And they aren’’t necessarily in the future, either. Here’’s what we’’ve read in the past week or so.

We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want.
Instead, for all uses except the domestic demand of the poor, governments should price water to refl
A. build big lakes to store water
B. construct big pumping stations
C. build small and cheap irrigation systems
D. channel water from nearby rivers to cropland
