Storyline

To determine the true age of the Earth, geochemist Clair Patterson developed the uranium-lead dating method to make an unprecedented discovery - calculating Earth's age of 4.5 billion years. But Patterson's groundbreaking discoveries were just beginning. Patterson made it his mission to draw public attention to the detrimental effects of lead in the environment and dedicated his career to fighting against the petroleum and chemical industry, eventually achieving public health's biggest victory of the 20th century.

Goofs

Much of this episode focuses on leaded gasoline as a significant contributor to atmospheric lead content. However, it is incorrectly implied that leaded gasoline was phased out as a result. In reality, it was the widespread introduction of catalytic converters in new automobiles starting in 1975 that drove the switch to unleaded gasoline. See more »

It Is About Science
20 January 2015 | by HitchcocSee all my reviews

Others have stated that if a show has advocacy, even if it is based on scientific proof, it is inadequate as documentary. This show is about Claire "Pat" Patterson who dedicated his life to two issues: finding the age of the Earth and dealing with the preponderance of lead in our atmosphere, our products, and our oceans. He is perhaps one of the most heroic people in our history, and one who nobody knows. The fact of the matter is that when money is talking, a lot of discourse is over. The climate change issue is just the next in a series of factors that are being debated because massive death and destruction in the future doesn't affect the current generation. Whether the narrator has an agenda is not an issue. There is no such thing as a presentation without some agenda. I assume if the presentation said there was no climate change, it would have gotten ten stars. Once again, a masterful telling of a great investigation and the courageous efforts to get the word out.
