This Green Earth is a weekly, hour-long program that focuses on the environment and environmentalism. Co-hosts Christopher Cherniak and Nell Larson explore the science, politics, economics and ethics behind the environment, natural resources, and sustainability.

The program includes interviews with local and national experts in the fields of water resources, air quality, environmental policy, fossil and renewable fuels, climate, conservation, ecosystems, agriculture, aquaculture, and sustainability.

TGE has interviewed a number of individuals from different environmental fields including: writers Andrew Revkin, Terry Tempest Williams, Craig Childs, Richard Louv and Paul Erlich; politicians like the Mayors of Park City and Salt Lake City; policy analysts from the Natural Resources Defense Council and the Environmental Defense Fund; scientists and researchers from the Monterey Bay Aquarium to the National Weather Service; and, local sustainable business owners from Copper Moose Farm, Main Street Olive Oil Company, Whole Foods Market, and Fairweather Natural Foods.

Christopher Cherniak is an environmental engineer with nearly 30 years experience as an environmental consultant. Nell Larson is an environmental scientist, educator, and a graduate of the Yale School of Forestry. Together, they direct This Green Earth's mission: to educate listeners about the importance of environmental preservation, conservation, and stewardship.
