Covid-19 “Airborne” Confusion Clarified

Truth about “Airborne” Covid-19

IMPORTANT: “Airborne” confusion: Covid-19 is only “airborne” as droplets that quickly fall to surfaces.

Covid-19 is NOT “airborne” as an aerosol that hangs and drifts freely in the air for longer periods like flu.

If Covid-19 was like flu, your mask would offer very little protection. The virus could enter through your eyes.  Social distancing would be meaningless because the virus would float freely over greater distances and for longer times.

The best way to avoid Covid-19 is by avoiding sick people, social distancing, wearing masks in public and cleaning surfaces frequently, including your hands.  Also remember to avoid touching your face, nose, mouth or eyes. Once your hands have touched anything that could be contaminated, virus could be transferred to anything including your cell phone, wallet, steering wheel, child, dog, etc and be picked up by you or others later.

Straightening your mask with contaminated hands may transfer the virus to your face, nose, eyes.  Wearing a mask improperly or reusing it without washing it could be worse than not wearing it at all.

Gloves are not recommended. Wearing gloves only protects your hands, not your face, etc. from virus picked up on the outside of contaminated gloves.  Covid-19 virus can live on surfaces for several days, depending on the material. so frequent use of  hand sanitizers, disinfectant wipes and sprays are recommended.

 

The Truth about AIDS in Africa

Are most cases of HIV/AIDS in Africa really misdiagnosed endemic diseases?

The Claims: HIV/AIDS from unsafe heterosexual contact is rampant in Africa. Many children are left as orphans because both parents have died from AIDS.

The Truth:  While HIV/AIDS is undoubtedly present in Africa and other destitute areas, there are problems with its reported transmission, diagnosis and treatment.  HIV infections in the developed world occurs almost exclusively among homosexual males and IV drug users who share needles with infected people, and heterosexual transmission is rare.  In Africa, half of those diagnosed with HIV and HIV/AIDS are heterosexual women, so there must be other mitigating circumstances.  It is possible that actual infections are acquired through non-sterile injections in contraceptive clinics.  This could help to explain why HIV in Africa is diagnosed equally among men and heterosexual women.  It is very likely that HIV and HIV/AIDS are over diagnosed in Africa and other poverty stricken areas of the world with or without actual HIV testing.  Many cases of AIDS in Africa may have little or no connection to the HIV virus or indiscriminate sexual practices.  Those that are malnourished or have chronic diseases such as TB or malaria naturally have compromised immune systems, i.e. Acquired Immune Deficiency Syndrome, AIDS, from these conditions without carrying the actual Human Immunodeficiency Virus (HIV).

Because of poor healthcare facilities and abilities, HIV/AIDS may be diagnosed based on symptoms without HIV testing in many rural and isolated areas.  In other areas, where actual testing for HIV antibodies is done, a high incidence of false positives is likely to occur.  This is due to the poor specificity of the test and reaction with antibodies from other diseases and conditions.  Most of those diagnosed with HIV/AIDS, whether tested or untested for HIV, have been assumed to have full blown HIV/AIDS through disparate symptoms recognized by the UN WHO including fever, headache, rash, sore throat, swollen lymph nodes, weight loss, chronic diarrhea or cough, all of which can be caused by many common parasites or infectious diseases as well as severe illnesses such as malaria and tuberculosis (TB). UN WHO has named TB as a leading indicator of HIV/AIDS and lists TB as causing 2/3 of HIV/AIDS deaths. HIV/AIDS itself does not cause death; it opens the way for other diseases that kill people. Reporting TB deaths as HIV/AIDS deaths without confirmation of HIV bolsters the statistics, as does reporting orphans as AIDS orphans.  At this time it is impossible to know how prevalent over diagnosis is in Africa and other poor areas.

