The vision for this World Environmental Education Congress is “Earth as our common home”. This is the “Oïkos”, or shared household, in which all life exists and in which all human and more-than-human activity rests. This “household” is the basis for all relationships and foundation for ideas about identity, solidarity, and socio-ecological relations with all forms of life. It is also the context that gives rise to ecology, ecosophy, and economy and relationships amongst them. This Congress will examine contributions that environmental education can make towards the development of relationships amongst these spheres of understanding at a critical period in Earth’s history, when we need to profoundly and urgently realign human endeavour within the capacities, limits, and systems of our home.
