One main area of focus and concern with this issue is the use of pesticides within these modern practices. One of the things that made farming so difficult before modern fertilizers is the loss of crops due to poor soil and falling victims to insects and animals that would feast on the crops. However today, with modern fertilizers, and soil enrichment chemicals, the yield produced by crops is astronomical compared to pre-modern practices.
The problem ensues when these chemicals are washed away by rainwater and make their way into rivers and streams which then make their way into watersheds and our water supply. It is this same water from our rivers and streams in which we use for drinking, cooking, and bathing. The United States Department of Agriculture estimated that 5 million people die each year from water-borne illnesses. 4 million of these being children die of diarrhea because their digestive systems are not equipped to digest such chemicals. In order to fix this problem, we must determine where these contaminations are coming from. Another problem is that a majority of these contaminations are coming from non-point sources, which are sources from which one particular source cannot be determined, but only narrowed down to a group of possible locations where these contaminates entered our water supply. Point sources, on the other hand, are sources that can be narrowed down and therefore corrected.
Because of their high yields and enormous profit margins, farmers are set on farming practices that continue to poison our water supply and deteriorate our ecosystems. At the same time, the negative effects these farming practices have on our environment are too severe and apparent to ignore. So what do we do? This paper will look at the causes and effects on modern farming practices and what is being done to limit and correct such effects.
