GREEN JUNCTION: What resources from Mother Nature do you treasure and protect? 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 […]

“The world must find ways to decrease the releases of carbon dioxide” ~ Julie Peller Ph.D.

The world has been dependent on fossil fuels for energy mostly since the industrial revolution of the late 19th and early 20th centuries. Power-driven advances in the steel, electric, and automobile industries defined this era. In 1901, the concentration of carbon dioxide in the atmosphere was 296 parts per million (ppm). In 1800, it was 283 […]

Where less is better, where local and sustainable businesses are supported. By Julie Peller Ph.D.

The ways the natural world serves the human population are sometimes referred to as ecosystem services, led by clean water, air, and soil.  Rain forests and other areas of dense tree growth also provide ecological services and are part of the world’s natural capital.  Trees take in carbon dioxide and provide oxygen, among many other […]
