Every day at least 10000 persons in the world die of starvation, according to the World Health Organization.
One-third to one-haft of the earth's population is under-nourished (营养不良的) even though more than the
necessary food for everyone on earth is available (可获得的).
    Many nutrition experts (营养学家专家) say that one of the reasons people starve is that they are willing to
eat only the kind of foods they are used to. For example, enough rice to feed 1000 Chinese would be left to
spoil among Eskimos, who don't eat rice. A store house full of bacon that would be food in many places
around the world would mean nothing to millions of East Indians, who won't eat pork (猪肉) for religious
reasons. Another group of East Indians, called Hindus, won't eat beef because their religion forbids it. Instead
of being butchered, cows are allowed to roam (闲逛) freely in the streets in Indian cities.
    Thousands of scientists in all parts of the world are working to change soybeans (黄豆) and fish meal into
food that people of different nationalities will eat. Both soybeans and fish meal are high in protein (蛋白质) and
are available in large quantities. These scientists feel that human eating habits are often at the bottom of the
world-wide food problem.
