Water scarcity is one of the most urgent crises of our time, affecting over 2 billion people worldwide. In many regions, particularly in Africa, families must walk an average of 6 km every day just to access water—often from unsafe sources contaminated with bacteria and pollutants. The lack of clean water not only threatens health and sanitation, leading to deadly diseases, but also disrupts education and economic stability, as children and women spend hours fetching water instead of attending school or earning a livelihood.
