Napoga is a 12-year-old girl in Ghana(加纳), Africa. It is hard for her family to get clean water. Every morning, she leaves home at half past five to get clean water for her family in a village far away. It takes her six hours to get enough clean water for daily (日常的) cooking and drinking. She has no time to go to school or to play with her friends. Millions of people in the world are like Napoga. They can’t get enough clean water to keep healthy.
Earth Day is April 22. But on all other days, we must also remember it. The water we use is the most important natural resource(自然资源) on the earth.
Water covers 70% of the earth’s surface(表面). But most of that is sea water. We can’t use it for very many things. Fresh water covers only 1% of the earth’s surface.
You probably feel lucky that your life isn’t as hard as Napoga’s. But that doesn’t mean you don’t have to worry about water. We all face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes, and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish, too. Now, 34% of all kinds of fish are dying out.
How do cars and factories make our water dirty First, they pollute the air. Then, when it rains, the rain water comes down and makes our drinking water dirty. Dirty rain, called acid rain (酸雨), is also bad for plants, animals and buildings.
Scientists say that in 30 years, more than half of the people in the world won’t have enough clean water. We have to learn how to save more water for ourselves and our children. Here is some advice for saving water:
Turn off the water while you brush your teeth. You can save as much as 450 liters (升) each month.
Leaky taps(水的龙头) waste a lot of water. Fix them right away!
You can easily cut your 1O-minute showers(沐浴) in half—and you’ll be just as clean.
When you wash dishes, don’t let the water run.
Only wash clothes when you have a lot to wash. If your washing machine isn’t full, you’re wasting water!

A:sea water is widely used than fresh water B:there is very little water for our living C:there is 71% of fresh water D:we don’t need to worry about water

Opportunities for water companies are flowing around the world because of looming shortages and decades of underinvestment. Saudi Arabia and Algeria, where water shortages have become acute, are placing billions of dollars of contracts out to bid to improve water supplies for their growing populations. The trend is expected to grow, as 40% of the world’s population will suffer water shortages by 2050, according to the United Nations Development Program. Global warming is expected to exacerbate the problem.
Saudi Arabia began privatizing water services after shortages sparked riots last November in Jeddah. Loay Ahmed Musallam, the deputy water minister, said the first contract to manage water supplies for Riyadh would be awarded this year. By 2010, private companies will provide water for half the population, he added. Saudi Arabia plans to invest $ 37 billion over five years to improve water pipelines. Leaks cost 1 million cubic meters of water a day--the output of seven desalination plants--the minister said. Even after putting contracts out to bid, governments still face politically sensitive decisions. In Saudi Arabia, for example, water tariffs are among the lowest in the world. Musallam said Saudis consumed twice as much water as Britons in spite of living in one of the driest parts of the globe. The government is introducing measures to encourage water conservation.
Even in the US, the shortfall between actual investment and the industry’s real needs is estimated to be $122 billion for waste water treatment and $100 billion for drinking water over the next 12 years, said Michael Dean of the Environmental Protection Agency. "People take for granted clean, safe, inexpensive water, but the old ways of paying for water in the US no longer meet our needs," Dean said.
Water services in the US are mainly owned by municipalities, which fiercely resist privatization. Gasson says decades of underinvestment are catching up with the water industry. "Either tariffs or subsidies will have to rise. We are at an inflection point. Investment now is unavoidable," he said.
David Lloyd Owen, a British consultant, estimated the investment shortfall for the global water industry at $1.2 trillion over the next 20 years. "The question is how to overcome political resistance to the involvement of the private sector," he said. "The water industry is one of the most conservative in the world. By and large, it is still run by bureaucrats and engineers," Owen said. "There is also a passionate and well-organized lobby against privatization."
He sees more room for the private sector as technology for desalination and recycling come to play an increasing role in the industry. Banks are also becoming more creative in matching the financing of capital outlays in the industry with the long lives of water treatment facilities.
