"Nature provides free lunch, only if we control our appetites." This is a powerful sentence. Nature cannot provide for a community that is taking faster than it can produce. Example, a mother with nine children cannot make them all lunch at once. Some will be served before others, and they will have to be patient. If all the children want seconds, the mother will be tired and may not be able to provide the second meal. Statistics from Webecoist state that, "Oxygen-starved dead zones that cannot sustain life now cover an area approximately the size of Oregon. Dead zones are caused by excess nitrogen from farm fertilizers, factory and vehicle emissions, sewage and other pollution runoff." Humans causing these large, and increasing, dead zones will cause an extreme depletion in sea life. These animals are dying due to human error.
