Babies born today may be unable to procreate without medical technology
Written by EarthSolidarity!™The Guardian: Interview of Shanna Swan. 'Most couples may have to use assisted reproduction by 2045'
In her new book,“Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race,” Shanna H Swan, professor of environmental medicine and public health at Mount Sinai School of Medicine in New York City, provides more evidence how the wide use of plastics and other materials containing hormone-mimicking chemicals interfere with fertility and fecundity.
She advises how one may at least reduce exposure to these substances, to some degree, by making informed purchase decisions, such as avoiding processed food.
Knowledge particularly important for pregnant women!

The photovoltaic (PV) solar panels most commonly used for commercial applications today have an efficiency in the range of 16 to 22 percent. On the lower side of this range, one finds less-expensive panels, mostly made with poly-crystalline solar cells, while monocrystalline cells dominate the upper side.
The highest-efficiency panel presently on the market is SunPower’s A-Series residential panel, with a claimed 22.8 percent efficiency in converting photons to electrons under standard conditions. That's up just slightly by 0.73 percent from five years ago. Although many other manufacturers have caught up to offer panels rated at more than 21 percent, development progress of silicon-based monocrystalline PV toward the theoretical limit of around 30 percent has slowed to a crawl.
Over the same period, newer technologies for multijunction PV cells with thin subcell layers of gallium-arsenide and similar semiconductors, grown on top of silicon or perovskite crystalline materials, has been progressing rapidly and may be capable of exceeding 50 percent efficiency in the future. Lab results still require years of research and manufacturing development before panels come to market. Initially their high price will limit them to market niches where low-weight and small-surface per Watt will justify the cost, such as for aerospace applications or covering electric vehicle surfaces. The following links provide a good overview of such technologies and discuss their longer-term outlook.

Health officials: Knoxville air quality on sustained upswing
Written by Thomas FraserWBIR: Knoxville air quality data indicates sustained improvements
The Knox County Health Department reports that fine particles declined by half between 2007 and 2018. Ozone levels also remained below national standards during that period. The combined pollution reductions — achieved through tighter emissions standards on power plants and vehicles — have resulted in the cleanest air in Knox County since 1999, according to the Health Department.
Here’s a link to the full 2019 Knox County Community Health Assessment.

High-elevation trail plan proposed near Sylva
Written by Thomas FraserWLOS: Mountain property owners wary of trail network between Sylva and Cherokee
Proponents of a proposal to build a high-elevation 35-mile multi-use trail system in Jackson County said it could further fuel growth in the area’s outdoor-recreation industry.
Some people who already own homes and property in the area abutting, for instance, Pinnacle Park in Sylva, fear an influx of strangers who would jam roads trying to access public lands owned by Sylva and Cherokee. Shocker.
The Nantahala Area Southern Offroad Bicycle Association is putting together a concept plan. The group says it would be the highest (3,500 feet) such trail network in the eastern United States.
Bradford pears suck, and a South Carolina county is offering a bounty, dead or alive
Written by Thomas FraserWBIR: County bounty offered to rein in common nonnative landscaping trees
Confession: Your friendly neighborhood Hellbender Press editor bought a house for his family that featured rows of well-established Bradford pear trees. While they are not my favorite, are distinctly alien and should be made to leave this world, they provide an effective privacy screen. I’m sure many of you are in the same boat: Why eliminate healthy trees and expose your property? Let ’em ultimately die and rot, I guess. And plant natives elsewhere. WBIR also has suggestions for natives to replace Bradford pears.
Maybe we’ll figure it out, but in the meantime here’s a story about a South Carolina county offering a bounty on Bradfords.
Interestingly, WBIR has posted numerous, unflattering stories about Bradford pears over the last couple of years. Seems they have an editorial grudge. Good. Keep rolling with it.
Opponents race to stop proposed motorsports track in Oak Ridge
Written by Thomas FraserKNOX NEWS: Does a motorsports park make sense for Oak Ridge?
A Knoxville real estate developer and some officials maintain a motorsports park at the Horizon Center industrial park would create jobs, tax revenues and a destination for private high-performance vehicle enthusiasts in the region. Opponents lament possible noise and light pollution and the loss and fragmentation of healthy, diverse hardwood forest and open space set aside decades ago by DOE as an environmental preserve.
The municipal approval process has moved forward since this video was made, but here is a comprehensive argument from those who oppose the Oak Ridge motorsports park and would rather preserve the popular recreational and natural site on the far west end of Oak Ridge.
First Native American named to lead Department of the Interior
Written by Thomas FraserNYT: Interior Secretary first Native American to hold vital post
The Senate on March 16 confirmed the first Native American director of the U.S. Department of the Interior, Democratic U.S. Rep. Deb Haaland of New Mexico.
“… her new position is particularly redolent of history because the department she now leads has spent much of its history abusing or neglecting America’s Indigenous people.
“Beyond the Interior Department’s responsibility for the well-being of the nation’s 1.9 million Native people, it oversees about 500 million acres of public land, federal waters off the United States coastline, a huge system of dams and reservoirs across the Western United States and the protection of thousands of endangered species.”
Tennessee journalists wary of amendments to public meeting laws
Written by Thomas FraserETSPJ: Hold up on Covid-era meeting law changes to ensure public accommodation
Hellbender Press takes a fundamentalist attitude when it comes to the First Amendment and unimpeded public access to information from the government and its decision-making processes. The East Tennessee Society of Professional Journalists released a statement March 12 regarding public access problems with an otherwise reasonable amendment to the state open-meetings laws. The amendments were introduced at the request of the Knox County Commission, according to ETSPJ.
Here is the press release from ETSPJ in its entirety:
“The East Tennessee Society of Professional Journalists opposes a bill sponsored by two Knoxville lawmakers, Rep. David Wright and Sen. Richard Briggs, that would create yet another exemption to the state Open Meetings Act.
The bill, apparently introduced at the request of the Knox County Commission, would allow almost half the members of a county legislative body to participate in meetings by telephone or other electronic means. For Knox County, this would mean four of the nine commissioners; for Davidson Metro Council with 40 members, 19 of them could conceivably participate by telephone.
The rationale for the bill is laudable in that so long as a quorum is physically present in a single location, it permits an otherwise absent member to attend and represent constituents. Acceptable reasons for absence are family or medical emergencies, military service or out-of- the-county work.
Its shortcoming, however, is the total lack of public accommodation. As currently drafted, this bill would be an exception to a section of Tennessee law that permits such electronic participation so long as all conversation is audible to the public, each member can simultaneously hear and speak to each other during the meeting and all votes are taken by roll call.”
The requirements in the existing Tennessee law are similar to those in the governor’s emergency executive order for public meetings during the pandemic, but the Briggs-Wright bill would incorporate the convenience of the pandemic order for government officials without any of the public safeguards.
Tennessee school boards received an exemption in 2012 for electronic participation, but whether by happenstance or by local rule, the Knox County School Board has never had more than one member participate electronically at the same time. So, the public has not faced the obstacle of determining who is speaking or how members participating by telephone voted.
The exemption to existing law for school boards may have begun a slippery slope for multiple state governing bodies to carve out a permanent exemption in the state Open Meetings Act.
ETSPJ asks that lawmakers Briggs and Wright withdraw their bill or else amend it so that it incorporates public accommodations similar to those in the existing state law and the governor’s executive order for meetings during the pandemic.
Indigenous people could provide a path to global land and water preservation
Written by Thomas FraserNYT: Global effort under way to protect 30 percent of the world’s remaining natural areas
The “30x30” plan, led by Britain, Costa Rica and France, aims to preserve at least 30 percent of the Earth’s remaining natural terrestrial and aquatic habitats. A convention of dozens of nations in China later this year will outline and streamline possible methods to meet this goal. Some countries want to increase the goal to 50 percent.
One good reference point may be the lands controlled by indigenous people, who, research shows, do a remarkably good job of maintaining biodiversity in the native habitats in which they live. Their careful methods of resource extraction provide economic benefits while preserving the natural integrity of their native lands.
The U.S. is the only country aside from the Vatican to not agree to the convention’s goal, though President Joe Biden has floated a similar plan to preserve 30 percent of the country’s remaining natural areas.

