LESSON 1 · Water: Earth's Scarcest Treasure

Water Equity Matters

The freshwater crisis is fundamentally a justice issue. Where safe water is scarce, the burden falls hardest on women and girls in developing nations, who spend an estimated 200 million hours every day collecting it.

Climate change widens the gap. Wealthy nations can build desalination plants and import food, while poorer nations face declining rainfall, shrinking glaciers, and contaminated groundwater with few resources to adapt. As supplies tighten, the more than 260 river basins that cross national borders are turning into flashpoints, with disputes escalating from diplomatic tension toward open conflict.
