Who We Are

Mission & History

Our Mission

Earth Overshoot's mission is to make ecological limits central to all personal and public decision-making through targeted education and advocacy. Only then can we achieve a sustainable society characterized by human well-being and flourishing biodiversity.


Our History

Earth Overshoot builds upon the key messages in 8 Billion Angels, a documentary feature film produced by Executive Director Terry Spahr about unsustainable population growth as a primary driver of our world's environmental emergencies. 

The film is a critical component of Earth Overshoot’s multi-tiered approach to raising awareness and normalizing the discussion about the catastrophic impact our unsustainable population growth and consumption are having on our planet and the steps we can take collectively and individually to solve the problem.
