We would like underline the importance of studying values related to pro-environmental attitudes generated both in the school and in the community. The best way to explore it is discovering the roots or causes of the problem, by means of the study of the attitudes, as well as the relations that the mankind established and currently establishes with the environment. We try to place the environmental ethic within the framework of education in values. In sum, the principle which lies behind this research is to promote in the individual values and attitudes favourable to the conservation and improvement of the environment, as a way of contributing to the solution of environmental problems, to improve decision-making and to orientate actions.
