The greatest threat to the survival of ECOWAS is the inability to implement agreed policies. ECOWAS, or the Economic Community of West African States, is a regional organization that aims to promote economic integration and cooperation among its member states. However, the success of this organization relies heavily on its ability to implement policies and agreements that benefit its member states. If policies are not implemented, then the goals of the organization cannot be achieved, and member states may become frustrated and disillusioned with the organization. This could lead to a lack of trust and cooperation among member states and ultimately threaten the survival of ECOWAS. The other options listed, such as different languages spoken and different monetary systems in use, may present challenges to achieving economic integration, but they are not the greatest threat to the survival of ECOWAS.
