The next big pipeline battle is shaping up in the marshes of southwestern Louisiana.
The standoff at the Standing Rock Sioux reservation against the Dakota Access Pipeline (DAPL) has energized activists in Louisiana, who are trying to keep another crude conduit out of wetlands that Louisianans have fought to restore for decades. The 162-mile Bayou Bridge Pipeline is the last of a network of oilfield arteries that includes DAPL. The project would run from southeastern Texas to a Mississippi River terminal in St. James Parish, west of New Orleans, after crossing the Atchafalaya River basin—a 1.4 million-acre swath of cypress marsh and wetland forest that's a key rest stop for birds moving north and south along the Mississippi Flyway.
"It's the largest swamp left in North America and it's historically the most critical habitat for migratory birds in the entire hemisphere," said Dean Wilson, executive director of Atchafalaya Basinkeeper. The murky waters of the Atchafalaya are teeming with fish, crawfish and crabs, making them a rich source of food for animals and people alike.
Wilson's organization is part of a coalition of Louisiana environmentalists seeking to block the pipeline, which includes the Sierra Club's Delta Chapter. They're trying to prevent further injury to a state where the oil industry puts food on many tables, but also has inflicted deep and dramatic losses on the landscape. The Atchafalaya watershed is already crisscrossed with thousands of miles of pipe; one more "is one too many," said Darryl Malek-Wiley, a Sierra Club organizer in New Orleans.
"As an ecosystem, it's actually more productive than the Everglades, as far as food value," Malek-Wiley said. "It's time to focus in on this and move forward in a positive way to protect the area, rather than to put more pipelines across it, which cause sediment backup and disturb the water flow through the basin."
As an offshoot of the Mississippi River, the Atchafalaya is a major part of southern Louisiana's flood protection system. In 2011, when rising waters threatened Baton Rouge and New Orleans, the Army Corps of Engineers opened spillways that diverted some of that flow through the basin. It's also the only part of coastal Louisiana that gained land area over the past several decades, as a combination of sinking land, sea-level rise and erosion accelerated by industrial canals eats away at the rest of the state's shoreline.
And it's not just the watershed that would be affected. Opponents say the 24-inch-diameter line would cross about 700 bodies of water, from bayous to backyard wells.
They're lined up against the state's powerful oil and gas industry, which employs about 30,000 people and supports tens of thousands more jobs. The area's Republican congressman and the state's Democratic governor both support the pipeline. Louisiana's Department of Natural Resources approved the project in April—and no sympathy is expected from the Trump administration, which reversed its predecessor's decision to halt the Dakota Access and Keystone XL pipelines across the northern Great Plains.
But the pipeline's builder, Energy Transfer Partners, still has to get permission from the state Department of Environmental Quality and the Corps of Engineers. Opponents have asked the Department of Natural Resources to reconsider its approval, and argue that the pipeline would piggyback on infrastructure that's already out of compliance with Corps regulations.
"When you live in places like Louisiana, you always have to be optimistic or you just don't fight," Malek-Wiley said.
Texas-based Energy Transfer Partners, which also built the Dakota Access Pipeline, didn't respond to requests for comment. Supporters say the pipeline will support about 2,500 construction jobs and pump around $750 million into Louisiana's economy. They also argue that pipelines are the safest way to move oil—far less risky than carrying it by train, where a derailment could lead to a disastrous explosion and fire.
Critics, however, say the industry's safety and environmental record is terrible, citing more than 140 pipeline accidents in 2016, and an explosion in February that killed one worker and injured two others.
In the years since the Deepwater Horizon blowout fouled stretches of the Gulf Coast, environmentalists have stepped up their opposition to new exploration and infrastructure. They've protested and disrupted the Interior Department's offshore lease sales and are preparing for more protests against Bayou Bridge. They're hoping to tap into the experience of people who took part in the Standing Rock protests, said Anne Rolfes, director of the environmental group Louisiana Bucket Brigade.
"There are ordinary people here who were moved to go all the way up to North Dakota to experience that and they are very committed to doing that here," Rolfes said. "People from groups who were very involved up there are helping us figure this out."

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>
