module32REVIEW

In this module, we have seen that modern, large-scale farming methods have transformed agriculture. Large amounts of fossil fuel energy and fertilizer are common inputs to most agriculture in the developed world. The Green Revolution introduced a number of changes to agriculture in the 1950s and 1960s that continue to result in increased agricultural yield today. Genetic engineering has also changed agriculture, but it remains controversial. Animals are typically raised in concentrated feeding areas that allow for maximum profit but can result in a variety of environmental concerns. Fishery production is also dependent on modern mechanized systems that have resulted in increased yield at the expense of the wild populations.
