The decline at the heart of the story. Values given are only relative to an arbitrary calibration standard
A new threat to all life on the planet?

Atmospheric oxygen levels are declining fast. Accompanied by scary graphs and even more frightening scenarios, the new environmental disaster of oxygen depletion seems poised to overtake the crumbling CO2 fright as the next great challenge to mankind's survival.

The story is already making converts in the media, which includes Peter Tatchell of the U.K. Guardian, who recently ran a breathless story on possible consequences, including "genetic mutations, hormonal changes...cancer, degenerative diseases" and even death. 

Tatchell says the rate of decline has dramatically increased in the past 30 years.  He calls for immediate "scientific research" to examine the problem, blissfully unaware that several dozen researchers have been doing just that for decades.  

The decline is predictably pinned on deforestation and mankind's "burning of fossil fuels". Once again, man is trashing the planet.  

The only problem? It's pure bunkum. Unlike the trace gas CO2, oxygen comprises over 20% of the atmosphere. Oxygen is the most abundant element in the earth's crust; it accounts for nearly 90% of the mass of the ocean. While we can't breathe water, atmospheric oxygen levels have been measured since the 1890s and haven't varied to within three significant digits (a tenth of a percentage point).

The fearsome decline seen in the sidebar graph is the result of misinterpretation. The values given are relative, not absolute, and correspond to changes of a few parts per million. With O2 levels currently at 210,000 ppm, the changes we measure won't be significant for tens of thousands of years, if then.

Dr. Andrew Manning of the Scripps Atmospheric Oxygen Research Group tells Daily Tech the miniscule rate of O2 decline is of "no concern whatsoever to human health or any ecosystem". According to Manning, while fossil fuels do consume oxygen, an ever-increasing amount of plant life in the biosphere offsets the loss.

So what is the source of this crackpot idea? It stems from the writings of interdisciplinary ex-professor Ervin Lazlo. Lazlo calls himself "the recognized founder of systems philosophy", a New Age holistic pseudo-science that has unfortunately accomplished nothing useful since he created it 35 years ago.

Lazlo is the founder of the Club of Budapest, an environmental group which specializes in "planetary consciousness". The group shares members and ideas with the Club of Rome best known for the "Limits to Growth" scare of the early 1970s. That led to a book of the same name, which became the best-selling environmental title of all time. The book was roundly called tripe by dozens of esteemed economists, and even later admitted to be nothing more than a caper to gain media attention -- none of which seemed to hurt sales. Even today one can still find environmentalists still quoting the book's conclusions as fact.  

The environmental movement has a long history of promoting scare stories without a shred of scientific backing. From "Silent Spring" which predicted the global death of all bird life, to forest-demolishing acid rain, to more modern scares such as Alar and GM foods, the poor track record of success seems to only stimulate a never-ending stream of new drivel.

At least this time around, you've been forewarned.

"why would we care about an economists opinion about the truthiness of an environmentalist book?"

Because 'Limits to Growth' was at its heart a set of economic predictions about the effect of dwindling resources on the economy over the next 30 years.

In any case, one doesn't need to appeal to authority to discredit the book. Its predictions all failed to come to pass. Prices of foods, metals, and other resources named in the book didn't skyrocket as supplies ran out -- we have more of them today than we did in 1972.

Aren't the Club of Rome guys the ones who lost a famous bet about the price of metals?

I believe you're talking about Simons bet against Paul Ehrlich:

Ehrlich wasn't a Club of Rome member, but many of their ideas originated from his kooky predictions.

Exactly; if environmentalists are talking about the effects of some compound on birds, that's for others to respond to. Attacking growth, resource utilization, etc., however is an attack on their very home turf. Growth and resource allocation/utilization/etc is what its all about, and what it's been all about since Xenophon, Plato, and other ancient world philosophers created the field. Therefore it's entirely rational for economists to comment on economic issues. One instead has to wonder what credibility environmentalists have on economics issues..
