Answer to Question 1

c

Answer to Question 2

Water stress results when the demand for water in an area exceeds availability. The average supply of fresh water per person may decline by one third in the next 20 years. Water stress is accelerated by water pollution. Each day, people dump 2 million tons of waste into the world's freshwater rivers. This leads to aquatic ecosystem destruction, which further degrades the environment and reduces wild food fish populations.
