Declining sperm counts: Nature's answer to overpopulation?

Epidemiologist Shanna Swan projects that on current trends sperm counts will reach zero by 2045. That shocking conclusion comes from a new book by Swan and her colleague Stacey Colino. Is this nature's way of bringing human population under control? (More on that later.)

In a 2017 study Swan and colleagues looked at "244 estimates of SC [sperm concentration] and TSC [total sperm count] from 185 studies of 42,935 men who provided semen samples in 1973–2011" in North America, Europe, Australia and New Zealand. Men elsewhere may fare better, but the causes of this trend suggest that it is worldwide.

Swan told The Guardian that she blames so-called "'everywhere chemicals', found in plastics, cosmetics and pesticides, that affect endocrines such as phthalates and bisphenol-A." She also pointed to unhealthy lifestyle choices including use of tobacco and marijuana and to rising obesity. Obesity itself has been linked to increasing human endocrine disruption from these same chemicals.

Things (nearly) fall apart: The year so far in electricity, finance and computer chips

We are less than two months into the new year and the news is full of stories about a system whose rivets are about to pop en masse and send us—the United States and maybe the world as whole—into a catastrophic systemic downward spiral in critical areas.

The first thing to understand is that these disparate calamities are all intimately related in that they arise out of system that applies certain "principles" across sectors of society. Those principles have their origin in rigid economic ideology, but their effect has been to further enrich those at the top—which is why elites keep defending these discredited approaches.

Let us take Texas utility customers who shivered through rolling electricity blackouts last week designed to keep the electric grid from cratering altogether under the strain of record demand. The demand resulted from a polar-vortex-induced cold snap that brought record low temperatures to much of the southern plains states and the Midwest. The reason for the spiking demand was simple: 60 percent of homes in Texas use electricity for heating.

Demateralizing the economy isn't happening (Hint: All that material is actually hiding in plain sight)

If you are trying to prove something is true and certain facts get in the way, it's almost always useful to exclude them. This is apparently what technology cheerleader Andrew McAfee has done in his recent book More from Less, which claims that advanced economies have been dematerializing for something like the last 40 years. Simply put, those economies are producing more output with little or no increase in physical resources.

There's just one little problem as anthropologist Jason Hickel points out in his review of More from Less: McAfee forgot to count the physical resources used in making products imported from other countries by all those advanced economies. McAfee only counts those resources extracted within the boundaries of the advanced countries.

I am highlighting Hickel's piece not so much as a book review. There are dozens of books making similar ridiculous claims that are contradicted by the facts. I am highlighting the piece because Hickel provides perhaps the clearest, most concise refutation of the nonsense that McAfee and others like him are peddling.

Let me touch on the high points though I encourage you to read the full article:

The clickbait future of news and our crisis of consensus

It's often hard to distinguish between what has come to be known as "clickbait"—which according to Dictionary.com is "a sensationalized headline or piece of text on the internet designed to entice people to follow a link to an article on another web page"—and simply a clever headline.

What irks me about true clickbait headlines is that the story often contradicts or fails to mention the claim made in the headline. Of course, if the entire story is merely fabricated or exaggerated in ways that obscure what is actually going on, that is a problem, too.

News organizations are no strangers to sensationalized headlines. In fact, the newspaper business invented an entire category for what is called clickbait, namely, tabloids. The often repeated adage that "if it bleeds, it leads" is reaffirmed on a daily basis.
