting asteroids is the equivalent to approximately twenty trillion hydrogen bombs.

Sharp remarks, "The mind completely boggles how Noah and his family, together with his menagerie of animals and plants could have possibly survived all this in a large wooden boat!

Even YEC author Danny Faulkner of AIG demonstrated that the heat involved in the eruption phase alone would have been many times beyond lethal to all life on earth. In a video at his home page, and in the on-line draft of his 9th edition, Brown himself states that the energy released during the hydroplate eruptions would have exceeded trillion atomic bombs Brown, This makes it even more implausible that Noah and his cargo, or any macroscopic life on earth for that matter, would have survived the proposed hydroplate eruptions, to say nothing of the additional sources of massive heat and violence discussed below.

He further calculated that if only 0. Even if his proposed forces allowed that, they could not occur without huge amounts of friction, turbulence, and steam release, and condensation on Earth--all involving massive amounts of energy and heat left on Earth.mewish asad.

hellow sir if you dont mind i want to take help from you i am home economist done masters and now cant do the job due to knee accident i want to start buissness if i take 1 kg sodium luthral and half kg Nacl and a bucket of water it make a shampoo by mixing it is it correct way i want to support my family tganks sir and please .

In Chapter 4 of Listen To Your Gut, I write about the dangers of Teflon-coated (and other non-stick coated) pots and pans and give you all the data on why we shouldn’t use them..

Well, following is an interesting article from the New York Times, written by someone else who heard about the dangers of Teflon and set out to test a number of different pans . Rubbermaid's new Hygen clean water system turns dirty water into clean.

Rubbermaid Commercial Products has introduced the new Hygen Clean Water System, which features what the company believes is the first ever integrated water filter that generates cleaner water, cleaner mops and cleaner floors.

PROPOSED ACTION AND ALTERNATIVES INTRODUCTION This chapter describes the Proposed Action which would require a Department of the Army (DA) permit under Section of the Clean Water Act for the discharge of dredged or fill material into waters of the United States.

The Clean Water Act Section regulatory program provides that the Army Corps of Engineers evaluate permit applications for the discharge of dredged or fill material into waters of the U.S., including wetlands, in accordance with regulatory requirements of the Section (b)(1) Guidelines (Guidelines).

Nuclear power is an alternative energy source with the visage of being clean and reliable, but also dangerous. Nuclear power as an energy source emerged after , and is formed in a process called nuclear fission, in which a nucleus of an atom is split resulting in a large output of usable energy (World Nuclear Association).
