Kgnu - How On Earth

Rock Arch Stability (Starts 5:24) How on Earth's Daniel Strain  talks to Jeffrey Moore, a geologist who studies the West’s iconic rock arches — and watches them for signs that they’re about to collapse.   Neonicotinoids and Silent Spring - (Starts 15:33) We share a story from H2O radio warning about a pesticide that’s linked to the collapse of honeybee colonies, and growing concerns that it’s dangerous for other forms of life, it's persistent in the environment and might bring about a new Silent Spring.  This information will be part of this week's Western Apicultural Society conference in Boulder.   Hosts: Shelley Schlender and Daniel Strain Producer: Shelley Schlender Engineer: Shelley Schlender Executive Producer: Susan Moran Listen to the show:
