Earth Day is every day, but it’s officially on Friday, April 22 this year. Get involved.

The 2022 observance of Earth Day is officially Friday, April 22, but the Knoxville area plans celebrations, work parties and seminars in honor of the 50-year-old annual recognition of Mother Nature through Saturday. Here’s a quick look at some local ways to love your mama. This list will be updated.

New York Times: Ukraine environmental holocaust just the latest in ways war scars the Earth

Open armed conflict understandably abrogates immediate concerns about the natural environment.

Despite the tens of thousands of human deaths already caused by Russia’s invasion of Ukraine, the war’s impact on natural systems can’t be understated.

In some cases, Russian troops have taken up positions in natural parks and protected ecological areas in Ukraine. The Black Sea coast is an important remaining area of biodiversity in Europe. Ukrainian counterattacks, while understandable, have also inflamed environmental consequences.

There are also immediate risks to human respiratory health from the fires sparked by attacks on fuel depots and chemical facilities.

War’s negative environmental impacts are by no means a new thing: See the use of Agent Orange by the U.S. in Vietnam and the wasteland of burning oil fields left behind in the Gulf War.

War is bad for every living thing.

Sevier County Emergency Management Agency

Forest fire above Wears Valley in Sevier County nears full containment; Seymour fire under control

UPDATE APRIL 4: The Sevier County Emergency Management Agency said the Hatcher Mountain/Indigo Lane fire is largely extinguished. Fire crews continue to further subdue the Millstone Gap fire near the Sevier/Blount county line. 

The National Weather Service warns of continued high fire danger citing breezy winds and low humidity. Widespread rainfall is forecasted to fall beginning tomorrow.

Officials said the Hatcher Mountain fire ultimately burned 2,500 acres, and damaged or destroyed 300 structures.

UPDATE APRIL 1: Fire crews focusing on the stubborn Hatcher Mountain fire had to pivot in part early Friday to also fight a new wildfire in Seymour near the Blount and Sevier county lines.

Sevier County officials said the Wears Valley-area fire was 45-percent contained this afternoon following a significant brew-up late Thursday. At least 100 structures/dwellings had been “affected” by the fire, which has consumed at least 3,739 acres. Numerous rental cabins and homes have been lost.

New York Times: Evolving native predation may help stem invasion of Burmese python

The proliferation of the exotic and invasive Burmese python in the swamps and wilds of Florida is demonstrably bad for native birds and mammals.

Researchers now have evidence the best solution might have been there all along.

A bobcat was captured on a trail camera by the U.S. Geological Survey eating python eggs and challenging one of the gigantic snakes. It was the first instance of natural, native predation on the snake’s eggs. Bobcats are already known to target reptile eggs, including those of sea turtles.

“While it is possible that this interaction was just an isolated incident, it is also possible that native species are beginning to respond to the presence of the python,” the New York Times reported.

“‘Most cat species adapt their diet to what is available, so bobcats predating on python eggs is actually not that surprising’” said Mathias Tobler, a wildlife ecologist at the San Diego Zoo Wildlife Alliance.”

Local installment of worldwide virtual Climate Teach-In is set for 2:30 p.m. March 30

JEFFERSON CITY — Brian Sohn had “the closest thing to a panic attack” when his second daughter was born.

He had long been alarmed by climate change and its potentially disastrous effects, but her arrival brought home the need to address the environmental challenges of a rapidly changing planet.

So now the Carson-Newman University education professor is putting some final touches on a virtual climate-related “teach-in” he’ll host from 2:30 to 3:30 p.m. Wednesday, March 30.

Dead hemlocks are seen along Parson Branch Road near Cades Cove. National Park Service

CADES COVE — Great Smoky Mountains National Park contractors began removing at least 800 dead hemlock trees along Parson Branch Road, an eight-mile primitive backcountry road that connects Cades Cove with U.S. 129 on the western edge of the park.

The road has been closed since 2016 because of the tree hazards and damage to the road surface. The hemlocks succumbed to the hemlock woolly adelgid, an exotic insect that has wreaked havoc on hemlock stands and their accompanying ecosystems.

The road passes several trailheads, and is used by emergency vehicles as needed. The park initially identified some 1,700 trees that posed a hazard to the adjacent roadway, but that number has naturally declined by about half over the past six years.

Friends of Great Smoky Mountains National Park provided $100,000 for the hazard-mitigation project. That was matched with $50,000 from the federal government.

Once the dead trees are removed, work will begin to rehabilitate the roadway and ensure its safety. 

The roadway could reopen this summer, according to a news release from the National Park Service.

The Tennessee Aquarium IMAX Theater in Chattanooga premiered its new 3D educational movie Ocean Odyssey on March 4.

Author,  oceanographer and National Geographic Explorer-in-Residence Sylvia Earle visited the aquarium to help launch the movie, which she and Rupert Degas narrate.

The movie follows a humpback whale mother and calf as they navigate the East Australian Current from the Great Barrier Reef to Antarctica. The planet’s oceans are home to the most diverse and abundant array of life on earth, but they are threatened by climate change, pollution and acidification. Still, life lives on.

The Tennessee Aquarium encourages filmgoers to enhance the 3D film experience with a visit to the Secret Reef exhibit in their Ocean Journey building. This exhibit replicates the Flower Garden Banks off the coast of Texas and Louisiana. 

In 1990, Dr. Sylvia Earle became the first woman appointed chief scientist at the National Oceanic and Atmospheric Administration.  

She left that agency to work in the private sector to promote healthy oceans and public access to ocean environments, including Mission Blue.
