This article charts the history of environmental education over four decades--from the 1960s to 2006--as a rocky road of determined chocolate with the possibilities of rocks (nuts) and easy passage (marshmallow). There were distractions such as suggestions of changing names and new directions (add fruit?) along the way but the road has continued to be well travelled. The article concludes that there is much in common with where we have come from (the 1975 Belgrade Charter) and where we stand now (in year 2 of the United Nations Decade of Education for Sustainable Development). Where next?
