Unearthing Optimism

Dan Lambe

Booking Overview

An interview-led environmental podcast focused on optimism, nature, sustainability, and practical responses to environmental challenges, featuring visionaries, experts, and community leaders. PR agencies could credibly pitch climate scientists, conservation and forestry leaders, urban resilience experts, sustainability innovators, and prominent environmental communicators; booking difficulty is high because recent guests include a major science communicator, a leading climate-resilience expert, and the 21st Chief of the U.S. Forest Service.
