The Four Steps to the Sky

Without constraints, the population grows exponentially (ie: 2, 4, 8, 16, 32, 64, 128, etc.).

The food supply shows a linear (ie: 1, 2, 3, 4, 5, 6, 7, etc.) increase.

Food is the most important condition for human survival.

Only natural causes (accidents and old age), disasters (wars, plagues, and famines of all kinds), moral limitations, and crimes (by which Malthus included infanticide, murder, birth control, and homosexuality) could limit excessive population growth.

Malthus noted that many people misapplied his theory, painfully stating that he did not merely predict future cataclysms.He argues that the reasons for the persistence of periodic catastrophes have existed since human history, still exist, and will continue to exist in the future unless there is a decisive change in the physical structure of our nature.

Therefore, Malthus regarded his "Essay on Population" as an explanation of the past and present conditions of mankind, as well as a prediction of our future.

The argument of the population theory The food increase will only be in an arithmetic progression, but the population increase will be in a geometric progression.Therefore, he felt that human beings must worry about the lack of food, and reduce the preventive restrictions on marriage, as well as the positive restrictions imposed by the oppression of the already born population due to the torment of real poverty.

Pastor Thomas, Robert, Malthus (1766-1834), generally called Thomas, Malthus, although he liked to call himself Robert, Malthus.was a British demographer and political economist.His academic thinking was pessimistic but far-reaching.

The main point of Malthus's "Thesis of 1798": the number of people is severely limited by the means of subsistence.When the means of subsistence increase, the population increases accordingly.Population pressure stimulates growth.Growth in growth in turn stimulates population growth.

In the long run, growth cannot keep pace with the growth potential of the population, and there will be a huge gap between the population and the ability to support it.

Many factors that affect population and productivity, such as "sex", labor and children, are affected by individual income and expenditure decisions.Positive disincentives come into play when the population grows beyond the capacity to support it.The nature of these inhibitors will have implications for the rest of the biosocial system.
