Malthusian Theory of Population (1978):
The English scholar Reverend Thomas Malthus published "An Essay on the Principle of Population." He wrote that overpopulation was the root of many problems in which society suffered from poverty, malnutrition, and disease could all be attributed to overpopulation.
In Essay on the Principle of Population, Malthus proposes the principle that human populations grow exponentially (i.e., doubling with each cycle) while food production grows at an arithmetic rate (i.e. by the repeated addition of a uniform increment in each uniform interval of time). Thus, while food output was likely to increase in a series of twenty-five year intervals in the arithmetic progression 1, 2, 3, 4, 5, 6, 7, 8, 9, and so on, population was capable of increasing in the geometric progression 1, 2, 4, 8, 16, 32, 64, 128, 256, and so forth.
According to Malthusian Population trap. Population increases geometrically (doubles, then again

Advantages Of Logistic Growth Model
1872 Words | 8 PagesThe first model, the exponential growth model, merely can only predict the future population. However, this is a very unrealistic model, as there environmental factors that may affect the population to grow exponentially. This can be seen in the general equation, as the variable K, which represents the carrying capacity, is not included. Therefore, the second model, logistic growth model, is more realistic, as it can be applied to real life situations for its considerations made on the carrying capacity of an environment. The [1 - (P(t))/K] included in the general equation shows how the logistic model recognizes that the environment has a limit to the amount of resources that can support a population.
