關(guān)于保護(hù)水資源的英文文章篇一
Since 1900, the U.S. has pulled enough water from underground aquifers to fill two Lake Eries. And in just the first decade of the 21st century, we've extracted underground water sufficient to raise global sea level by more than 2 percent. We suck up 25 cubic kilometers of buried water per year.
That's the message from the U.S. Geological Survey's evaluation of how the U.S. is managing its aquifers. Or mismanaging. For example: water levels in the aquifer that underlies the nation's bread basket have dropped in some places by as much as 160 feet.
The rest of the world isn't doing any better. A conference of water scientists just issued the so-called Bonn Declaration, which declares that this lack of foresight will cause the majority of people alive in 2050 to face "severe" freshwater shortages.
Mismanagement of water resources is a hallmark of this new human-dominated era in the Earth's geologic history, known as the Anthropocene. Despite building, on average, one large dam every day for the last 130 years, we use more water than we store. And we're letting that freshwater escape to the seas. Which means we may find ourselves with water, water everywhere, but not much fit to drink.

Israel knows how to deal with drought. The small Middle Eastern country has experienced dry weather conditions and water shortages for many years. The American state of California is in the fourth year of a drought. So a Jewish group proposed a conference to show Californians what Israelis can offer in terms of technology, knowledge and support.
Barry Broad is head of the Sacramento Jewish Federation. He says the idea for the meeting wasa product of Sacramento's Sister City relationship with the Israeli city of Ashkelon.
"We thought given California's water situation -- we're in a very serious drought -- and Israel'sadvanced technology in this area...this would be the perfect Sister City event to plan. Bringingexperts from Israel to tell us what are the things we can learn from Israel's longer and moreextensive history dealing with life in a permanently arid climate."
In California, hundreds of thousands of people pay a flat rate for their water. In other words,they pay the same amount, whether they use a lot of water or very little.
Israel treats water differently. Eilon Adar is director of the Zuckerberg Institute for WaterResearch at Ben-Gurion University in the Negev desert. He says water is considered a nationalresource, like oil or natural gas. The Israel Water Authority sets the price of water. Mr. Adarsays that the more water someone uses, the more they must pay.
"In my country, when I buy a unit of water to my house, I pay for the water as a commodity; Ipay for the transmission, and I pay for the treatment of the water released later on from myhouse. And this, I think, is the key for success."
Israel has five desalination plants in operation. They remove salt from sea water so it can bedrunk and used to cook and clean clothes. More than half of the water for homes, farms andbusinesses comes from this desalination process.
A desalination plant will soon begin operating near the city of San Diego, California. CaliforniaGovernor Jerry Brown has called for a 25 percent reduction in the use of water. And inNovember, voters approved a plan for the government to raise money to help solve the state'swater problems.
Mr. Adar says the biggest barrier to solving California's long-term water problem may havemore to do with politics than technology. He says large cities in the southern part of the statedemand fresh water from the northern part.
Darryl Steinberg is the former president of the California Senate. He says cities throughout thestate have to stop fighting each other for water.
"Truth is, we don't have room for division here. It's one state. There's less water. There's morepeople, and we're going to have to be much more aggressive and come together in a muchmore effective way over time, if we're going to deal with this. And I'm confident we can."
Mr. Adar says farmers, property owners and water companies must work together to savewater. He says Israel will use its advanced technology, information and experience to help anycountry that asks.

Scientists may have found one answer to the problem of water shortages. It is a new material that collects water from the air. They got their idea from a small beetle that lives in the desert in Africa. The deserts of the Skeleton Coast in Namibia are very dry, but the Namib desert beetle is an expert at surviving in hot and dry conditions. Its shell is covered in small bumps that collect tiny water droplets from the air. The water is enough to keep the beetle alive. Scientists studied the shape and material of the beetle's bumps. They want to use what they found out about the beetle to make their own materials that can collect water from the air. This will help people who live in very dry areas.
The scientists believe this new technology could help in many areas of our life. They said it could be very useful for power plants and for the heating and air conditioning in airplanes, cars and trains. One of the scientists, Philseok Kim, said: "Thermal power plants, for example, rely on condensers to quickly convert steam to liquid water. Our design could help speed up that process and even allow for operation at a higher temperature, significantly improving the overall energy efficiency." Another scientist, Joanna Aizenberg, said she was looking forward to the future of getting ideas for new technologies from nature. She said: "Everybody is excited about bio-inspired materials research."
