This article attempts to visualise the way in which children and young people think about a specific topic, namely the environment. The aim is to make the thinking of children and young people available and to interpret the meaning of their thoughts about our environment. The theoretical roots of the study are to be found within the phenomenology of the lifeworld. The study is based on empirical material consisting of drawings produced by 109 children and young people, combined with subsequent oral comments. During the drawing analysis different structures and patterns gradually crystallised, and eventually four different themes emerged, consisting of thoughts which focus on the following: the good world, the bad world, the dialectics between the good and the bad world, and symbols and actions protecting the environment. It can be stated that the results which emerged, in the form of the thoughts of the children and young people on the environment, reflect a thinking characterisedby many nuances, such as clean and unspoilt nature in different manifestations, the need for human beings to use nature for recreation and well-being, environmental destruction in different forms, and direct or indirect ways of taking care of the prevailing environmental situation.