Over diagnosis of HIV and HIV/AIDS, when promoted by the international media, paints a picture of Africa that packs a triple whammy for AIDS advocates and international population control governmental and nongovernmental organizations. First, it excuses high death rates and failure to treat endemic diseases; secondly, it incentivizes HIV/AIDS research funding in developed countries by falsely declaring AIDS a heterosexual pandemic; thirdly it has the potential for vindicating population control programs in the minds of potential donors by creating a false picture of rampant immorality and promiscuity. As a bonus, it also encourages the use of condoms that furthers population control agendas.

HIV facts and questions:

HIV causes AIDS: Unlike those who deny that HIV causes AIDS or that it even exists, I do not deny that HIV causes AIDS or that HIV exists. I do question some of the current statistics, testing and treatment options.  Because it is politically incorrect to question the UN WHO recommended practices and conclusions, those who question the status quo will undoubtedly be accused of denialism by AIDS advocates in order to conflate, confuse, discredit and silence anyone daring to question the efficacy of the current testing and treatment methods, even when it might lead to better understanding and improved protocols.

Non-HIV AIDS:  TB, Malaria, dysentery and other serious chronic diseases cause a more common form of Acquired Immune Deficiency Syndrome, AIDS, that has no connection to HIV/AIDS or sexually indiscriminate behavior.   It is well known that anyone who is chronically ill and/ or malnourished naturally has a compromised immune system.  Other opportunistic diseases are easily acquired by persons whose immune systems are compromised. By labeling these non-HIV AIDS cases as HIV/AIDS, it can be an excuse for not treating the underlying conditions.

Unfortunately, for USAID, UN WHO and activist NGOs or agencies that provide aid to poor countries, because their emphasis is on required or coerced population control and not on treating disease, many clinics do not have the basic medicines, equipment or facilities to treat endemic diseases, but have store rooms filled with birth control drugs, condoms and other birth control and abortion materials and equipment. This is a human tragedy and a crime against humanity that must be stopped. It is unconscionable that Western aid not be heavily weighted toward supplying medicines and equipment for prevention and treatment of endemic diseases.

Recommendation: In both HIV/AIDS and non-HIV AIDS, treatment should always begin with addressing the presenting diseases and malnutrition. Once the patient is stabilized then HIV/AIDS treatment can begin, but only after further confirmation of the original diagnosis of HIV/AIDS.  HIV/AIDS treatment drugs further compromise the immune system so that treatment of weakened, disease ravaged patients and those with non-HIV AIDS using these drugs may do more harm than good.

International aid organizations should be encouraged or required to reverse their decades old practice of oversupplying population control materials and under-supplying needed medicines, facilities, equipment and supplies to treat endemic diseases.

Demographic Shift: HIV/AIDS in developed countries is confined almost exclusively among homosexual men and IV drug users who share needles with HIV infected people. The expected pandemic in developed countries never materialized. According to official statistics, Sub-Saharan Africa accounts for 2/3 of the HIV incidence in the world, with Southern Africa, (South Africa and Botswana), accounting for most of that. 15 to 25% of the South African population has been diagnosed with HIV or HIV/AIDS. More than half of the HIV positive people in South Africa are heterosexual women. Heterosexual contact is blamed for causing the spread of HIV, but in other countries heterosexual transmission is very rare. Unless the HIV virus has mutated, this theory of frequent heterosexual transmission cannot be valid and other mitigating factors must be considered.

Shared needles as a possible source:  One theory is that the reuse of hypodermic needles for injected birth control drugs is responsible for the spread of HIV, and, if true, could account for the higher incidence in women in Africa and other poor countries where injected birth control is required or advocated.  Injectable birth control drugs such as Depo Provera that must be reinjected every 3 months are sometimes administered in a clinic, but more often the drug and the syringes are given to patients for administration at home.  Because viruses do not live very long on surfaces outside the body, HIV could not be transferred unless an HIV infected person has used the needle just prior to reuse by a second person for birth control. This could only happen in a clinic where multiple women are injected one after another without proper sterilization of needles.

