Virtual water refers to the water that is used in the production of goods and services. It is essentially the hidden water footprint behind the products we consume. This concept helps us understand the amount of water embedded in various products and services.
For example, the virtual water of a cotton t-shirt includes the water used to grow the cotton, dye the fabric, and manufacture the shirt. By considering virtual water, we can become more aware of the water resources required to produce the items we use daily. This awareness can lead to more sustainable consumption habits and water conservation efforts.
