Everybody has a story about the natural environment. Look around, and into yourself.

University of Tennessee journalism professor Mark Littmann asks students in his environmental writing class every semester to write short sketches about environmental issues they may observe during any given day. Such an assignment requires an almost poetical approach. Here's a sampling from spring semester.

A reef of bones

Huge schools of rainbow-colored fish weave through the brightly colored corals as Sir David Attenborough describes a day in the life of a fish on the television screen. A little girl is mesmerized; this is no Disney fantasy but real life. The nature shows on Animal Planet capture her imagination and soon mornings and afternoons are spent watching big cats and meerkats navigate the wild spaces they call home. She finds an instant favorite in the book “The Rainbow Fish” and celebrates turning four with a sparkly rainbow fish cake, hand decorated with sprees for rainbow scales. She insists someday she will swim among the fish in their magical undersea world.

Climate bill designates TVA as a potential recipient of clean energy investments and loans

KNOXVILLE — Clean-energy advocates are urging the Tennessee Valley Authority to use funds provided through the Inflation Reduction Act to deliver environmentally friendly energy to Tennessee customers. 

The massive bill Congress passed Friday includes $370 billion for clean energy investments and listed TVA as an entity that is eligible to take advantage of clean energy credits and loans to significantly reduce the cost of energy-efficient infrastructure. 

On Aug. 12, the Clean Up TVA Coalition, including the Sierra Club, the Southern Alliance for Clean Energy and Appalachian Voices, urged TVA to take advantage of the legislation and make funds available to its affiliated local power companies, which can then offer energy-efficient options for customers.

Smokies parking fees will generate $7 million in revenue for park infrastructure

GATLINBURG — Getting outside just got more expensive.

Great Smoky Mountains National Park officials announced Monday the park would proceed with plans for a $5/per day parking pass required of all cars staying in one spot for more than 15 minutes.

Weekly passes will be $15, and annual passes will be available for $40, according to a release from the park service. Fees will also increase $3 for backcountry and campground permits, meaning campers and backpackers will have to fork over $8 a night.

Dramatic monarch declines mean the bell tolls for we

KNOXVILLE — Monarch butterflies are ephemeral by nature. The orange and black dalliances that flitter through our lives, our yards, and our countryside like motes of dust are here one minute and gone the next. We pause for a few seconds to watch the “flutter-bys” and then move on.

For about all of the Lepidopteran family, where they come from, where they go, their raison d'être, we don’t ask. They are winged wisps that pass through our busy lives. But that is not true with this orange and black butterfly, named to honor King William III of England, the Prince of Orange. But two people did ask.

Norah and Fred Urquhart lived in Southern Canada and in the late 1930s they noticed that the monarch butterflies seemed to all be fluttering south this time of the year. Could they possibly be migrating and if so, where did they go? The notion that a butterfly might migrate south for the winter seemed hard to fathom. Yes, broad-winged hawks migrate. But a flimsy butterfly?

Discovery of ancient ambush predator is one of few large carnivores found at East Tennessee paleontological site

JOHNSON CITY — Overseen by the Don Sundquist Center of Excellence in Paleontology at East Tennessee State University, researchers have studied the Gray Fossil Site for over 20 years. They have identified many extinct animal and plant species of the Pliocene epoch that lived there some 5 million years ago. While large herbivores are well known from the site, large predators are relatively uncommon, so far including only alligators and scarce remains of at least one sabertooth cat. 

Now, there’s a new predator on the scene.  

A recent study published in the Journal of Paleontology describes a single right humerus (upper arm bone) of an animal named Borophagus, a member of an extinct group more commonly called bone-crushing dogs. The animal is so named for its powerful teeth and jaws. This is the first evidence of any animals in the dog family from the Gray Fossil Site.

The research was conducted by Emily Bōgner, a doctoral student at the University of California, Berkeley, and alumnus of ETSU’s paleontology master’s program, and Dr. Joshua Samuels, associate professor in the ETSU Department of Geosciences and curator at the Gray Fossil Site and Museum.
