Some salient features of the Malthusian theory are:The size of the population remains the same throughout the year but it is only changed to some extent in some seasonal changes. Nature is the chief controlling factor over the population of the area. To control the population, nature introduces certain factors like diseases, food shortages, calamities which influence the population size. The natural resources of nature are the forest, water, air, and food and designed in such a way that they are very limited in their number. So if we overexploit these resources then we are at risk of affecting the population and also the environment. This theory states that it is an inherent capacity of the population to expand in an exponential manner. So, as and when the reproduction takes place and the individuals also attain their reproduction phase then the size of the population can increase in an exponential way and this is checked by the factors that we discussed above.
