Why Do Factory Farms Cause Avian Flu?

First off, factory farms, congested cities, and globalized poultry trade are the cause of the avian flu because livestock waste damages the climate at a high rate. Adding on more information, the waste from Concentrated Animal Feeding Operations (CAFO) are a huge source of very toxic pollution without any good way of disposing it. Feedlots are also breeding grounds for new and deadly bacteria. In this case, new bacteria is forming without us being aware of it. The animals have adapted and are used to eating grass. However in a CAFO, they are forced to eat corn for their health. Factory farms should treat chickens

“By concentrating large numbers of animals together, factory farms are terrific incubators for disease. The stress of factory farm conditions weakens animals' immune systems; ammonia from accumulated waste burns lungs and makes them more susceptible to infection; the lack of sunlight and fresh air--as well as the genetic uniformity of industrial farm animal populations--facilitates the spread of pathogens." (Sayre) To summarize this section, it states that factory farms are creating diseases and because of this, the stress of the factory farms condition weakens the animal's immune systems. The animals that are caged up in these factory farms lack sunlight and fresh air. This is also the cause of pathogens spreading. Animals in these factory farms are crowded into small places with barely any room to even turn around. They are kept in there and fed hormones to grow their bodies until they become an unnatural size. This happens so that the animals can produce more meat. This is dangerous for them because the farmers are taking away the animals freedom. Factory farms conditions weaken the animals immune systems and this is putting the animals at risk for an infection. With the lack of sunlight and fresh air, the animals aren’t getting enough nutrition into them to fit off disease. The final piece of text evidence supports that caging animals is not good for them. Hui states, “In the wake of such criticisms, many companies have turned to experts like Dr. Grandin to help them understand animal welfare better: what motivates animals; what behaviours come naturally to them; and what causes them fear, stress or pain." (Hui) As explained in this quote, there are many criticisms to people caging animals and treating them inhumane. However, several companies left are still willing to help others understand animal welfare. In addition, he analyzes what behaviours come naturally to them along with what causes
