Which statement about water use is accurate?

Which statement about water use is accurate?

• A. Excessive water use can contribute to global water stress.
• B. It always increases rainfall in all climates.
• C. It reduces energy consumption.
• D. It has no impact on ecosystems.

Answer: (A)

Understanding how water withdrawals relate to global water stress. When withdrawals of fresh water exceed what nature can renew through rainfall and recharge, rivers, lakes, and aquifers fall, limiting water for people, farms, industry, and ecosystems. That tension—high demand relative to renewable supply—is what global water stress describes, so the statement that excessive water use can contribute to this stress is the best choice. Rainfall isn’t guaranteed to rise just because more water is used or drawn from sources; rainfall depends on climate and atmospheric processes, not on human withdrawals. Water use also doesn’t inherently reduce energy consumption; moving, treating, and distributing water typically requires energy, so high water use can increase energy demand. And water use does impact ecosystems—altered flows, habitat loss, and water quality changes can harm aquatic life and surrounding environments.
