Sustainable Habit Program
Cape Coast Ghana
Earth Bag Seed Bank Project in partnership with Adamah Ver Zerah
Low Cost Building Research Trip to Ghana – June 2025-2026
Members of the Sustainable Habit Program will be on site for 4-6 months as the last stage before the “Build” faze goes into effect. This program needs more support in the form of members interested in going to Ghana, Africa, June 2025-2026. We will be seeking to locate a plot of land to build an "Earthbag" style education center within 60 miles of Accra, Ghana.
