Elise Kim ENGL 101 Fritz 11/18/10 Improvements in the Management of Animal Waste Over the past century, the animal industry has been growing tremendously because of the great demands for meat and dairy products. The push for mass production in the livestock industries evolved many farms into producing much more affordable products. These farms known as the concentrated animal feeding operation, or CAFO, confine animals (Weeks 25) . The increase in production has caused an increase in animal waste and as a result, the manure has greatly affected the environment negatively. The quality of water has decreased because of the runoff of animal excrement, which caused the living organisms in rivers and streams to die because of the lack of oxygen that resulted from the increase in algae. In addition to the bad quality of water, the soil and air have been affected. The pollution of the soil and air brought up many sanitary issues because of the crops with unwanted hormones, offensive smell, and the spread of pathogenic microorganisms. Thus, these negative aspects of the problems made many think that it is difficult to control the animal waste because of what it has already damaged. Therefore, it is important to understand why many believe in these harmful environmental affects and to make sure that they become unbiased by making them understand that there can be simple changes in the techniques of managing manure. Admittingly, to many people’s understanding, animal waste is one of today’s major water pollutants. According to Environmental Protection Agency (EPA), 40% of US waters are polluted and are not “swimmable” for fish (Cooper 653); the main reason is because of

runoff. After storing the manure in the lagoons, farmers make fertilizer out of it and spray it on their crop fields. The fertilizer is full of phosphorus and nitrogen, and when farmers use too much of it, the nutrients seep through the soil and end up in bodies of water (Cooper 966). The addition of nutrients into streams and rivers, “ [lowers] dissolved oxygen in [water] to levels that cannot support most animal life” (Osterberg and Willinga 1704). Livestock waste can “[empty] into the Gulf of Mexico, [causing] a lifeless “dead zone”” (Cooper 955). Therefore, many believe it is difficult to control runoff, and consequently is tough to create a strong policy. In addition to water pollution, there is an understanding of how animal waste affects
