Hog Farming
In a little over a decade the U.S. has seen a massive shift in the agricultural economy from smaller, family owned farms to larger corporate farms. This has lead to many families that once relied on farming being forced to sell their farms to larger corporate farms and sometimes leaves families impoverished. As these corporations have grown more powerful economically they have also grown more powerful politically. Some corporate farmers have used this power to get laws and regulations passed that allow them to operate in ways that are extremely harmful to the environment and the surrounding comunities. These corporations have been receiving most of the government subsidies for farmers and thus president Bush has proposed an agricultural reform bill that would cut government subsidies to any farm that makes more than $200,000 of income a year. Although Bush’s main reason for proposing this bill is because of economic concerns it could possibly have a positive impact for the environment as well. This is because smaller, family owned farms are traditionally much less harmful to the environment than large corporate farms and therefore by promoting smaller family farms we also promote healthier and safer environmental practices.
This trend of corporatization of farming is most visible among hog farms in North Carolina, specifically eastern North Carolina where sandy soils and high water tables make contamination of groundwater an even bigger threat. A hog produces 2 to 5 times as much waste as an average human and these hogs are fed in confined animal feeding operations (CAFOs). Until recently little was known about the environmental effects of these confined animal feeding operations because the industry has grown so quickly, but without much thought or imagination, the simplest mind can comprehend how a large concentration of hogs in a small area will impact the world around them. The 9.5 million tons of hog waste produced annually is...
