Paul Spittler joined Nell Larson and Chris Cherniak in the first segment of the show to discuss BLM plans to allow drilling and mining activities within the Desolation Canyon area of Utah.

In her new book,  Dirt: A Love Story, Barbara Richardson, an award-winning author who lives in Kamas, discusses the book and an open house she is helping to host in Kamas.


August 5th, the EPA and its contractors working at the Gold King Mine in southeast Colorado accidentally released millions of gallons of mine waste into the Animas River above the resort town of Durango. The plume of metal and mud stretched over 100 miles and three states before slowly diluting within the San Juan River in southeastern Utah.


It's the second day of the Birthday Pledge drive at KPCW, and we appreciate all your participation.  Today, along with soliciting pledges for KPCW's35th Birthday celebration, hosts Chris Cherniak and Nell Larson speak with Chad Ambrose from Rocky Mountain Power. The discussion covered areas of conservation of electricity and what's new at Rocky Mountain Power.


Author Joel Bourne joins Chris Cherniak and Nell Larson in the first segment of the show. In his book, The End of Plenty - The Race to Feed a Crowded World, Bourne chronicles the trends, making it likely we'll see more hunger and malnutrition in coming decades.  While the earth's population and economies are growing rapidly, our ability to feed it is undermined by climate change, growing water shortages, the use of farmland to grow biofuels and the increasing consumption of meat, which is a highly inefficient way to use the grain we grow.

Chris and Nell First speak with Rob DuBruc, staff attorney with Western Resource Advocates, regarding their efforts to have U.S. Oil Sands perform air and groundwater monitoring as a proposed strip mining operation in eastern Utah.  Then, on the second half of the show, they speak with Jenna Walenga of the research group Adventures and Scientists for Conservation.  ASC  is conducting research which documents the increasing extent and amounts of micro plastics showing up in fresh and saltwater around the globe.

On this episode, hosts Nell Larson and Chris Cherniak spoke first with Matt Pacenza,  Executive Director of HEAL Utah.  Matt talked about Energy Solutions plans  to accept depleted uranium at it's facility in Clive, Utah.  He also discussed why a proposed bill to weaken state-defined building codes  would result in the construction of homes with poor energy efficiency. In the second part of the show, Benjamin Skolnick with the American Bird Conservancy talked about the benefits of purchasing shade-grown coffee will have on not just birds, but ecosystems as a whole.

Michal Biskup

This week, KPCW is proud to announce that Michal Biskup is the winner of the KPCW Water Waste Contest.

Twelve-year-old Michal found his entry while on his way to a school sport:

"I took this photo while I was biking to soccer practice, when I passed Ecker Hill Middle School, I noticed that the sprinklers were set up so that they watered the concrete more than the grass. this is a problem because less water got to the plants and more got to the concrete, where it would evaporate or go into a sewer.

On this episode, hosts Nell Larson and Chris Cherniak spoke with Insa Repien, Executive Director at Recycle Utah.  Insa reflects on Recycle Utah's twenty five years of providing recycling and re-purposing services to the community and what challenges lie ahead. Next up, a conversation with Paul Spitler of the Wilderness Society about the deadline looming for the Land and Water Conservation Fund, and what will happen if the fund is not reauthorized by Congress.

On this episode, hosts Chris Cherniak and Nell Larson were joined by Professor Randall Wilson of Gettysburg College for a conversation about the formation and management of our public lands, including conflicts between privatization, regulation and environmental protection. Professor Wilson is the author of America's Public Lands - Yellowstone to Smokey The Bear and Beyond.