How are these in-home administered reused needles causing HIV/AIDS without an immediate HIV contamination source in each case? It is more likely that in-home injections with improperly sterilized needles would transfer opportunistic bacterial infections such as staph and strep.  The whole idea of giving hypodermic syringes to uneducated people is ludicrous; it is the worst of the birth control methods, and the best way to spread more disease and misery.  Poor women with little or no concept of microbial infective agents are unlikely to discard or destroy needles even if the package instructions say to discard after use.

Recommendation:  If this form of birth control must be injected every 3 months, it should only be done by a professional in a clinic with properly sterilized or disposable needles.  If birth control is desired, a better alternative would be insertion of an IUD, Intrauterine Device, which does not require regular follow up treatments.

Could Depo-Provera make women more susceptible to HIV infection? According to this theory, the active ingredient in Depo-Provera, (Depo-medroxyprogesterone acetate, aka DMPA), may chemically predispose at risk women to acquiring HIV through sexual contact with infected men, through thinning of vaginal epithelial cells and immunosuppression. Three recent meta-studies[1] show a statistically significant link between use of the drug and incidence of HIV in at risk women. The link to HIV transmission was not established statistically for use of either oral contraceptives or another injectable contraceptive drug, NET-EN, (norethisterone enanthate), in these studies.

Clinical Diagnosis without HIV testing: In rural poor areas of Africa HIV/AIDS may be diagnosed without HIV testing by the clinical indicators listed by WHO such as fever, headache, rash, sore throat, swollen lymph nodes, weight loss, chronic diarrhea or cough. These symptoms may also be caused by endemic diseases such as TB, malaria and other insect borne diseases, dysentery and other water borne diseases, parasites and malnutrition. WHO considers TB to be a leading indicator of HIV/AIDS. Some people diagnosed without HIV testing may instead have non-HIV AIDS caused by these endemic diseases.

Diagnosis with HIV testing: Clinical HIV tests detect antibodies to the virus, not the virus itself. HIV tests have a high incidence of false positives, so that retesting and other confirmation are needed after a positive test result. False positives of HIV testing may be the result of non-HIV AIDS caused by other diseases and pregnancy because the HIV tests are non-specific and may detect antibodies to other diseases or conditions.

Causes of False Positives:  HIV testing is not specific to HIV and is prone to false positives. It tests for antibodies to HIV, not the virus itself, but can also detect other antibodies present in chronic diseases or those acquired over a lifetime.  There are over 65 documented causes of false positives including TB, malaria, leprosy, hepatitis, Q fever, influenza or colds, herpes simplex, leishmaniosis, and Epstein Barr virus.  Pregnancy or prior pregnancies are among factors that can cause false positives due to presence of HLA (human leukocyte antigen). Is it time to question whether HIV testing, without thorough validation, is valid in parts of Africa where the population is routinely exposed to numerous diseases that leave a heavy load of antibodies in their blood?

Validation needed for HIV positives:  False positives are common so that, according to manufacturers’ instructions, positive tests must be retested in duplicate and then by another method to verify results, e.g. ELISA twice then Western Blot.  ELISA, Enzyme Linked ImmunoSorbent Assay, uses an antigen for the (in this case HIV) antibody bound to a solid surface and an enzyme that causes a color change when the target antibody attaches itself to the antigen.  Western Blot actually separates, by gel electrophoresis, each component in a mixture of antibodies bound to specific antigens. Medical testing protocols vary from country to country, so that the same test may be interpreted as positive or negative depending on the protocol. For example, UK does not use the Western Blot verification of duplicate ELISA tests, and different countries require from one to four Western Blot markers to verify and confirm a positive result.

South Africa uses duplicate ELISA only to verify positive HIV tests, resulting in 15-25% of the population testing positive, 60% of which are heterosexual women. South Africa also has a high rate of drug treatment for prevention of mother to child HIV transmission, which may mean that most HIV tests are conducted at gynecological clinics and obstetric hospitals on pregnant women. This is a problem since pregnancy is known to cause false positives. The incidence of HIV and AIDS in most of the other countries in Africa, and indeed the world, ranges from 0.1 to 5.0 percent of the population. South Africa’s 15 – 25% incidence needs a closer look. The fact that over half of these are heterosexual women is also problematic as described above.

