Conservation and 'Renewed Hope': Mountain Gorilla Numbers Rebound
First, the good news. Collaborative conservation efforts have brought "renewed hope" for mountain gorillas and two large whale species, according to today's update from the International Union for Conservation of Nature's (IUCN) Red List of Threatened Species.
The mountain gorilla subspecies moved from "critically endangered" to "endangered" due to anti-poaching patrols and veterinary interventions. In 2008, their population dropped to as low as 680 individuals––but the new estimates reveal that the number of mountain gorillas has increased to more than 1,000 individuals—the highest figure ever recorded for the eastern gorilla subspecies, the IUCN said.

Meanwhile, the fin whale's status moved from "endangered" to "vulnerable" and the western subpopulation of the gray whale moved from "critically endangered" to "endangered."
"These whales are recovering largely thanks to bans on commercial hunting, international agreements and various protection measures," Randall Reeves of the IUCN cetacean specialist group said in a press release. "Conservation efforts must continue until the populations are no longer threatened."
Now, the bad news. The Red List update shows that other flora and fauna are under threat due to overexploitation, including the globally important vene timber tree (now "endangered"), the aquilaria agarwood that's prized for its fragrant wood (13 out of 20 species are threatened with extinction), the giant bolson tortoise of North America (now "critically endangered"), and the pungent and endangered "corpse flower" that is now in decline due to logging and destruction of the plant's habitat from palm oil plantations.
Not only that, the assessment also shows that 13 percent of the world's grouper species and 9 percent of Lake Malawi fish are now threatened with extinction.

"At least two billion people depend directly on inland freshwater fisheries such as Lake Malawi for their survival," William Darwall, head of IUCN's Freshwater Species Unit, explained in the press release. "Almost 80 percent of catch from freshwater fisheries comes from food-deficit countries—where the general population does not have sufficient food to meet recommended daily calorie intake—yet freshwater resources are not prioritized on national or international agendas. Target 6 of the UN Strategic Plan for Biodiversity, focused on avoidance of overfishing, will therefore be missed. This omission puts local livelihoods at risk and increases the risk of food insecurity across the world."
The Red List now includes 96,951 species of which 26,840 are threatened with extinction. The report was released as governments gather for the Convention on Biological Diversity conference this week in Egypt.
"Unfortunately, the latest update also underlines how threats to biodiversity continue to undermine some of society's most important goals, including food security," IUCN Director General Inger Andersen said in the press release. "We urgently need to see effective conservation action strengthened and sustained. The ongoing UN biodiversity summit in Egypt provides a valuable opportunity for decisive action to protect the diversity of life on our planet."

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>