Good piece here on a renewed threat to the Pigeon River, which threads from North Carolina into Tennessee. Your friendly neighborhood Hellbender Press editor was a raft guide there for a while — people loved to be on that river, and it is a true environmental and economic success story.
But after years of environmental improvements to the river and accompanying economic gains, the state of North Carolina is considering relaxing standards for a nearby paper mill’s pollutants.
The state is considering loosening the discharge standards for the paper mill’s current owner. A public hearing on the matter is set for April 14.

Right whale entangled in ropes and debris dies off Myrtle Beach
Written by Thomas FraserPost and Courier: Right whale meets sad end off Myrtle Beach
An endangered North Atlantic right whale monitored by researchers died off the northern South Carolina coast.
Right whales got their name from the fact they were the “right” whale to hunt. The species was almost hunted to extinction and its revival is faltering.
“Cottontail” was entangled in “ropes and other gear” and suffered its way from the Florida coast to Myrtle Beach, where it succumbed to its injuries.
Great white sharks reportedly fed on the carcass off the shore of the popular tourist destination.

UT professor pens book on origin of animal rights
Written by Thomas FraserDAILY TIMES: UT professor chronicles rise of animal rights movement
A University of Tennessee professor traces the origins of the animal rights movement in the 19th century U.S. in a new book, “A Traitor to His Species: Henry Bergh and the Birth of the Animal Rights Movement.”
Ernest Freeberg, head of the history department, chronicles how the action of one man who stopped the whipping of a trolley horse in New York City ultimately led to the modern animal welfare movement and the advent of laws punishing cruelty to animals.
Henry Bergh, who founded the Society for Prevention of Cruelty to Animals in 1866, was derided as an extremist and misanthrope by his contemporaries, but his philosophy and moral approach to animal welfare eventually became prevalent in American society.
200 wolves killed in Wisconsin after ESA restrictions are lifted
Written by Thomas FraserNYT: Gray wolf hunters sued state to move season up; first state wolf hunt since 2014 following delisting
Hunters killed 212 gray wolves during a three-day frenzy in Wisconsin after the gray wolf was removed from the Endangered Species List by the Trump administration.
State wildlife officials had wanted to delay the hunt until November so a science-based and fair game plan could be finalized. Wolf-hunting advocates sued to move the hunt up to last week; biologists and indigenous groups said they hunt occurred during breeding season, so the full effects on gray wolf populations could be far-reaching.
The state estimated there were about 1,200 wolves in Wisconsin prior to the hunt.

“Gas” stations will survive as electrons replace gasoline
Written by Thomas FraserBloomberg: Most traditional fueling stations will adapt and survive as electricity replaces gasoline
Bloomberg Climate Newsletter has an interesting take on what may become of traditional gas stations — and their associated retail services and employees — as fuel sources transition from gasoline to electricity.
There’s already a case in point: Norway, where gasoline use has peaked and the transportation economy is moving away from traditional fossil-fuel filling stations.
In short, there will still be demand and purpose for convenience stores in some areas, theyÆll just be selling a different type of fuel.