Recommendation:  South Africans and Botswanans when first diagnosed with HIV or HIV/AIDS need to be retested using a more stringent verification protocol in the future. Unfortunately, the drugs used for treating HIV can cause false negatives, so retesting those already receiving therapy may be useless or at lease confusing.

Opportunistic Diseases: When people sicken and die with HIV/AIDS, it is not the HIV that kills them; it is other opportunistic infections that are able to invade and thrive because HIV has crippled the immune system. TB is the leading cause of death in Africa, with or without HIV/AIDS. A diagnosis of HIV/AIDS can be an excuse not to treat underlying endemic diseases.

Treatment Options:  HIV treatment drugs suppress the immune system further than the disease itself. Wouldn’t it make sense to treat the opportunistic diseases and malnutrition more aggressively first before suppressing the immune system further with AIDS treatment drugs?  In some areas of Africa, TB and HIV are treated simultaneously, which is a step in the right direction.

Orphans from AIDS? AIDS orphans are defined as anyone 15 years or younger who has lost, depending on the country, their mother, one parent or both parents to “AIDS related diseases.” South Africa includes people up to 18 years old.  WHO estimates that 70% of “AIDS orphans” have one living parent.  TB is the leading cause of death in Africa and the leading clinical indicator of the presence of AIDS.  Since many people in Africa live very short lives, with or without AIDS, how is this any different from the pattern of the past where lifespans are short and teenagers often are orphaned?

Bad Science, Politics and Magical Thinking

from website Compoundchem.com archive, April, 2014

How Bad Science and Emotional Appeals Spread Disinformation.

In today’s world, there is more false and misleading “information” than there is good science that is based on facts and not emotions and mythical or wishful beliefs. Much of what you see is either false or overblown. How can you know what to believe? It’s easy for me to say “Do your own research,” but that is often asking too much of most people who do not have analytical minds which have a habit of using critical thinking, much less have training in interpretation of scientific testing and results.  Today’s sensational and social media agenda are often driven by emotions, ideologies, politics, commercial aims or just plain stinking thinking.  The image above can help you understand factors that are important to discern fact from fiction, speculation and mythology.

Anecdotal stories do not constitute facts. Correlation does not mean causation. The flawed reasoning goes something like this: John ate a lot of apples. John got heart disease or cancer. Therefore, apples (or some chemical on them) caused John to develop heart disease or cancer. More examples of people who ate apples and got heart disease or cancer do not constitute proof that they cause disease.  Correlation does not mean causation. Maybe it is just two unrelated facts that are paired for sensational effect or to intentionally mislead you.

In humans, there are a lot of lifestyle and workplace differences between people, so one factor (apple) cannot be said to be a cause of anything without taking into consideration what else could contribute or cause the effect. Other factors such as obesity, alcohol, smoking, sedentary lifestyle, sleep habits, age, heredity, other risky behavior, etc. have to be ruled out in closely controlled studies. Small numbers of examples that seem to support the premise do not constitute “clinical trials” or proof.  To be statistically significant, very large numbers must be included along with control groups that do not use the suspected substance, preferably in a double blind study.  (double blind means neither the subject or the person giving the substance know which are real and which are placebo so their attitude cannot affect the result.)  I’m sorry, but Reader’s Digest and Facebook “statistics” are often flawed and any conclusions must be questioned and examined closely, even if it seems to come from a reliable source or even your grandmother.

It is wise to consider the source. There are powerful advocacy groups pushing agendas having nothing to do with real science or caring for your safety, which they claim.  These include anti-vaxx, organic anti-modern agriculture, anti-pesticide, anti-fossil fuel, in general anti-human progress groups that influence national and international agencies to act out of a preponderance of caution. The precautionary principle, used in the European Union, stops all progress in its tracks. If a substance with no presently known safety issues may possibly, conceivably cause some unforeseen harm in the future it cannot be used. It is also unscientific because it demands proving a negative.

