Paula J. Ehrlich, President & CEO of the E.O. Wilson Biodiversity Foundation
Paula J. Ehrlich, DVM, PhD, is President & CEO of the E.O. Wilson Biodiversity Foundation, whose mission is to reimagine the way we care for our planet through actionable scientific research that supports communities in their stewardship of biodiversity.
Dr. Ehrlich is also co-Founder of the Half-Earth Project and has led the development of the Half-Earth Project Map, a global, spatially-explicit, and taxonomically comprehensive map of species, which informs how well conserved places are protecting species and identifies priorities for future conservation. She is founder of Half-Earth Day, which brings together world-wide participants from across disciplines to share perspectives and thought leadership on how to achieve Half-Earth and ensure the health of our planet for future generations.
Dr. Ehrlich has over 30 years of strategic scientific management and research expertise, and diverse academic, non-profit, and corporate leadership experience. Her current work embodies the hopes of the greatest naturalist of our time, E.O. Wilson.
Sam Hunter, Natural Resources Monitor, Weenusk First Nation
Sam Hunter was born October 1965 at Hawley Lake, located on the southern shore of Hudson Bay, at Ontario’s far north. While growing up, he lived in tents, sod teepees, at his homelands which many term “trapline.” Today, Sam is currently building an energy efficient home, which will be cool in the summer, warm during the winter months. The new home will harness energy from the sun, wind and water. This is an essential element for the green economy concept.
Currently, Sam lives in the remote Cree community of Peawanuck, Ontario – in the middle of Polar Bear Provincial Park. He grew up in the wilderness and practises traditions regularly. Being in a remote community, he isn’t totally dependant on his survival skills, however, he chooses to live his life that way as that is what makes him happiest.
Sam has a lifetime of stories to tell, from being born in a tent to being dragged out of his tent by a polar bear. He was forced to attend residential school as a child, where he would later lose his brother. At the age of 14 he started taking tourists out to see polar bear, earning him the nickname “Polar Bear Guide”. So many stories that he usually tops the last one, each time he gets together with family and friends.
Sam mentors youth with trips to the wilderness and is very interested bringing in outside programming mentors to teach science, climate change, adaptations, and visual arts. Sam understands the benefits of mentoring young people. Stories of teens whose lives have been changed by a mentoring adult, is powerful.
Walter Jetz, Scientific Chair, E.O. Wilson Biodiversity Foundation
Walter Jetz, MSc, PhD is a Professor of Ecology and Evolutionary Biology and Adjunct Professor in the School of Forestry and the Environment at Yale University. Dr. Jetz is Director of the Yale Center for Biodiversity and Global Change, which links scientists, students and practitioners engaged in the environment, biological, informatics, policy or health aspects and implications of global biodiversity change. Dr. Jetz leads the Map of Life at Yale University, which utilizes geospatial species distribution data and analytics to guide where we have the best opportunity to conserve the most species.
Dr. Jetz’ work addresses patterns and mechanisms of changing biodiversity distribution and the resulting implications on conservation and environmental management. His research combines remote sensing, phylogenetic, functional, and spatiotemporal biodiversity data with new modeling approaches and informatics tools. Dr. Jetz is particularly interested in how environmental, ecological, and macroevolutionary mechanisms combine to determine the co-occurrence of species and the structure of species assemblages.
In addition to his work at Yale, Dr. Jetz chairs the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Task Group on Biodiversity Indicators and is Co-Lead of the GEO BON Working Group on Species Distributions. Dr. Jetz was previously a professor of biological sciences at the University of California San Diego. Dr. Jetz earned his MSc in Integrative Bioscience and PhD in Zoology from the University of Oxford.
Luke Kelly, Associate Professor in Quantitative Ecology, University of Melbourne
Luke is an Associate Professor in Quantitative Ecology at the University of Melbourne and leads teams working locally and internationally. He studies the dynamics of plant and animal populations, educates about biodiversity and human well-being, and collaborates with diverse stakeholders to prevent species extinction.
He has over a decade of experience generating research and knowledge to help conserve biodiversity. His expertise is in ecological and evolutionary dynamics, such as how land-use shapes animal habitats and whether plant populations can evolve through key traits to keep up with the rate of environmental change.
Luke has been invited to lead papers in high impact journals such as Science and Annual Review of Environment and Resources. His work has revealed that changes in fire patterns threaten 4,403 plant and animal species across the globe with extinction, and highlighted ways that knowledge and practice of fire can help to achieve the 17 Sustainable Development Goals adopted by the United Nations.
He has received numerous awards and fellowships for his interdisciplinary research, including a prestigious Woodward Medal in Science and Technology, a Centenary Fellowship at the University of Melbourne, and a three-year Victoria Fellowship where he was based in Spain at the Forest Science and Technology Centre of Catalonia.

Louie Psihoyos, Oscar-winning filmmaker, Executive Director, Oceanic Preservation Society (OPS), National Geographic Photographer, and Founder of Projecting Change
Louie Psihoyos is an Academy Award-winning filmmaker and Executive Director of the Oceanic Preservation Society (OPS). He is recognized as one of the top still photographers in the world, having created iconic images for National Geographic for 18 years, and hundreds of covers for other magazines. Believing that film can be the most powerful weapon in the world, Louie founded OPS with Silicon Valley entrepreneur Jim Clark in 2005.
An ardent diver and dive photographer, Psihoyos’ mission is to show the world the decline of the oceans–our planet’s most crucial resource. Circling the globe dozens of times on photographic missions, he collects the imagery and stories underlying the compelling issues that challenge and threaten the natural world while connecting with environmentalists who are working to save the planet.
Psihoyos’ first documentary film, The Cove, won the Academy Award for Best Documentary Film of 2009 and over 75 other awards around the world. An annual dolphin hunt in a secret cove in Taiji, Japan suggests a microcosm of a larger picture: man’s disregard for the planet. The film garnered immense critical praise and has been seen by millions of viewers worldwide.
His second film, Racing Extinction, follows a team of artists and activists as they expose the hidden world of extinction with never-before-seen images. The film premiered on Discovery in 220 countries and territories on the same day, was nominated for an Emmy (Exceptional Merit in Documentary Filmmaking) and an Academy-Award (Best Song), and sparked the #StartWith1Thing movement. With partner Obscura Digital, Psihoyos was the creative mind behind the unprecedented large-scale video projections of endangered species onto the United Nations Headquarters, Empire State Building, and the Vatican.
Psihoyos most recently finished directing The Game Changers, executive produced by James Cameron. The film tells the story of James Wilks — an elite special forces trainer and winner of The Ultimate Fighter — as he travels the world on a quest for the truth behind the world’s most dangerous myth: that meat is necessary for protein, strength and optimal health. What James discovers permanently changes his relationship with food and his definition of true strength.
Through the production of compelling film and imagery underlined by moving narratives, contemporary crises, and heroic film subjects, Louie Psihoyos is radically changing how people perceive documentaries.
