Since the emergence of the Malthusian theory there have been conflicting ideas about the size of populations relative to human wellbeing. There are different opinions regarding the idea that a large and rapidly increasing population is desirable as it provides the country with a source of wealth, while others believe that population growth is desirable up to a certain point. In contrast, some believe any increase in population will have damaging effects on society and will ultimately result in human misery such as starvation and famine. Thus, there have been strong contrary views about the problem of overpopulation. In short, it has been recognised that the problem of population growth and its size remains an important factor in the economic development of a country.
