Preterm birth is the "leading cause of long-term neurological disabilities in children."

In 2013, I began focusing on pregnancy and neurodevelopment:

Fluoride, Premature Birth and Impaired Neurodevelopment
A global review of recent laboratory, clinical, and ecological evidence that fluoride is a significant risk factor for premature birth and long-term neurological disabilities in children. Townsend Letter, 2013.

Placental Fluorosis: Fluoride and Preeclampsia
New research and diverse evidence implicate fluoride and fluorosis in the pathogenesis of preeclampsia, the dangerous pregnancy complication caused by the abnormal placenta. Townsend Letter, 2015.

Prenatal Fluoride and Autism
Fluoride swallowed in amniotic fluid may disrupt colonization and composition of bacteria in the fetal GI tract – adversely affecting neurological and immunological development. Townsend Letter, 2016.

This lead to a book published in 2017: Pregnancy and Fluoride Do Not Mix

Next came a website Pregnancy and Fluoride Do Not Mix
that highlights and updates evidence that validates the need and
the right of families to know the many risks of prenatal fluoride.

See Fluoridated Water is Risk for Premature Birth for supporting evidence.

27th Anniversary of GreatSeal.com in 2025

John's website about the history, symbolism, and relevance
of America's Great Seal first went online in 1998.
GreatSeal.com now has more than 100 pages & 300 images,
including several works of art John commissioned, including:

"a more perfect union"

In 2004, John was invited to give a slide show presentation
about the Great Seal during the 300th anniversary of Harriton House,
home of Charles Thomson, the principal designer of the Great Seal.

In 2017, John was interviewed Harriton House about the Great Seal for
"The Man Who Told the Truth," a BBC documentary about Charles Thomson:
an Irish orphan who became a central figure in the American Revolution.

Environmental Reports

We are the Whirled


Recover the Earth             Save the Seed

Read John's conversation with Ben Franklin about how the U.S. Constitution can help us
combat lead, an age-old enemy of the brain – inspired by Michael Diamond's book:
If You Can Keep It: A Constitutional Roadmap to Environmental Security
