【题目】A new study warns that about thirty percent of the world’s people may not have enough water by the year 2025.

A private American organization called Population Action International did the new study. It says more than 335 million people lack enough water now. The people live in 28 countries. Most of the countries are in Africa or the Middle East.

P-A-I researcher Robert Engelman says by the year 2025, about 3,000 million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on the earth stays the same.

Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.

The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking water is not safe. Mr Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.

The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.

The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.

Red grouper(石斑鱼) are known for a few key characteristics — their color, which can 1from pink to bright orange; their tastiness, whether they’re grilled or fried; and their predation (掠夺行为) method, in which they 2 sea creatures and swallow them whole.

But their least-known characteristic might be the most valuable of all: They operate as underwater architects, 3 the seascape for numerous other forms of underwater life. That surprising discovery is 4 scientists and policymakers to readjust their approach to preserving the ocean’s natural order — and heightening tensions with those who fish for a living or as a hobby.

A team of scientists, led by Florida State University’s Felicia Coleman, recently found that the red grouper off Florida’s east and west coasts have created entire ocean 5by digging large holes in the sea’s sandy bottom. In the same way beavers 6dams, red grouper dig and maintain distinct holes whose rocky surfaces provide a place for coral, sponges and other marine life to gather.

This new understanding is changing the way federal and state authorities manage ocean habitats and is creating a completely new crack with fishermen. “The people who are in control want to 7 fishing as much as possible,” said Bob Jones, executive director of the Southeastern Fisheries Association. He added that the recent discoveries about red grouper amount to an “excuse they can use to restrict fishing, 8or recreational.”

But to many researchers, fishery officials and even some fishermen, the fact that fish act as environmental engineers provides a compelling reason to protect them from exploitation.

“If you 9 that fish, it puts into motion a whole chain of events,” said Don deMaria, who used to fish for red grouper near Key Largo, Fla., but no longer does. “There’s a whole lot of other animals that are 10. I’m not saying you can’t catch them. But you can’t do it to the extent we’ve been doing for the last 20 years.”
