Coping with environmental crisis cannot but presuppose a change in the values adopted by modern man. Both ecocentric values associated with creating a caring relationship with nature, and the development of empathy, can become vehicles of transformation towards a society based on ecological principles. In connection with these issues, an Environmental Education program for preschoolers was designed and implemented in the classroom. The evaluation shows that preschool children can be interested in non-human beings, can feel the need to protect them, and ascribe them intrinsic value.
