We need it to drink, cook, clean, and even for farming. Without water, we couldn’t survive. Do you think we use too much water? Student A: Definitely. I think we waste a lot of water, especially in cities. That’s why we need to save it. Do you know why saving water is so important? Student B: Yes, because clean water is limited, and if we waste it, there might not be enough for everyone in the future. Plus, saving water helps protect the environment. Student A: That’s true.
