Food is taken for granted by many people in places like the Western world, especially in countries like the United States. There is no fear that your next meal will be an empty plate, nor is there any reason to fear that your food reserves will disappear. The reason there is no need to ration supplies is that the food industry mass produces food to feed its ever-growing population on factory farms. However, the public is generally kept in the dark about what happens inside these farms, which calls into question the integrity of food production. Although these farms are accepted for the convenience they offer to the consumer, there are many negative consequences associated with these slaughterhouses. Mass production of food from intensive farming does not justify the negative effects and threat to the environment, animal health and safety, nor the violation of workers' rights. First, the threat to the environment from factory farming. The mismanagement of the waste produced, which contaminates the air, soil and water in their communities, is often unacknowledged. This is because the industry does not want to admit the harmful environmental impacts created by concentrated animal feeding operations (CAFOs). According to Daniel Imhoff, “100 acres of land for an animal feed factory generates the same amount of sewage as a city of 100,000.” (CAFO xii) This idea was exemplified in a study in the United States, where waste was measured; it has been found that 500 million tons of waste are produced per year, which is three times the amount of the US population (CAFO xii). Another study found that for every medium of paper and sentient being, more than a ton of "dry matter" animal waste was produced. Since our society has become so desensitized to the industrialization of mass slaughter in the name of "sales economies", clearly our "educated society" has had an extreme ethical collapse. According to Matthew Scully, literary editor of the National Review: "The moral teachings of every major faith recognize that cruelty to animals is shameful and wrong, but somehow these widely held principles are rarely translated into serious political debates about the treatment of animals. ” (CAFO 11) If you accept that the principle of animal cruelty is wrong, immoral, and evil, then there is no justification for the harmful treatment of animals in places like concentrated animal feeding operations that marginalize and industrialize nature to adapt to an industry, rather than having an industry built to meet needs and protect nature.
