The Dirt on Composting

Composting for Human, Soil and Climate Health  (start time: 4:39) It’s late spring, when many people are out gardening, planting vegetables, and spreading compost on the soil to give those veggies a leg up. Composting also benefits the planet.  If dumped into landfills, organic waste breaks down and releases methane, a greenhouse gas far more potent, if shorter-lasting, than carbon dioxide at trapping heat in the atmosphere. Municipal solid waste landfills are a major source of methane emissions. On this week’s show, host Susan Moran talks with two experts about the climate, ecological and human health benefits of composting, and some roadblocks to increasing the low rates of composting in the U.S., including Colorado.  Dan Matsch is the director of the Compost Department at Eco-Cycle in Boulder. He had been a commercial organic farmer for many years. Mark Easter is an ecologist focusing on the  carbon footprint of food and fiber. He worked for many years as a research research associate at Colorado State University. And Mark is the author of the forthcoming book The Blue Plate: A Food Lover’s Guide to Climate Chaos (September 2024, Patagonia).

Historical Analysis of Agriculture and Greenhouse Gases

Adler_Cowk1223-19-e1438626342444When it comes to reducing greenhouses gases, every little bit helps, and that includes managing the greenhouse gases produced by how we grow our food.  Raising livestock and growing crops both generate greenhouse gases, and to gauge their impact, a new study takes the long range view.  The results were published in a paper: “Measuring and mitigating agricultural greenhouse gas production in the U.S. Great Plains, 1870-2000” in the Proceedings of the National Academy of Sciences.  It analyzes 100 years of agricultural production, and it takes this look at farming close to home – it focuses on the bread basket of the United States – the Great Plains, which includes eastern Colorado.  Here to tell us more are scientists Myron Guttman (University of Colorado) and Bill Parton (Colorado State University)

China’s environmental impact // 100 Year Starship

Today, June 18, we offer two features interviews:
Feature #1 – China’s Environmental Impact (start time  4:46): China’s meteoric economic rise is causing harmful side effects, ranging from choking air pollution domestically to threatened forests, wildlife and air quality around the globe. Of course China’s per capita greenhouse gas emissions still pale in comparison to those in the United States, and roughly one-third of China’s CO2 emissions are generated to manufacture goods that are exported to the U.S. and other nations.  Craig Simons, a former journalist and author of a recently published book, The Devouring Dragon: How China’s Rise Threatens Our Natural World, discusses with co-host Susan Moran these critical issues, including coal mining in Colorado for export to China.

 

Feature #2 – 100 Year Starship (start time 15:35): Science and exploration tend to be long-term commitments. That’s well-known by fans of the “Hitchhiker’s Guide to The Galaxy” series, where the computer Deep Thought did calculations for 7.5 million years to find the answer to The Ultimate Question of Life, the Universe, and everything.  However, projects on our world tend to be limited by shorter-term political and funding cycles.  So it is hard enough to consider projects that require thinking a decade into the future, beyond many political lifetimes.  What about projects that require thinking a century or more into the future, many generations from now?  Well, that is exactly what one group of space exploration advocates is working toward.  The project is called the 100 Year Starship, which aims to create a long-duration mission sending humans to another star. Alires Almon, member of the project, talks with co-host Joel Parker about the challenges and the vision of 100 Year Starship.
