[01:59.88]Lesson 14
[02:09.15]2 Reading comprehension
[02:13.69]FEED THE WORLD(1)
[02:17.85]Agriculture first started about 10,000 years ago,
[02:23.49]when people began to grow crops in the river valleys of the Nile in Egypt,
[02:30.15]in the Middle East and in India.
[02:34.83]Today farming employs more people than any other type of work.
[02:41.38]It is thought that one billion people,
[02:45.64]that is half the world's workers,earn their living by farming.
[02:52.30]The problem is how to feed a growing world population of over 6 billion.
[02:59.96]For one thing,two thirds of the earth's surface is water,
[03:06.49]although this does provide a lot of food in the form of fish.
[03:12.97]Only about 11% of the earth's land surface is suitable for growing crops.
[03:21.33]And this area is becoming smaller day by day.
[03:27.57]In China there is only 7% of the land used for growing crops,
[03:35.33]which feed 22% of the world population.
[03:41.20]That is why the Chinese people are making great efforts to protect their farmland
[03:48.36]and increase agricultural prlduction.
[03:52.91]Farmland is being lost for several reasons.First,it is being built on.
[04:01.45]Second,when wind and rain have removed a lot of the soil,
[04:08.11]no more crops can be grown on this land.
[04:12.97]Third,a lot of irrigated land has become too salty to grow plants.
[04:20.34]Also,it is well known that pests continue to eat crops,causing damage.
[04:28.49]The FAO(Food and Agriculture Organization of the United Nations)
[04:37.73]has worked out that up to 30% of food is lost in storage.
[04:44.29]Food stores are frequently ruined by rain or damp,or eaten by mice.
[04:52.15]In a word,hunger is a big problem in the world today.
[04:58.11]No one is sure how many people are hungry,
[05:02.86]but it is thought that 500 million people in the world do not have enough to eat,
[05:10.62]that is about one in ten.
[05:14.78]Every year about 40 million people starve to death.
[05:21.12]Various things can be done to increase the food supply in the world.
[05:27.08]The area of farmland can be increased by irrigation.
[05:32.64]Take the Aswan Dam in Egypt for example,
[05:37.40]where desert land can now be used for growing crops.
[05:42.44]The same has happened in the west of the USA,
[05:47.19]particularly for the growing of fruit.
[05:51.27]Farmers can increase their corn crops three times simply by watering their fields.
[05:57.93]In Europe,Holland continues to increase its area of farmland
[06:04.77]by pumping water from low-lying areas.
[06:09.45]Scientists continue to develop new types of plants which prlduce heavier crops.
