Nature preservation directly depends on the environmental education of the society. Compared to the other member states of the European Union the ecological culture in Lithuania is still low. Morals is of utmost importance in achieving ecological culture. Environmental events is one of the forms for developing a modern personality, who understands and is able to solve the issues of nature preservation. Environmental evens (presentations, actions, excursions, etc.) should be intended not only to promote interest in environment but also participation in preserving it. This paper reviews the results of a survey carried out among the schoolchildren (5 – 8) of Vilnius Fabijoniškės and Vilnius Žemyna secondary schools. The aim of the survey was to analyse the importance of environmental events as a means of ecological and moral education. Concluding the results of the survey it may be said that the indifference of schoolchildren to nature is related to lack of environmental education in the family. Accordind to the data of the survey even 76.3 percent of respondents consider enviromental events effective. The school system developing a modern personality, who is able to live in the rapidly changing world and solve the issues that arise in it, including enviromental ones, should develop and implement environmental programs and take part more in the different programs supported by international funds.
