Question

question 7 of 10
what is one of the major factors contributing to the global water crisis?

a. a global decrease in urban population densities
b. the contamination of river water by industrial pollution
c. the spread of desalinization plants around the world
d. the introduction of sanitation systems in impoverished countries

Explanation:

To determine the factor contributing to the global water crisis, we analyze each option:

• Option A: A decrease in urban population densities would likely reduce water demand, not cause a crisis. Eliminate A.
• Option B: Industrial pollution contaminating river water makes it unfit for use (drinking, agriculture, etc.), reducing available clean water. This contributes to the water crisis.
• Option C: Desalination plants increase water supply (by converting saltwater to freshwater), so their spread would help, not cause a crisis. Eliminate C.
• Option D: Sanitation systems improve water quality and hygiene, helping with water management, not causing a crisis. Eliminate D.

Answer:

B. The contamination of river water by industrial pollution
