Those lacking education fail to understand the need to prevent excessive growth of population.

32. Excessive population growth diffuses the fruits of development over increasing numbers instead of improving living standards in many developing countries: a reduction of current growth rates is an imperative for sustainable development. The critical issues are the balance between population size and available resources and the rate of population growth in relation to the capacity of the economy to provide for the basic needs of the population, not just today but for generations. Such a long-term view is necessary because attitudes to fertility rarely change rapidly and because, even after fertility starts declining, past increases in population impart a momentum of growth as people reach child-bearing age. However a nation proceeds towards the goals of sustainable development and lower fertility levels, the two are intimately linked and mutually reinforcing.


Population Growth: Essay on Population Growth

neo-Malthusians argue that excessive population growth and massive poverty in LDCs have greatly damaged the ..

The author pointed to the expected results that would be occasioned by these alterations. The first one would see an increase in the cost of pensions. As more and more people hit the old age mark, the government is forced to set aside higher budgetary allocations for the sustenance of the pension schemes. Increased population trends among the aged group in developed countries acts to expose existing social security programs to pressures of social and political nature. Apart from the pension schemes, other programs such as the social security systems present in the United States of America could be exposed to various problems (mostly financially related) if no secure alternatives are considered. These problems could include increase in the taxation system, adoption of lower living costs, reduction in the associated benefits obtained by the working class, excessive borrowing patterns and prolonging of retirement ages to reduce the level of dependant adults. These problems could also be used as policies which could be adopted to minimize these effects.


Finally, neo-Malthusians argue that excessive population growth and massive poverty in LDCs have greatly damaged the ecological balance by deforestation and land degradation. Consequently, these countries suffer badly from a variety of environmental hazards. Such canard is made by developed countries who are to be condemned outright for destroying ecological balance.And through external growth. Having more births than deaths.

Part I: Unchecked Growth
a. What would have happened to your mice population without predation?
Without predation, the mice would continue reproduce causing an excessive amount of them in the grassland.
Part II: Predation by Hawks
b. What effect does predation have on the mice population size?
a. Predation regulates the population of mice and for as fast as they reproduce, predation is a must.
c. Are there any other factors that limit the growth of natural populations?
a. Diseases and natural causes can limit population. If a natural cause, i.e. a fire, destroys the mice food supply and shelter then that is limiting the natural growth rate.
d. Do all members of the population in your model get to reproduce in this situation (with predator present)? If not, what proportion?
a. Yes. All members of the population were able to reproduce with a predator present.
e. Are all individuals in the population in your model exactly the same? If not, how were they different?
a. No. They vary in the color of their fur.
f. Are all traits equally favorable in a particular environment? Explain.
No. Certain colors of the fur can better camouflage an animal from predators while other certain colors can make them much more visible.
g. In this situation (predator), is there a relationship between (1) the chance to survive and reproduce and (2) the traits an organism possesses?
a. Yes. If an animal has a fur color that blends better with the surrounding environme... The prospect of further growth to 10 billion by 2100, now projected by the United Nations, only causes additional alarm. But in the face of the concern that arose in the 1950s and 1960s, perhaps best exemplified by biologist Paul Ehrlich’s 1968 publication, The Population Bomb, an equally vociferous group arose to contest what it saw as the excessive alarmism of these neo-Malthusians, as they were called. Perhaps foremost among them was the late economist Julian Simon, whose book, The Ultimate Resource, reflected the thinking of many other economists, as well as most of the conservative political movement in his country and elsewhere.
