Question

describe in brief the main postulate of malthusian theory​

Answer 1

Answer:

Malthusianism is the idea that population growth is potentially exponential while the growth of the food supply or other resources is linear, which eventually reduces living standards to the point of triggering a population die off. This event, called a Malthusian catastrophe (also known as a Malthusian trap, population trap, Malthusian check, Malthusian crisis, Malthusian spectre, or Malthusian crunch) occurs when population growth outpaces agricultural production, causing famine or war, resulting in poverty and depopulation. Such a catastrophe inevitably has the effect of forcing the population (quite rapidly, due to the potential severity and unpredictable results of the mitigating factors involved, as compared to the relatively slow time scales and well-understood processes governing unchecked growth or growth affected by preventive checks) to "correct" back to a lower, more easily sustainable level. Malthusianism has been linked to a variety of political and social movements, but almost always refers to advocates of population control.

Answer 2

Answer:

The Malthusian Theory of Population is the theory of exponential population and arithmetic food supply growth. The theory was proposed by Thomas Robert Malthus. He believed that a balance between population growth and food supply can be established through preventive and positive checks.Major Elements of the Malthusian Theory

Population and Food Supply

The Malthusian theory explained that the population grows in a geometrical fashion.

Checks on Population

When the increasing population rate is greater than the food supply, disequilibrium exists.

Positive Checks

Nature has its own ways of keeping a check on the increasing population. It brings the population level to the level of the available food supply.

Preventive Checks

The preventive measures such as late marriage, self-control, simple living, help to balance the population growth and food supply. These measures not only check the population growth, but can also prevent the catastrophic effects of the positive checks.
