In the current study, we focus on how the early childhood education for sustainability (ECEfS) program develops the perceptions of preschool children about the human-environment relationship. The sample of the study consisted of preschoolers aged 60-66 months in Ankara, Turkey. The data were collected through the drawings of children on the topic of 'human-environment' and interviews on drawings obtained before and after the program. The findings revealed that children perceive their environment as a peaceful and gentle place. Furthermore, children conceptualized the environment through unusual and fantastic elements and they described the environment through secondary sources. There was a shift in descriptions in the post- and follow-up drawings including proposing recycling as a way of reconstructing the human-environment relationship, with making connections between global issues. In parallel to post findings, follow-up drawings gained after 10-month of the implementation highlights children's own solutions for a sustainable future.
