Environmental issues are alive and current in all european countries. One of the attributes is the problem of declining water resources and the associated difficulties. The project will be implemented by students from 6 countries in Bulgaria, Greece, Croatia, Lithuania, Slovakia and Portugal. Participation in this program will encourage pupils to recognize global environmental problems. Together with students from partner countries, they will get to know nature theoretically and practically. This will lead them to its practical protection. They will be able to compare activities in different countries and will learn by working together. Pupils improve their english conversation and get to know the language of the partner countries.
