问题    America is the country of fast food. An ordinary young person in the USA eats on average 6 hamburgers a week and about 300 a year. Americans are consuming 23 % of the world’s meat production. According to the US Ministry of Agriculture, the amount of meat that one person in the USA consumes in a year is 120 kilograms, or about 330 grams a day. The daily recommended amount of protein is 60 grams, but most Americans eat five times more than this.

   They have developed a special method of livestock farming in order to meet the need for the huge amount of meat. The cows are fed without any exercise to become fat at the lowest cost. This causes them to hold much more fat than cows that are left to graze on grass. The way in which cows are raised on a large scale is called factory farming.
   In the Central Valley, some farms raise up to 2. 5 million cows on about ten thousand acres of land. One-year-old cows that enter the breeding farms weigh approximately 700 pounds. These cows are raised to weigh 1,200 pounds in about 4 months and then are slaughtered. They gain the same amount of weight in 16 months that a normal cow would gain in 7 or 8 years. In order to make this speedy increase, they must not exercise, but can eat and drink as much as they want.
   The pink veal that is considered luxurious is not produced all that graciously. Newborn calves are separated from their mothers and locked up in small compartments to prevent their muscles from developing so that the meat will be tender enough even for a baby to eat. This method of breeding leads to serious weakening of the immune system of the calves. Therefore, a lot of antibiotics and growth hormones are injected into them.
   The human desire for tastier meat has changed even what the cows feed on. Now cows eat corn, beans, and flour. Moreover, since the cows need to become fattened in a short period of time, the amount the cows eat in a day at a large factory farm is incredible. Seven kilograms of grain is needed for every kilogram of meat produced.
   In this world today, 1. 1 billion people are suffering from diseases caused by famine and malnutrition. Ironically, another 1. 1 billion are simultaneously suffering from diseases caused by over-nutrition and obesity. If Americans decreased their meat consumption by 10% , 12 million tons of grain would be leftover every year, and this could feed 60 million people who are starving.