Word to the wise: Be cautious and suspicious of any health claim you read or hear about.  There is often an agenda driven ideology or money-making scheme behind it.

The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary.                             —H. L. Menchen

Water Wars: Wind Turbine Construction Destroying Underground Water Supplies in Ontario

STOP THESE THINGS

Pundits have predicted that the next major war will be sparked over water. In Ontario just such a battle is (pardon the pun) well underway.

A couple of weeks back STT reported on the destruction of underground water supplies in Chatham-Kent: Ontario: Water, Water Everywhere – But Thanks to Wind Turbines – Not A Drop to Drink

While that story has clocked up almost 4,000 hits, it seems we only just scratched the surface.

Locals are furious, not just at the fact that once pristine water supplies have been turned to toxic sludge, they are wild at the way wind power outfits and their pet consultants are lying about the cause.

The first story goes right to the heart of that piece of wind industry spin.

Beating World Hunger

How we are beating hunger in 5 graphs

August 31, 2016
By Chelsea Follett

It can be hard to remember that even in wealthy countries, food has not always been abundant, and in many parts of the world hunger remains a problem. Fortunately, we are making great headway towards solving it. Here are five charts summarizing the incredible progress that humanity has made against hunger.

1. According to data from the United Nations, as recently as 1992, over a quarter of the world’s population was undernourished. Since then, a dramatic decline in hunger has occurred, particularly in places like China where economic liberalization has led to rapid development. In 2015, the share of the world population suffering from undernourishment had fallen to about 18 percent, while in China it had fallen even further, to less than 10 percent.Hunger graph 12. Not only do fewer people go hungry as a share of the population, but the total number of people suffering from hunger has also declined. Despite population growth, the number of undernourished persons has fallen from over 950 million in 1992 to about 685 million in 2015. That’s almost 270 million fewer undernourished people or a 28 percent reduction. China saw a more dramatic reduction of 51 percent. In 2015, 150 million fewer Chinese were undernourished than in 1992.Hunger graph 23. And even those who are malnourished are less severely malnourished. The average caloric shortfall among food-deprived persons (i.e., the number of calories by which they come up short of their daily requirement) has been shrinking. In 1992, a malnourished person typically consumed around 170 fewer calories per day than they needed. In China, the malnourished consumed 190 calories less than needed, on average. By 2015, the shortfall had decreased to about 100 calories worldwide and only 85 calories in China.Hunger graph 34. How has all of this progress been possible? In order to decrease hunger and feed a growing population, humanity has stepped up to the challenge by producing more food. The amount of food produced per person worldwide is now 20 percent greaterthan what it was back in 2005. And back in 2005 it was almost double of what it was back in 1961. Thanks to the Green Revolution and subsequent innovations, crop yields (i.e., the amount of food produced per unit of land) have also risen. By producing more food per hectare, we are able to spare more land for other uses and better preserve the environment. Consider cereal yields:Hunger graph 45. Importantly, as the food supply has risen, the cost of food has also fallen, on average. The price index shown below has been adjusted for inflation and represents a composite of eighteen crop and livestock prices weighted by their share of global agricultural trade. Despite an uptick in food prices since 2001, the long-term trend is clearly one of decline. Today, the cost of food is less than half of what it was back in 1900.Hunger graph 5

DDT is needed now more than ever (revised/reposted)

Bring back DDT – Save Africa and other impoverished areasAonpheles mosquito feeding

Over 80% of infectious diseases are caused by insects and other arthropods. DDT is desperately needed in impoverished countries where insect borne diseases kill and sicken millions every year, cutting lifespans and productivity.  Africa, India and South-Central Americas are most affected. This unpardonable crime amounts to continuing genocide of brown races by western powers.

