2. What factors are responsible for the decline in freshwater worldwide?

The correct answer is: A. Overuse, pollution, and climate change.<br /><br />Explanation: The decline in freshwater worldwide is primarily due to overuse, pollution, and climate change. Overuse occurs when water is extracted from sources faster than they can be replenished, leading to depletion. Pollution from industrial, agricultural, and domestic sources contaminates freshwater supplies, making them unsuitable for consumption and other uses. Climate change affects precipitation patterns, increases evaporation rates, and leads to more frequent and severe droughts, all of which contribute to the decline in freshwater availability.
