Montessori school communities (parents, students, educators, supporters) are centrally positioned to lead a global revolution in school-based outdoor education – supporting the next generation of planetary lifeguards who understand the universe and are educated to lead in caring for the Earth. NLI has carefully curated resources to inspire nature-based action to increase biodiversity, to make it playfully accessible – hands-on yet protected – along with other play and learning settings – fixed and loose, natural and manufactured – necessary to meet best practice standards across the Montessori planes of development.
