EarthSayers, the Voices of Sustainability, advances sustainability leaders and citizens primarily through video aggregation from across the Internet - those speaking on behalf of Mother Earth and her children. Earthsayers are the voices of experts, business leaders, scientists, teachers, children, wisdom keepers, and citizens from all walks of life. Each of the 1,800 plus programs has been curated for relevancy and quality. Each has been categorized using a taxonomy developed specifically for sustainability to impact page results on major keywords and phrases such as global warming, transforming our economy, indigenous knowledge, culture and consciousness, equality for women and girls, Plastic in our Oceans, and one water.

Ruth Ann Barrett

Ruth Ann is the founder, producer, and curator of EarthSayers, the voices of sustainability, a specialized search engine. EarthSayers was launched on August 1, 2008, in San Francisco, California.  A redesign in August 2020 as earthayers.com simplifies access to the database of over 4,000 voices of sustainability. In 2023 Ruth Ann became the administrator of the EarthSayers Fund, a charitable giving program made possible through the Estate of her brother, Ray Edward Barrett, that emphasizes small grants to front-line organizations serving Mother Earth and her children.

JoAnne O'Brien-Levin, Ph.D

Dr. JoAnne O'Brien-Levin is a communicator, a natural collaborator, and the creator (2007) of the EarthSayers.tv sustainability taxonomy.

JoAnne likes to break new ground. In her early career, she was a pioneer in interactive instructional design, winning national awards. She co-designed and produced “Decision Point,” a management training simulation featured in Psychology Today. 

Subsequently, she was a founding member of the Society for Organizational Learning (SOL) at the Massachusetts Institute for Technology where she helped pioneer learning history methodology. Excerpts of her work were published in The Dance of Change: The Challenge of Sustaining Momentum in Learning Organizations by Peter Senge et al. (Doubleday, 1999). She also co-authored, with two business executives, The Power of Collaborative Leadership (Butterworth Heinemann, 2000), a book that examines organizational change efforts from the inside-out.

JoAnne has a long-standing interest in indigenous peoples and indigenous ways of knowing. She has studied with a variety of Native teachers, collaborating with one to co-author a second book, Business Revolution through Ancestral Wisdom (Outskirts, 2008). She later served on the Board of the SEED Institute in Albuquerque, NM, which conducted annual dialogues between Native Elders and Western scientists to explore how new discoveries in the field of quantum physics were, at last, bringing the Western scientific worldview into alignment with ancient indigenous understandings. In addition, she helped establish Centro Sacha Warmi, a nonprofit supporting the preservation of traditional indigenous knowledge in the Ecuadorian Amazon.

Currently, JoAnne (writetowisdom.com) works as a writing collaborator, coach, and editor, helping to shepherd new books into being, specializing in thoughtful non-fiction. Two of her clients have won Silver Nautilus awards. 

JoAnne holds a BA in Sociology from Anna Maria College for Women, an M.Ed. from Boston University, and a Ph.D. from the Annenberg School for Communication, University of Southern California (USC). She lives in Santa Fe, NM.
