The Green Revolution saved millions of people from starvation. However, it also allowed the world population to increase exponentially during the same period. Some scientists have said that the Green Revolution has delayed the global food shortage problem rather than solving it. Provide FOUR plausible examples of how the Green Revolution/techniques can directly cause a future global food shortage (i.e., for each example, list one of the Green Revolution techniques and briefly explain how it can cause future food shortages)
