Not only this, but “we are running out of the two basic ingredients we need to grow food on an industrial scale: oil and water.” (Mckibben, 62) The situation has become so dire that “we are now facing a near simultaneous depletion of the underground aquifers which have been responsible for the unsustainable, artificial inflation of food production.” At this point of realization, Mckibben begins indulging the reader in a large number of facts that promote a more localized form of farming as the solution to a seemingly endless number of issues. Initially the point is raised that “sustainable agriculture leads to a 93% increase in per-hectare food production.” (Mckibben, 68) The next idea raised is that, “since World War 1, it has been cheaper to use…
