I recently caught up on my Netflix queue and watched episode seven of Cosmos, and was delighted to learn about one of the greatest heroes of the 20th century that I had never heard of.

The US Centers for Disease Control and Prevention (CDC) has called water fluoridation the greatest public health achievement of the 20th Century. Clearly, they got that WRONG.

Many have forgotten that leaded gasoline was used for 80 years before the lead was removed, despite the fact that its toxicity has been known for at least 2,000 years.

Clair Patterson, PhD was instrumental in defeating the oil industry and getting lead removed from gas, and that definitely beats water fluoridation in terms of protecting public health.
