Abstract:Building social alternatives is necessary to resist the destructive impacts of the capitalist organization on well-being, social organization, and the planet. This paper offers an analysis of the ways in which peoples are mobilizing to build organizations and to define social movements to move beyond current crises. The lines for constructing an ecologically sound and social-solidarity society require mechanisms for mutual cooperation based on alternative systems of decision making, as well as for doing work and assuring well-being to every member of the community. These depend on forging a process of solidarity among the members of a society as well as building alliances among communities; to assure the satisfaction of basic needs while also attending the most pressing requirements for physical, social and environmental infrastructure and to assure the conservation and rehabilitation of their ecosystems.
