Yes, we have problems. Some are monumental. But we also have people all over the world working to solve these problems. They're out and about and in laboratories doing research, learning what's wrong with the environment and how to fix it. They're scientists and technologists and everyday people on a mission. The articles in this blog focus on the discoveries and inventions that provide a better way to live and improve the quality of life for all inhabitants. The content is good news for Planet Earth.

I just had to grab this link and share it. Maya Lin, who created the powerful Vietnam War Memorial --  the one that brings nearly all its visitors to tears --  has created a memorial to the species of the planet. Hover your mouse over some of the dots on the map and you can get lost to in the song of humbpack whales or migrating birds. Lin's digital memorial conjures up feelings of compassion for threatened species around the world. http://whatismissing.net/#/home

Clearing The Air

Perhaps you've heard of Ozone Falls,Tennessee, a "wide place in the road" on US-70 where a gorgeous, 110-ft falls plunges over the edge of the eroded stream bed. Now preserved as a state natural area, the falls and a roadside tavern were once a stop-over for travelers. Here, they could rest and reinvigorate themselves, breathing in the fresh, clean air generated by the falls. But wait. Ozone Falls? What was that EPA slogan? Good Up High, Bad Nearby?

Oxygen (O2) becomes ozone (O3) when oxygen atoms pass through fast-moving water or come in contact with an electric spark, such as in waterfalls and thunderstorms. Part of that fresh, clean odor that one often smells near a waterfall and after a storm is ozone. But the ozone during these instances is minute and very temporary. It is harmless in these instances. In fact, ozone is produced artificially for use as a powerful disinfectant in industry and utilities, for wastewater treatment, and in potable water treatment. It kills bacteria, molds, and even viruses, great for the bugs but no so great for us.Whether ozone in the tiny amounts near waterfalls has healthful, invigorating benefits is not scientifically known.

Clean air is achievable.

Ground-level ozone is just one of the evils of fossil fuel emissions, but The American Lung Association considers it to be the most dangerous. So how do we begin to get this harmful substance out of our air and our lungs?

When we talk of air pollution in East Tennessee, we have two choices: we can do something or we can do nothing. Oversimplified, perhaps, but that’s how Jonathan Overly, director of the East Tennessee Clean Fuels Coalition (ETCFC) sums up our roles in this growing concern.

“Yes, we need policies that protect our health and the health of the environment, but not having adequate policies in place doesn’t excuse us from doing what we can,” Overly says. “We all need to be Actors for Change.”
He has a real problem with foreign oil and, steeped in the economics of growing biofuels such as switch grass, feels it’s downright un-American to not support their use. “Why wouldn’t we put money back into America?” he asks.

Overly works largely with fleet managers in helping them understand and gain access to conversion to biofuels. If he can target those persons who have the say-so over what kind of fuels they’ll use in their fleets, he has a broader reach.

Some fleets, like Knoxville Area Transit (KAT) have already made the switch to biofuels In and have an active bus system running throughout the city to get people to their destinations, leaving the car home; and you might note that none of the buses are billowing black smoke.

In 2009, Overly was appointed Principle Investigator (PI) of an $800,000 grant from the Department of Energy to make I-75 in Tennessee an E85/B20 corridor, meaning a pump for one of these fuels will be installed at exits no more than 200 miles apart. The project covers the entire length of I-75, from Sault Ste. Marie, Minn. to Miami, Fla. at a cost of 1.8 million. Overly will coordinate the Tennessee portion.

Since Tennessee is not following suit with a few other states that have mandated every filling station to have biofuels pumps (Minnesota takes the lead), establishing biofuels pumps along I-75 will be the least we can do.

Then on September 16, 2009, the EPA announced that it would reconsider the 2008 national ambient air quality standards for ground-level ozone, based on its own panel of science advisers that say the 2008 standards don’t offer enough protection for human and environmental health. The EPA will offer its final recommendations in December 2009.

Once these recommendations are finally established, whether changed or not, states will be required to submit plans for implementation of clean-up by December 2013. How fast any action takes place is anybody’s guess.

What else can we do? Be mindful. Think about everything you do that uses energy. Imagine that the on and off switch for the lights, washer and dryer, water heater, and dishwasher are all directly connected to TVA’s coal-burning demands. Be mindful of the gasoline you burn, whether it’s in your car, lawn mower or leaf blower and how you can use less. Be resourceful and thoughtful.

“Starter steps,” Overly calls them. “We need to take starter steps.”

The Tale of Two Ozones


  Unless you just landed on the planet, you’re aware of the ozone hole above Antarctica. When scientists discovered it in the mid 1980s, they were alarmed that we had a very serious problem on our hands.
The ozone layer was being depleted. This layer of atmospheric gas absorbed the sun’s ultraviolet rays and prevented every living thing on earth from – well, frying. The culprits were chlorofluorocarbons (CFCs), the coolant in cars, refrigerators, and air conditioners and propellants in aerosols. Researchers scrambled to come up with suitable replacements, and, through international agreement, CFCs have steadily been replaced with less harmful refrigerants and propellants.
We came close to doing some really harmful damage. But, because the world’s scientists knew how to stop the depletion and were able to convince the planet’s leaders to take action, the hole is slowly diminishing. Thinking back, it was amazing that we were able to achieve such solidarity.

Beaver Creek in the News

Many apologies for the long delay.  However, while posts were absent from this blog, the work in the Beaver Creek watershed has progressed.

I stumbled across two recent News Sentinel articles that speak volumes about public understanding of science and how a lack of it -- particularly among the voting population -- can be detrimental to the environment. The August 22 article explains briefly why a naturally meandering stream supports wildlife far better than one that is is straightened by roaring stormwater laden with sediment -- further facilitated, as in this case, by the Civilian Conservation Corps. 

An interesting article, no doubt, but even more interesting are the 50-plus comments following the story. More than one person fails to connect the value of Beaver Creek to the quality of wild and human life but is able to link work done on the creek to wasteful government spending. The discussion becomes one of paranoid political views rather than the critical state of natural resources.

About two weeks later on September 3, a News Sentinel contributor writes fondly of his days fishing in Beaver Creek. He memorializes the creek as it was when he was a boy, its banks steadied by the roots of an old oak tree. Among those roots he found bluegill seemingly just waiting for the worms to drop down into their watery world.

One story brings comments from readers who mock what they perceive as the futility of rehabilitating Beaver Creek. The other one reminds us just why we need it.

Beaver Creek -- from Ruin to Rehabilitation, Part 3

Green Infrastructure is Basis of Smart Growth

Note: The first three articles of this blog tell the story --12 years in the making -- of how a stream is making a comeback. The residents who live in the Beaver Creek watershed, about two dozen government agencies and community organizations, and a variety of scientists are bringing the degraded stream back to life. The Beaver Creek story shows what people can do when armed with both knowledge and know-how. 

Village life has attractive attributes.
There’s something to be said for the ways of the past. With the hurried development that’s occurred in the last several decades, we may have forgotten about the beneficial aspects of small town life – the ease with which we could walk to the neighborhood deli for lunch, pick up a prescription at the pharmacy and purchase some locally grown fruits and vegetables at a produce stand.

People Pitch in to Turn the Tide of Beaver Creek

The power of stakeholders and partnerships.
In a watershed, whatever is done to the stream is done to the place you call home. You either enjoy a pristine setting or you can endure an ugly, muddy mess. You have a stake in the condition of the stream.
