Several years of drought in a particular region of the country have led to dwindling water supplies. The state water authority in one of the affected states has evaluated the following pieces of evidence:
(1) A federal census study of population growth trends in the state.
(2) A state resource conservation commission study of per capita water usage levels.
(3) A state natural resources agency's study of aquifer levels in the state.
(4) Weather trends, as documented by the National Weather Service, over the last 30 years.
Based on this evidence, the water authority has reasoned that the state will run out of water in as little as 20 years, unless it takes drastic action now It has proposed building a pipeline to bring water from the sparsely populated area of the state to the cities.
