The air you breathe

The March 6 edition of The Daily Reflector carried a column by Walter Williams in which most of the space is used to run through various historical cataclysms that failed to blow our planet apart — Krakatoa, the great earthquakes in Chile and Indonesia, and so on. He concludes that the Earth is not fragile and then finishes with an ad hominem attack on “environmentalists.”

I believe the readers need a little more information. The earth has an equatorial diameter of 7,926 miles. From the depths of the Mariana Trench to the top of Mount Everest is a total of 13 miles or 0.16 percent total variance from the diameter. Most life on earth is found in a 2-mile band or 0.03 percent of the diameter. The earth is basically a Q-ball with a microscopic biofilm on its surface. Into this biofilm we are spewing an incomprehensible amount of carbon dioxide. Instead of a punctate event, we are deliberately changing the air we breathe. Very different.

If you take a good mileage car, 30 mpg, and drive it 15,000 miles in a year, that equates to 500 gallons of gasoline. Gasoline weighs close to 9 pounds a gallo, so 4,500 pounds. Gasoline is almost entirely octane, C8H18, and complete oxidation produces 8 molecules of CO2 and triples the weight. So, multiply by 3 and divide by 2,000 pounds and your fuel-efficient car has pumped about 6.5 tons of CO2 into the air that you breathe. Multiply by 150 million vehicles in the U.S., same for Europe, same for China and India, same for the rest of the world, throw in planes, trains, trucks, power plants and the amount is beyond any comprehension.

The earth does have buffering systems. But, every chemist will tell you that any buffering system can be overwhelmed, and that is what we are doing to the microscopic biofilm that we live in. Pity that Mr. Williams continues to fail to understand what is happening.

Welcome to Greenville — a growing city with an extraordinarily diverse population of citizens, many of whom came here as immigrants. It’s good for you to know that institutions like Vidant Medical Center and East Carolina University have attracted such gifted persons and their families.…

I believe we should only spend what we take in. We should not keep giving the rich and the corporations more and more and more and hope the windfall trickles down.

I believe in sharing, and that if everyone brings just one dish to a covered dish dinner, there would be more than everyone could eat.…

Please listen to the news, read the papers, align yourselves with people who are engaged in politics... just stay abreast of the events in our state as relates to politics. Educate your family, friends and neighbors. Our political system in North Carolina is broken, and unfair district maps are the…

What does the mayor’s basement have to do with good government?

The traditional July break from meeting is a good time for the Greenville City Council to stop a bad practice—discussing the public’s business in afternoon “workshops” in a small conference room without…

“Today our divisions seem deeper than ever, maybe deeper than those that divided colonists from Britain or North from South. Red-faced anger spits at us daily.” Daily Reflector Editorial July 4, 2019.

Lawrence Watts, in July 4th’s Public Forum, challenged anyone to obtain and publish the "real numbers" of energy production by the Amazon Wind Farm in NC (near Elizabeth City). In 2018, according to windexchange.energy.gov, the production was more than 500,000 megawatt hours.

Watts asserted…

Regarding his letter to the Reflector on June 30, I don’t recall ever “having made [Milton Bland’s] acquaintance.” Perhaps Mr. Bland is simply too “bland” for one to remember. His comment that “ask[ed for] ... an unqualified favor ... Tinsley exudes a…

The Kiwanis Club of Golden K Greenville has completed this year’s Support of our Youth in the Pitt County Schools through distributing over 1,800 books to first-graders. This program started some 10 years ago and continues to grow.

As the ECU Board of Trustees approaches the date to elect its new leadership, I'm reminded how poor that leadership has been over the past 3-4 years. The university is now transitioning to a new interim chancellor and from losses based on poor decision-making. Before any returning board member gets…

Privately paid assisted living facilities are a booming business and getting bigger every day. They are advertised as senior communities with attractive architecture, fun activities and amenities galore. However, once you are familiar with this type of care, you become keenly aware of how much…
