At Adamah, we inspire and empower people to feel and act on the deep connection between people and planet.
We build community and cultivate a more sustainable future through immersive experiences, inspiring programs, and collective action. In this moment, we must be the bridge between our ancestors and our descendants, mobilizing the power of the Jewish people to respond to the existential crises of our time.
We cultivate vibrant Jewish life in deep connection with the Earth, catalyzing culture change and systemic change through Jewish Environmental Education, Immersive Retreats, and Climate Action.
Our Values
We cultivate connections We learn from the Earth We take care of each other We educate through experience And, if not now — when?
