Most of us have three meals a day .We take food for granted(想当然)。And we don’t think about it.       experts argue a food crisis(危机)is coming.This crisis is going to make us     the way we think about food.

Food is in great need    a growing of world population.By 1960,the population was three billion.It doubled to six billion by 1999.By 2050,this planet will need to     at least nine billion people.As a result,the food prices get higher and higher.

So,what can a     ,crowed world do?One suggestion is to eat less meat.Meat uses more natural resources(资源)than grains(谷物) .It requires more       to produce one pound of meat than to produce one pound of grain. It also requires between 5 and 10 times more water than vegetables. So ,eating less meat will     more land for farming,and it will save water.

To eats less meat,people will need to change their eating habits. That will not be easy. Americans, for example,have     loved meat. In general, They eat twice as much meat as people in other countries.At the same time,in developing countries like China and Brazil,sales of meat have doubled in the last 20 years.     will double again by 2050.Growing need of meat wil continue to put pressure on natural resources.

World  population is increasing,resources are becoming fewer,and food prices are rising.Therefore, we need to rethink what  we eat every day. For meat lovers, we don’t  need to give up meat     .But we need to eat more grains and less meat.
