By 2025, it is anticipated that 1.8 billion people would live in countries or regions where water is scarce, putting two-thirds of the world’s population at risk. Agriculture uses over 70% of the world’s fresh water, with 1 kg of beef requiring 22,000 liters (or possibly more), 1 kg of pork requiring 3,500 liters, and 1 kg of chicken requiring 2,300 liters.
