To establish a global profile that not only possesses theoretical knowledge of sustainability but also actively engages in implementing change, four schools from Poland, Italy, Turkey, and Romania, each with unique backgrounds and experiences, formed a partnership under the project titled ‘H2Our Life’. This initiative focuses on students aged 6–14 years, aiming to foster environmental consciousness and action. Water scarcity, a growing global concern, is influenced by factors such as increasing population-driven water demand, global warming, climate change, and natural disasters like floods and droughts. Additional contributors include industrialization, the unavailability of freshwater resources, and financial constraints, all of which vary significantly depending on national policies and local conditions.
