As climate change and other crises strain water supplies, more attention is being paid to the water footprint, the amount of water used by an individual or household over a certain period of time. A water footprint includes the water that is directly used by taps, showers, toilets, and household appliances, as well as for outdoor uses. But the water used to make the food we eat, consumer products we buy, and energy we use is also part of a water footprint.
The rise and importance of the water footprint is discussed in this episode with Kai Olson-Sawyer, manager of the Water Footprint Project for GRACE Communications Foundation. Kai explains how people can use the Water Footprint Calculator to learn about their personal consumption and shares ways that individuals can reduce their impact.
