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 Earth stays the same．

   Mr．Engelman says the population in countries that lack water is growing faster than ini 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 waters 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．

The olive is one of the oldest planted crops known to man and is still widely grown in the Mediterranean.An olive tree can have a life of 500 years and is strong enough to continue to grow if ever chopped to the ground.It takes up four years before the olive tree is ripe enough to bear fruit.

Olive trees originated in the Mediterranean region where there is the perfect climate for the olive tree planting.It is characterized by abundant sunshine year-round and hot,dry summers with an average temperature of 80°F.In winter,it rarely drops below 50°F.Olive trees were first planted by humans around 4000 BC in an area known as the Fertile Crescent.Before the areas became desert,countries such as modern-day Turkey and Iraq had a lush environment with soil that plants grow well.Archaeological findings suggest that farming began in the Fertile Crescent before 7000BC.Instead of living as hunter-gatherers,these early humans settled down and harvested native plants.They selected olive trees that produced larger and oilier olives than the wild trees.

Olives and olive oil became valuable trade items between societies and civilizations.People who moved from one place to another and traders from the Fertile Crescent introduced olive oil to Syria and Crete,which spread to Egypt,Greece,and Rome.It continued to migrate westward until olive trees were first introduced to Califomia between 1769 and 1785.

The olive tree and olive oil have important symbolism in each religion.In Christianity,a dove(鸽子)brought an olive branch to Noah as a symbol of peace and new life after God flooded the Earth.The Prophet Muhammad suggested the use of olive oil for medicinal(药用的) purposes and massage(按摩).

Olive oil has medicinal benefits.Olive oil has been used for health benefits.Regular eating olive oil can reduce the risk of cancers.It was used during the Spanish Civil War from 1808 to 1813 to treat cases of fever.In 1960,oleuropein(橄榄多酚)was removed from olive leaves,which helps with food poisoning.
