The Montessori approach has an ecological basis and views all living and non-living things on this planet as strictly interrelated and the North American Montessori Centre Curriculum states that environmental awareness is closely tied to peace studies, especially as it relates to our responsibility for ecological imbalances in the world.
The Montessori Peace Flower has four petals:
Self Awareness: education and spirit
Community Awareness: governance and education
Cultural Awareness: culture and economics
Environmental Awareness: health and environment
