Modern Agriculture

Agricultural technology in the United States is responsible for producing abundant levels of food,but is also the source of many inconveniences.One example of this is the runoff of agricultural chemicals,which causes high levels of nitrogen and phosphorus in many lakes and rivers.when the excess nutrients applied to the land in the form of fertilizers find their way into the water,blooms,or overabundant growth of algae and other aquatic plants ,result.The algal blooms at the water surface affect the photosynthesis process of the submerged plants by blocking their sunlight,causing them to die.This problem is compounded when the oxygen levels drop,and organisms which flourish in oxygen starved environments release hydrogen sulfide and methane,which are toxic to fish and other aquatic life.The loss of species of fish and other animals,degrades and simplifies the ecosystem,making it more vulnerable to further destruction.

technological advances in animal husbandry have produced colossal outputs of food products at lower costs,but also causing many devastating

side effects.The large,concentrated animal populations in the Unite States produce around one hundred and sixty million tons of fecal waste
