Factory farming is a type of farming that involves raising a huge number of livestock（牲畜）in comparatively tinier enclosed spaces, with a view to supplying them to the livestock market. It took root in the later part of the 19th century. On the arrival of the Industrial Revolution, the inventions of antibiotics and pesticides were increasing in number, which made it possible to practice factory farming. And gradually, with better farming methods, livestock were able to be raised indoors leading to mass production in a shorter while. Nowadays, according to reliable sources, more than 50% of the livestock are produced using this concept.

Factory farming is one of the most important food production methods around the world today because it has a lot of advantages. For example, there are huge numbers of mouths to feed, and mass production leads to the purchase of poultry and the related items. Since the items aren’t priced too high for consumers to afford, people appreciate buying them in a large number. And as more and more livestock are artificially raised, more and more chicken, beef and eggs are out for sale. The purchase rate is higher and despite being reasonably priced, the produce fetches a profit for the farms. In addition, since the business is enormous and needs as many hands as possible to increase the food produce, an equal number of staff are required for work, which results in a growth in the related jobs.

However, there are also disadvantages of factory farming. For instance, the animals are artificially bred, and since the procedure is not natural, the end products could be of poor quality. Antibiotics are injected into cows and hens, making them more unlikely to suffer from dirt and disease. As a result, the eggs and meat will not be as good as usual. The products thus obtained are of such low quality, which ultimately affects our health as well. Actually, since the entire production is artificial, the meat is overloaded with hormones（激素）and drugs, and the bacteria develop resistance to the antibiotics, which is why many diseases remain untreated. Worse still, the animals’ waste can pollute the water and air, causing extensive damage to the environment. It may also lead to harmful emissions and contribute to the already increasing global warming.

Because of the above advantages and disadvantages of factory farming, the concept has been a subject of massive debate all over the world, wherever this practice has been employed. Supporters of this concept argue that it does provide enough food for the increasing population and is more affordable. However, unfavorable opinions suggest that there are better ways of producing food, rather than subjecting animals to this suffering. The debate has been going on for quite a while, with no one being able to gain the upper hand.
