PERSPECTIVES ON POPULATION GROWTH Based on the current trend‚ there will be a total to about 9.2 billion people on the earth by mid-century‚ fuelled by the birth of 220000 children a day and falling mortality rates (Population Institute‚ 2014). This estimate raises questions about the future of humanity and the planet we inhabit. The debate about an optimal size for human population is one that has waged over the years. The question is fundamentally about sustainability; whether the resources that

Many people (including national leaders) worry that population growth depletes resources and can trigger social or economic catastrophe if it is not contained. As discussed in the preceding section‚ most of the projected population growth during this century will take place in developing nations. These countries have faced many challenges in recent decades‚ including low levels of education‚ poor health standards‚ poverty‚ scarce housing‚ natural resource depletion‚ wars‚ and economic and political

Human Population Growth Matt Lindsey SCI 230 Mayra Colombani July 27‚ 2012 Human Population Growth No matter what organism you are talking about‚ all living things possess the ability to reproduce. This comes in two forms. The first form of population growth is Exponential Population Growth. The second is Logistic Population Growth. Exponential population growth refers to when a population is not subject to any limiting factors‚ it will grow and expand exponentially even past the capacity

INTRODUCTION - POPULATION GROWTH The world experienced dramatic population growth during the twentieth century‚ with the number of inhabitants doubling from 3 to 6 billion between 1960 and 2000. India‚ too‚ saw very rapid population growth during this period – from 448 million to 1.04 billion – and to 1.21 billion in 2010. The effects of past and projected future demographic change on economic growth in India is the main focus of this chapter. Figure 1 plots world population from 1950 to

OVERPOPULATION Thesis statement: Overpopulation occurs when there are not enough resources on the earth to support its population. So it is one of the huge problems that our planet is facing it.The human population is increasing rapidly for many reasons. We can say that the problem of overpopulation started since the industrial revolution‚ because the industrial revolution helped people in finding more jobs‚ with a very good wages or pays‚ this increase in payment made people get more children‚

number of factors that can contribute to the growth of a population and these trends can be seen in a number of species. It is generally believed‚ from an ecological perspective‚ that populations will display either an exponential of logistic growth rate. If optimal environments are consistently maintained with no biotic or abiotic limiting factors (excess food‚ excess space availability‚ optimum climactic environment‚ no predation‚ etc) then a population will grow in an exponential direction.

POPULATION GROWTH AND CONTROL Population is considered to be an important asset for any country for growth rate of any country is greatly dependent on the people living in that country. But when it starts growing without any proper proportion then it becomes a menace for that part of part of the world.
