Question

Why is water conservation important?
a.
It is important in desert areas because water is scarce, but not in areas with high levels of precipitation.
b.
Water conservation is important because people are currently consuming freshwater resources faster than they can be replenished.
c.
Water conservation is important because only 10% of Earth’s water sources are usable.
d.
All of the above are true.

Answer 1

Correct answer: b.

Explanation:
- (b) is true: many freshwater supplies (especially groundwater) are being used faster than they recharge, so conservation is needed.
- (a) is false: water conservation is important everywhere, not only in deserts — even rainy regions can face seasonal shortages, pollution, infrastructure limits, and increasing demand.
- (c) is false: far less than 10% of Earth's water is usable. About 97.5% is saltwater; only ~2.5% is freshwater, and an even smaller fraction (around 0.3–1% of total water) is readily accessible for human use.
