In this article, the importance of using water wisely and conserving it for the future is discussed. The researchers looked at the concept of a "water footprint," which measures how much fresh water is used to make products at different stages of food production. There are three types of water footprints: blue (from rivers and groundwater), green (from rainwater stored in soil), and grey (polluted water). The blue water footprint comes from global water sources, while green water comes from rain. Grey water is polluted water linked to production. Understanding these footprints helps track water use and pollution. The goal is to use water efficiently to protect the environment and ensure there is enough water for the future.
