ABC, NBC and MSNBC Prime-Time Shows Ignored Landmark UN Report on Biodiversity
By Ted MacDonald
On the day the report was released, three of the networks — ABC, NBC and MSNBC — aired no prime-time coverage of it, while the other three networks each aired one prime-time segment. Out of 26 total prime-time news programs on the networks, only three reported on the UN assessment.
Major UN Report Warns of Extinction Crisis That Will Have Major Impacts on Humanity
A summary report released by the UN on May 6 finds that about 1 million plant and animal species are at risk of extinction due to expansive human development. The current extinction rate is "at least tens to hundreds of times higher than it has averaged over the past 10 million years." The global assessment, compiled by hundreds of experts with data drawn from thousands of studies, is the most comprehensive look yet at the rapid decline in planetary biodiversity. The report points to a number of human activities that are affecting biodiversity, including overfishing, poaching, farming, mining, logging and polluting. Climate change is also playing a large role in fueling the biodiversity crisis. And the loss of biodiversity in turn threatens humans by endangering water and food supplies and heightening the risks from floods and hurricanes.
The full report is set to be published later in 2019. But even with this summary, the authors show that the biodiversity and climate crises are directly intertwined, ultimately painting a grim picture about the state of our natural world.
Only One of Three Broadcast Nightly News Shows Covered the UN Biodiversity Assessment
Media Matters analyzed the major broadcast networks' nightly news programs on May 6, as well as cable news coverage from 4 p.m. to midnight.
On the broadcast networks, neither ABC's World News Tonight nor NBC Nightly News mentioned the UN biodiversity assessment. Significant segments on these networks instead focused on a Russian airplane fire, former Trump attorney Michael Cohen reporting to prison, and the birth of a royal baby in Britain. CBS Evening News was the only broadcast nightly news program to air a segment on the biodiversity report.
It should come as no surprise that ABC's flagship news program failed to cover the report; the network's news shows consistently lag behind their broadcast competitors in covering climate change. In 2018, ABC aired less than 11 minutes of climate coverage on its nightly and Sunday morning news programs, far less than its counterparts. In fact, ABC has spent less time on climate coverage than CBS and NBC every year since 2013.
On Cable, MSNBC Failed to Mention the Biodiversity Report in Its Prime-Time Coverage
None of the prime-time news shows on MSNBC on May 6 mentioned the UN biodiversity assessment. Much of the news coverage on the network that night focused on the Mueller report.
The only prime-time cable shows to mention the global assessment were CNN's The Lead with Jake Tapper and Fox News' Special Report with Bret Baier. Coverage on The Lead was straightforward, while Special Report's coverage was riddled with skepticism. Baier, who is billed as one of Fox's "news"-side reporters, began the segment by saying, "Many environmentalists are in a panic tonight over a new report," but "as in all such cases, some humans say the report and the response are exaggerations." The segment included commentary from industry-funded climate denier Marc Morano, who has no background in science. Morano downplayed the report and accused the UN of being a "self-interested lobbying organization." (The Morano footage had run previously on another of Fox's "news"-side programs, Shepard Smith Reporting.)
By Neglecting a Major Report About Threats to Life on Earth, TV Networks Are Failing Their Viewers
The extinction of threatened species will have serious human consequences. One takeaway from the UN assessment is the need to promote a better understanding of the fact that nature is the foundation for human development and all life on Earth. The media has a responsibility to help build an informed citizenry that understands the world it inhabits. By giving this report far too little attention, top TV networks have failed their audiences.
Media Matters analyzed coverage on May 6 on the major broadcast networks' nightly news programs (ABC's World News Tonight, CBS Evening News, and NBC Nightly News) and on shows airing from 4 p.m. to midnight on the major cable news networks (CNN, Fox News and MSNBC). We identified segments on the UN biodiversity assessment by searching IQ Media and Nexis for the terms (nature or biodiversity or extinction or extinct or climate or species or planet) and (report or study).

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>