Without these insect borne diseases, populations may increase at first, but better health will facilitate the building of infrastructure, agriculture and industry that can raise millions out of poverty, ignorance and hopelessness.  These changes will benefit the environment, because healthy people raised above dire poverty will be able to care for their environment.  Recent claims of mosquito resistance to DDT are grossly overblown and used as an excuse to prevent resumption for insect control.  WHO has required proof of NO resistance for its use in an area, but that requires proving a negative, which is impossible. The aim is not to kill every mosquito, but to reduce or eliminate the transmission of malaria and other diseases between insect vectors and humans.  Mosquitos emerge clean and must acquire malaria from infected people.  That’s why it did not return to countries where it was eliminated. Break the cycle to end the misery.


“How much labor and waste of time these wicked insects do cause, but a ray of hope, in the use of DDT, is now held out to us.”            — Out of My Life and Thought: An Autobiography, Dr. Albert Schweitzer (translated from Ma Vie et Ma Pensee)


DDT worked so well that malaria and similar diseases were eradicated in most developed countries and were near eradication in poorer countries before DDT was banned in 1972 by EPA in spite of failure to find any harm to humans or the environment by an overwhelming body of research.


“To only a few chemicals does man owe as great a debt as to DDT. It has contributed to the great increase in agricultural productivity, while sparing countless humanity from a host of diseases, most notably, perhaps, scrub typhus and malaria. Indeed, it is estimated that, in little more than two decades, DDT has prevented 500 million deaths due to malaria that would otherwise have been inevitable. Abandonment of this valuable insecticide should be undertaken only at such time and in such places as it is evident that the prospective gain to humanity exceeds the consequent losses. At this writing, all available substitutes for DDT are both more expensive per crop-year and decidedly more hazardous.”

— National Academy of Sciences, Committee on Research in the Life Sciences of the Committee on Science and Public Policy, The Life Sciences: Recent Progress and Application to Human Affairs, The World of Biological Research, Requirements for the Future (Washington, D.C.: GPO, 1970), 432.                             (Emphasis added)


Rachel Carson’s 1962 book, Silent Spring, was filled with lies, half-truths, misinterpretation of research results and wild speculations.  Rather than being an attempt to protect humans and the environment as stated, it was really part of an effort to stop population increases in Africa, India and other impoverished countries.


“My own doubts came when DDT was introduced for civilian use. In Guyana, within two years it had almost eliminated malaria, but at the same time the birth rate had doubled. So my chief quarrel with DDT in hindsight is that it has greatly added to the population problem.”

                          —Alexander King, cofounder of the Club of Rome, 1990


Population Bomb by Paul Erilich (1968) was a another book based on Malthusian, (overpopulation), eugenicist, racist lies, aka propaganda.


“The battle to feed all of humanity is over. In the 1970s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now. At this late date nothing can prevent a substantial increase in the world death rate…”                              — Paul Ehrlich, The Population Bomb, 1968


Population control groups such as the Club of Rome, supported by charitable foundations such as the Rockefeller Foundation, continue to spread the myth of overpopulation.  Many rural areas have too few healthy people to build roads, other infrastructure and industry.

In 1972 DDT was banned by US EPA Administrator William Ruckelshaus in spite of overwhelming scientific evidence presented at hearings that refuted claims of harm by activist groups such as Environmental Defense Fund and Audubon Society.


“DDT is not a carcinogenic, mutagenic, or teratogenic hazard to man. The uses under regulations involved here do not have a deleterious effect on fresh water fish, estuarine organisms, wild birds, or other wildlife…and…there is a present need for essential uses of DDT.”                — EPA Administrative Law Judge Edmund Sweeney, after months of hearings, “In the Matter of Stevens Industries, Inc., et al., L.F. & R. Docket Nos. 63, et al.). Hearing Examiner’s Recommended Findings, Conclusions, and Orders, April 1972.” (40 CFR 164.32). (Consolidated DDT Hearings)  As summarized in Barrons, May 1, 1972


Note that this case was brought on behalf of the Environmental Defense Fund, an advocacy group that opposed any use of modern fertilizers and pesticides as harmful to the environment, regardless of evidence to the contrary.

