抗生素,温室效应 z-bo 2020-10-21 342

　　The abuse of antibiotics has become a global problem. The World Health Organization has published an article calling on people to become resistant to bacteria. By 2050, this bacteria will kill 10 million people every year and cause 100 trillion US dollars in economic losses.

　　If global coordination is not carried out immediately, the world will enter the post-antibiotic era, by which time normal infections will be fatal again. For example, the first "superbug" infection occurred in the United States, and all antibiotics did not help.

　　According to the latest research, the abuse of antibiotics is not only harmful to the human body, but also has serious consequences for the air environment and agriculture.

　　The research team led by Dr. Tobin Hammer of the University of Colorado found that cattle taking antibiotics may release more methane gas, which is not good for the climate.

　　They chose 10 cows, 5 of which took the antibiotic tetracycline, which is commonly used in agriculture, and 5 did not. It was found that the amount of methane in the feces of cows using antibiotics was twice that of cows not using antibiotics. The researchers said that antibiotics changed the microbial environment in the stomach and feces and increased the number of methane-producing microorganisms in the cattle intestine.
