James Lovelock, Gaia theory guy. He was 103.
But his global renown rested on three main contributions that he developed during a particularly abundant decade of scientific exploration and curiosity stretching from the late 1950s through the last half of the ’60s.
One was his invention of the Electron Capture Detector, an inexpensive, portable, exquisitely sensitive device used to help measure the spread of toxic man-made compounds in the environment. The device provided the scientific foundations of Rachel Carson’s 1962 book, “Silent Spring,” a catalyst of the environmental movement.
The detector also helped provide the basis for regulations in the United States and in other nations that banned harmful chemicals like DDT and PCBs and that sharply reduced the use of hundreds of other compounds as well as the public’s exposure to them.
I’m setting aside, for the moment, the arguments over the legacy of “Silent Spring”. Folks are welcome to discuss that in the comments if they’d like.
Later, his finding that chlorofluorocarbons — the compounds that powered aerosol cans and were used to cool refrigerators and air-conditioners — were present in measurable concentrations in the atmosphere led to the discovery of the hole in the ozone layer. (Chlorofluorocarbons are now banned in most countries under a 1987 international agreement.)
But Dr. Lovelock may be most widely known for his Gaia theory — that Earth functioned, as he put it, as a “living organism” that is able to “regulate its temperature and chemistry at a comfortable steady state.”
Personally, I think Gaia is a bunch of hooey. But the man did science, and deserves props, even if I don’t necessarily agree with everything he said. Also, he was married to the same woman for 47 years, until she passed.
The Choco Taco. I’ve always liked those, but it’s been a while since I’ve had one. Cause of death is given as COVID related supply chain issues. But I’ve seen assertions elsewhere that it was cancelled due to “cultural appropriation”. I’m not sure how serious that claim is…
