Inauguration Day 2017: A Turning Point
Not since the Civil War has an American presidential Inauguration Day been so fraught with fear and dread (on Feb. 23, 1861, Abraham Lincoln traveled to his inauguration under military guard, arriving in Washington, DC, in disguise). The incoming president is the most unpopular of any to assume office since modern polling began. In a single news cycle this past week he managed to alienate allies throughout an entire continent (Europe) during a brief break in a string of petulant tweets intended to persuade his own nation that Saturday Night Live is "not funny ... really bad television!"

Much has been made of the new president's personality and psyche—his narcissism, his germophobia, his irritability, his minimal sleeping habits and his reported inability to laugh (though he does smile). In my view, the most revealing personal characteristic of president #45 may be his complete disconnection from the natural world. Here is an individual who grew up in a city, who sees land only in terms of profit potential, who proudly covers the tortured ground with high-rise buildings, who lives in a penthouse and who walks outdoors only on golf courses. One could make some similar comments about many of his recent predecessors (certainly not Teddy Roosevelt), but in this instance the tendency reaches an extreme.
How can a person so isolated from natural phenomena hope to understand the vulnerability of our planet's climate, water, air and innumerable species to the actions of people (one hastens to add—people much like himself)? How can he appreciate that civilization itself is an organism with a constant need for "food" (not just grain and meat, but energy, minerals and water as well), that is organized by way of hierarchically ordered and interlinked cycles and that is subject to natural limits and ultimately to death?
One could argue that all hubris is tied to human beings' illusion of dominance over nature. Our long withdrawal from wildness surely started with language, which gave us the ability to name and categorize and thus to psychically control and distance ourselves from what we named; it erupted into alienation with the advent of agriculture, cities and most recently fossil fuels. But we never stopped depending on the fabric of life in which we have always been entwined. Even as we unravel the ecosphere's delicate fibers, we draw upon eons of accumulated soil nutrients and minerals, fresh water and biodiversity.
Life implies death—one's own mortality above all. Everything has limits. Wisdom resides in the understanding that we are subject to forces we cannot control and that we must respect and accommodate ourselves to those forces. If we want to have language, farming, cities and energy, then we must make a deliberate cultural effort to maintain an attitude of individual and collective humility. In practical terms, that means keeping the size of our global population low enough so that it can be supported long-term without eroding natural systems, managing consumption so that resources are not depleted and non-biodegradable wastes do not accumulate and maintaining checks on wealth inequality.

Obviously, we haven't been doing these things very well, especially in recent decades. The power of fossil fuels fed our collective megalomania. Like people in previous civilizations, we went out on a limb—but modern energy and technology enabled us to go much further than any humans had before. Still, as all civilizations do, ours has reached the point of diminishing returns, of over-reach. Before us lies the senescence and death of a way of living and of seeing the world. Perhaps the new president's qualities of character are emblematic of these final stages of cultural disintegration.
In the days to come, there will be plenty of opportunities for resistance, protest and, one hopes, celebration. Inauguration Day 2017 is a turning point; for me, it seems a perfect occasion for a walk in the woods.

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.
Where Does the Deficiency Begin?<p>Nobody knows exactly how much vitamin D a person actually needs. The question of when a deficiency starts is correspondingly controversial. However, vitamin D is becoming increasingly popular.Not only is the pseudo-scientific literature on the "sun vitamin" experiencing an upswing, but the number of published studies has also increased enormously in recent years. For example, in 2019 <a href="https://academic.oup.com/edrv/article/40/4/1109/5126915" target="_blank">a study found that</a> Vitamin D is responsible for keeping the skeleton functional and is associated with cardiovascular diseases, type 2 diabetes and various types of cancer. <br></p>
An All-Rounder<p>Vitamin D levels in the body rise and fall according to sun exposure. If sufficient UV rays reach the skin, the body is able to produce the vitamin itself. However, the human body only derives an estimated 10 to 20 percent of its daily requirement from food.</p><p>The vitamin D that we synthesize from sunlight or food is not biologically active at first. Before the kidneys can produce the biologically active form of the vitamin, known as calcitriol, and release it into the blood, some metabolic processes must take place beforehand.</p><p>In addition, many organs have receptors to which the precursor of calcitriol binds. Further, this substance is also present in blood.</p><p>From this precursor, the organs then produce calcitriol themselves, which the body then uses for countless other processes in the body. This form of vitamin D thus regulates insulin secretion, inhibits tumor growth, and promotes the formation of red blood cells as well as the survival and activity of macrophages, which are important for the <a href="https://www.mdpi.com/2072-6643/5/7/2502/htm" target="_blank">immune system.</a></p>
Low Vitamin D, Severe COVID-19 Disease?<p>A research study carried out <a href="https://www.sciencedirect.com/science/article/pii/S2352364620300067?via%3Dihub" target="_blank">at the University of Hohenheim</a> has now established a link between vitamin D deficiency, certain previous diseases, and severe cases of COVID-19.</p><p>According to the study, "there is a lot of evidence that several non-communicable diseases (high blood pressure, diabetes, cardiovascular diseases, metabolic syndrome) are associated with low vitamin D plasma levels. These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe COVID-19 events."</p><p>"This statement is completely correct," said Martin Fassnacht, head of endocrinology at the University Hospital of Würzburg. However, he qualifies that it is a pure association, "i.e. a mere observation that these events occur together.</p><p>Dr. Fassnacht is very critical of the hype surrounding vitamin D, but not because he denies the vitamin serves important functions. However, studies on humans have not been able to show that vitamin D has the healing powers many often propagate.</p><p>Fassnacht says, "If you take a closer look, the hopes that the administration of vitamin D has a healing effect have not been confirmed so far."</p>
Association Versus Intervention Studies<p>Many studies on the vitamin are association or observational studies. "By definition, these studies cannot prove the causal relationship, but only point to mere correlations," said Fassnacht. The physician tries to illustrate this with an example:</p><p>"Imagine two groups of 80-year-olds. One group is spry, active and does sports. If you compare them with another group living in nursing homes, the difference in vitamin D levels will be dramatic. Life expectancy would also be extremely different."</p><p>But to try to explain the difference in fitness by vitamin D status alone is far too simplistic. "Vitamin D levels are a good measure of how sick someone is. But not more," says Fassnacht. </p><p>According to Fassnacht, none of the intervention studies carried out to date -- that specifically examined the effect of vitamin D on various diseases -- has been able to confirm the previous association and laboratory studies or the presumed positive effect of vitamin D.</p>
Further Research Is Needed<p>"If a coronavirus infection is suspected, it is therefore absolutely necessary to check the vitamin D status and quickly correct any possible deficit," said the recommendation of the paper published by the University of Hohenheim.</p><p>"Studies are underway to see whether vitamin D helps in COVID-19 infection, but I personally do not believe that this is really the case," says endocrinologist Fassnacht. Nevertheless, he says it is of course useful to carry out these studies.<br></p><p>"I don't want to rule out that there are actually subgroups of people who benefit from an additional vitamin D dose," he says. After all, this has been proven to be the case with a severe deficit.</p><p>In view of the study situation, Fassnacht does not think much of preventive, nationwide vitamin D substitutes. "My belief that the vitamin helps somewhere is very low. But, of course, I can be wrong."</p>
