If water is recycled in the atmosphere, which best describes why water availability on Earth is decreasing?

• An increase in droughts is slowly reducing freshwater reservoirs.

• Due to an increase in Earth’s temperature, evaporation rates continue to increase reducing liquid water on the surface.

• Earth’s freshwater continues to become more polluted, reducing the supply of freshwater safe for humans to consume.
