The document discusses differences in water consumption and sources between high-income countries, low-income countries, and continents. There is a huge gap in daily water usage between HICs like the USA and Europe, which use 300-600 liters per person daily, and LICs in Sub-Saharan Africa which use around 25 liters. Water usage also differs significantly by sector, with Africa relying on agriculture for 85% of its water, Europe on industry for 54%, and the USA's usage being more balanced. Students are tasked with presenting this data visually and calculating their own household water usage over a weekend.
