Have you ever considered the water footprint of the products you use or the foods you eat? The volume of freshwater used in the lifecycle or production of a food or product is called virtual-water content. This takes into account the volumes of water consumed and polluted over its full production chain.
For example, due to cotton being a water-intensive crop, one pair of jeans has a virtual-water content of 11,000 litres!
March 22nd is International World Water Day; and as we continue to challenge ourselves, and the community, to find more ways to build and live with sustainability in mind, virtual water will become a larger part of the conversation.
