Researchers are linking the growing dependence on the drugsto rising demand for meat, milk and eggs. The researchers warn the drugs could quicken the development of antibiotics­resistant (耐抗生素的)infections. Such infections are already a major public health concern in the United States.Experts say when people stop living in poverty, the first thing they want to do is eat better,rather than earn more money. For most people, that means their diet should contain more meat. Increasing prosperity in Asia has meant people there are eating nearly four times as much meat, milk and dairy products as they did 50 years ago.To meet that demand, farms have put many animals into smaller spaces. As the animals are crowded together, often the easiest way to deal with some of the problems of crowding is to give them antibiotics. It’s clear that antibiotics help animals stay healthy in a crowded environment and grow faster. But bacteria can develop resistance to the drugs gradually, and the antibiotics-resistant bacteria can spread to people.Doctors find that antibiotics that once worked against the infections no longer do. The bacteria have learned ways to fight the medicine. Doctors say the heavy use of antibiotics in animals is one of several reasons for the growth of antibiotic resistance worldwide. In the United States, at least two million people get drug-resistant infections each year. At least 23,000 die from an infection.Ramanan Laxminarayan heads the Center for Disease Dynamics, Economics and Policy. He says the problem is expected to get worse.

He and other researchers wrote a report on the study, which was published in the Proceedings of the National Academy of Sciences. They used data from the United Nations that tell how and where livestock(牲畜) are raised today. They then predicted how such production would change by 2030.Europe has banned the use of antibiotics to increase animal growth.
