Imagine trying to feed nine billion people with enough meat.In short，its simply impossible. Australian journalist and science writer，Julian Cribb，explains the challenges the world faces in feeding nine billion people by the year 2050.Cribb says there is a major problem in the current food system in the developed world，,at least.As more and more people move towards city centers，the less and less they know about where their food comes from.Most think food simply grow on supermarket shelves，and they dont consider the environmental effects of food production. Food has many hidden cost: huge volumes of water，energy use and land degradation(退化).Consumers add their own costs by simply throwing away a lot of food.The figures for food waste in West are staggering .,To solve this problem of public ignorance(无知) about food.Cribb suggests that food should be taught as a subject at primary school.This would help to create a future generation that could better deal with the worlds coming food challenges.This powerful measure can help to raise a generation of educated consumers，more productive farmers，and so on. Cribb offers other solutions and suggestions as well.One is to increase the funding for agriculture science，which has been falling by the wayside in recent years.He suggested organic(有机的) farming should be understood on a scientific basis，,changing peoples thinking to one of a new form of “environmental agriculture” to get the very best out of organic farming systems.He says we should stop wasting food and learn how to grow food more cheaply.We should use less water，as water is one of the main inputs into food production.Cribb also suggests eating more fruit and vegetables.,( ) 1.In the second paragraph，one problem of the food system in developed countries is _. A.increasing ignorance about the ways of food production B.an increasing number of people moving to city centers C.food production doing harm to the environment D.the cost of food production is increasing ( ) 2.What is the meaning of the underlined word in the third paragraph?

B.To help students understand how to grow food. C.To develop agricultural science. D.To train more productive farmers. ( ) 4.Which of the following may the writer disagree with?,A,B,A.The public should save food and save water. B.Organic agriculture costs a lot of resources. C.More money should be used for agricultural science. D.People should eat less meat but more fruit and vegetables. ( ) 5.The text is mainly about _.
