Contrary to Malthus' s arguments, human foodproducing capacity has increased more rapidly than human population. Yet, agricultural advances often compromise biological diversity. Ttherefore, Malthus' s prediction that insufficient food will doom humanity to war, pestilence, and famine will likely be proven correct in the future, because a lack of biodiversity will eventually erode our capacity to produce food.
The statement that human food-producing capacity has increased more rapidly than human population plays the role of a general fact that the argument offers reason to believe will eventually change.
