About Unearthing Optimism
From the Arbor Day Foundation, Unearthing Optimism brings you into the heart of a new kind of conversation about the future of our planet — one rooted in hope, resilience, and the lessons nature offers. In each episode, Arbor Day Foundation CEO Dan Lambe uncovers fresh perspectives and real-world stories about enduring optimism in the face of environmental challenges. Through conversations with visionaries, experts, and community leaders, we explore how nature, and the people who champion it, can strengthen communities, and foster a more sustainable, vibrant future. Join us as we find beauty, wisdom, and solutions in the environment around us. We're not just imagining a better world, we're growing one.
