Humanity uses a little less than half the water available worldwide.
Yet occurrences of shortages and droughts are causing famine in some
areas, but industrial and agricultural by-products are polluting water supplies. 【S1】________
Since the world’s population is expecting to double in the next 50 years,【S2】________
many experts think we are on the edge of a widespread water crisis.
But that doesn’t have to be the outcome. Water shortages do not
have to trouble the world—if we started valuing water more than we【S3】________
have in the past. Just like we began to appreciate petroleum more after【S4】________
the 1970s oil crisis, today we must start looking at water from a fresh
economical perspective. We can no longer afford to consider water a 【S5】_______
virtual free resource of which we can use as much as we like. 【S6】________
Instead, for all uses except the domestic demand of the poor,
governments should price water to reflect their actual value. This means【S7】________
charging a fee for the water itself as well as for the demand costs.【S8】________
Governments should also protect this resource by providing
water with more economically and environmentally sound ways. 【S9】________
Often the cheapest way to provide irrigation water in the dry tropics
is through small-scaled projects, such as gathering rainfall in depressions【S10】________
and pumping it to nearby cropland.
【S3】
