Abstract
The enhancement of our knowledge about excessive burdens imposed on the natural environment, or rather about limitations of self-purification ability of ecosystems, has led from an awarness of the situation from fifty years ago to establishment of key directions, which must be included in all educational and learning programmes at all levels. The environmental education concept has grown into education for sustainable development, which has spread into all facets of human life and activities. Unfortunately, the practice does not meet the expectations which need to fulfilled to ensure a sustainable future, our responsibility towards the generations to come. This was confirmed through a researche study on drinking water as a key factor for achivement of the goals of education for sustainable development.
