Population checks must be implemented in order to sustain a society that cannot outgrow its food supply and the issues regarding insufficient amounts of food and poverty are one individual’s problem. The Earth’s food surplus cannot supply rapid population growth. The concept which Malthus introduces is the preventative check. Thomas Malthus’ idea of society implies that a society’s population is dependent on the men. A man should not try to have more children than he can support. If the man cannot supply his children with enough food they will die because all living beings need food to live. An individual man is attached to a woman later in life, it may prevent rapid growth in population. But of course, a man would never apprehend himself. Thomas Malthus explains that a high population is mans fault because the man does not observe the problems of other people. The positive checks theory shortens life naturally, thus lowering the population. Several concepts keep the community in balance, such as wars, plagues, famines, epidemics, and disease. The population can never be higher than the food supply because people need food to survive. Lastly, implemented population checks must be instigated in order to sustain a society with financial stability and enough food to supply the entire population.
