Our mission is to share the spiritual wonders of water and the Sea from a Jewish perspective, and raise awareness and encourage action to address the many threats facing the Marine Environment.

We envision a world where the ocean is clean, where marine life is abundant and safe, and where the sanctity of the Sea is appreciated and protected.

"You are not obligated to complete the work, but neither are you free to desist from it."

- Rabbi Tarfon
