Whereas saving water in the household is something that people can directly observe and that assists in conserving local water supplies, this savings represents a small fraction of a person’s total water footprint, which includes the water required to produce the goods and services consumed daily. About 90% of personal water footprints is devoted to food in the form of crop and animal production. Altering food choices and reducing food wastage lead to the greatest reduction in water footprints. The most wasted food is meat (comprising one-third of the total in the USA), which requires the most water to produce when compared to other foods on a caloric or weight basis. In addition to its water demand, meat production is a major contributor to climate change, water pollution, global deforestation, and antibiotic-resistant bacteria. Water, food, and energy are interconnected in a so-called nexus, which means that attaining sustainability in any one sector is dependent on the others. Water is frequently considered the most critical sector because the other two are totally dependent on it.