Beginning in the 1970’s, US AID, UN WHO, UNESCO and the World Bank have pressured leaders of poor countries to discontinue DDT as a prerequisite to receiving essential aid. This continues to the present with exception of WHO recently allowing limited spraying of interior walls in selected areas.

Although DDT is the most studied pesticide on the planet, it is still listed as an environmental toxin and possible carcinogen because the EPA listing has not been changed, in spite of all of the studies that failed to find harmful effects on humans or the environment.  It is much safer and more economical than any of the proposed replacements.

Verifying the Claims of Silent Spring

None of Rachel Carson’s “facts” about environmental and human harm were true. Most of the facts below, except where noted, are from “DDT: A Study in Scientific Fraud,” by J. Gordon Edwards, Journal of American Physicians and Surgeons Volume 9 Number 3 Fall 2004. (See link below)

Dr. Edwards examined each of Silent Spring’s claims and found them wrong and possibly fraudulent.

Not one person has been harmed or died from DDT.

  • The only death associated with DDT was a 3 yr. old child that drank a solution of DDT in kerosene, which is a hydrocarbon known to be toxic.
  • J. Gordon Edwards was a Ph.D. entomologist who sometimes ate a spoonful of DDT powder at his lectures as a demonstration of its safety. He suffered no significant ill effects and died of a heart attack at age 84 while hiking in the Rockies.

DDT is not carcinogenic, mutagenic or teratogenic

  • “Workers in the Montrose Chemical Company had 1,300 man-years of exposure, and there was never any case of cancer during 19 years of continuous exposure to about 17mg/man/day.”
  • “Concerns were sometimes raised about possible carcinogenic effects of DDT, but instead its metabolites were often found to be anti-carcinogenic, significantly reducing tumors in rats.”
  • Expected rise in leukemia in children and breast cancer years later in girls exposed during puberty never happened.

Bird deaths, thin egg shells and buildup in the environment have proven to be false.

  • Bird deaths at the University of Michigan, cited by Carson, were not from DDT, but were probably from soil fungicide containing mercury. In later tests, mercury was found in the soil and earthworms there. Other areas did not experience bird deaths from spraying of DDT. Carson’s Source was: Bird Mortality in the Dutch elm disease program in Michigan, Bulletin 41, Cranebrook Institute of Science by George John Wallace; Walter P Nickell; Richard F Bernard
  • According to Audubon Society Annual Christmas Bird Counts, bird populations actually increased during the thirty years of DDT use. Numbers rose from 90 birds seen per observer in 1941 to 971 birds seen per observer in 1960.
  • The eggshell thinning studies cited by Carson could not be replicated and had actually reduced dietary calcium, needed to build egg shells, of experimental birds to get that result.
  • Museum specimens compared to wild population eggs may have led to false claims of thinning because the museums used the best specimens available; natural variability in the wild may have been interpreted as thinning. “the whole idea that pesticides are concentrated as one moves up the food chain, which is crucial to Carson’s arguments about distant and delayed effects, has become increasingly dubious in the years that followed” (Fleming, New Conservation Movement, 31). Source: Reading Rachel Carson by Charles T. Rubin
  • DDT is not metabolized by birds and is rapidly excreted in their droppings.
  • “The counts of raptorial birds migrating over Hawk Mountain, Pennsylvania, indicated that there were many more hawks there during the “DDT years” than previously. The numbers counted there increased from 9,291 in 1946 (before much DDT was used) to 13,616 in 1963 and 29,765 in 1968, after 15 years of heavy DDT use.”

Aquatic life has not been harmed by DDT; it is practically insoluble in water, with only 1.2 parts per billion at saturation.

  • A study cited by Carson claimed 500 ppb DDT in seawater inhibited photosynthesis and killed algae. The problem with this study is that alcohol was added to the tank to dissolve the DDT in the water. Alcohol alone would do that.
  • The assumption of persistence of DDT in seawater for decades was also challenged. Tests showed DDT and its metabolites disappeared in as few as 38 days.
