I am what many call an “active retiree‘. I retired from a career job but not from being active in the world and helping it become better. I do virtual book clubs along with public speaking, and the book clubs are more like discussion groups virtually via “Zoom”—all as a labor of love to encourage […]Read more "Reading just may haunt us."
The severe, unprecedented weather associated with increasing concentrations of greenhouse gases in the atmosphere is more concerning every passing year. The recent record heat in the US Northwest made headline news for several days. Temperatures in Portland, Oregon, reached 116oF, higher than other cities in the US have ever reached, except Phoenix and Las Vegas. […]Read more "GREEN JUNCTION: The earth’s natural balances have been disrupted BY JULIE PELLER PH.D"
The reason we hear about semiconductors in the news is due to the shortage of semiconductor chips. Semiconductors are materials that have properties that are essential in most electronic devices. Silicon is the most widely used semiconductor. It is an element and is often produced by heating silicon dioxide (sand!) at very high temperatures, along […]Read more "GREEN JUNCTION: What resources from Mother Nature do you treasure and protect?

A recently reported study on the Midwest Corn Belt determined that nearly one-third of this farmland has lost its carbon-rich topsoil. Soil organic matter, the carbon-based portion of the soil, is a critical component of healthy soil. The loss has been primarily from hilltops and ridgelines and is a consequence of tillage erosion from repeated […]Read more "GREEN JUNCTION: do you know what is happening to the corn belt?

Ecosystem services is a term used to describe the ways nature provides materials and functions for the essence of life. The food we eat, the oxygen we breathe, the medicines we take, and so much more are only possible by the services provided via resources of the earth. Trees are an example of nature’s offerings. […]Read more "Green Junction: What Do Trees Do For Us? By Julie Peller Ph.D"
Green Junction The physical surroundings of the celebrated events of Christianity – the birth of Jesus and the death and resurrection of Jesus – are profoundly different today than in that time of human history. Our visions and celebrations of Christmas and Easter in the present day are complicated by secular and material influences. In […]Read more "Green Junction: Our Physical Surroundings by Julie Peller Ph.D."
Most people do not think much about their chemical exposures. We trust that industrial processes, air, and water quality are ensured safe by appropriate regulations. However, society has become more dependent on materials, devices, energy, and transportation, and as a result, we are exposed to more chemicals. What are the typical chemical exposures for people […]Read more "Green Junction: Do you think about Chemical Exposures? By Julie Peller Ph.D."
Green Junction Unusual weather events have become more common and generally are a result of the earth’s changing climate. The science of climate change is incredibly complex with extensive consequences, yet many want to describe it or deny it in very simplistic ways. The term global warming is defined by the United States Geological Survey (USGS) as […]Read more "Green Junction: Global Warming is Climate Change by Julie Peller Ph.D."
Coal ash constitutes one of the country’s major industrial waste products, according to the US EPA. Coal is a brownish-black or black sedimentary rock that took millions of years to form. Coal’s carbon and carbon-containing compounds burn well, which has made it a significant source of energy for society. The part of the coal that […]Read more "Coal Ash and the water you drink by Julie Peller Ph.D."
