people worry about it. However‚ the population on the earth has hit 6.5 billion. Some people are very worried about the ability of the world to sustain these huge numbers. This essay will examine the problem of overpopulation and suggest some ways of solving the problem. The biggest and major problem is rapid increase in the number of people. If the world population continued to grow at the current rate‚ the earth would not be able to sustain its population and the number of people will decrease

Population ecology is the branch of ecology that studies the structure and dynamics of populations. In population ecology a population is a group of individuals of the same species inhabiting the same area. In contrast to genetics‚ where the population is a group of interbreeding individuals of the same species‚ which is isolated from other groups and in human demography‚ the population is the set of humans in a given area. Population density is a common biological measurement and is often used

Kevin Webb 5/15/13 World population Many people have expressed great concerns about the rate of growth as well as the size of the world’s population. During the last 50 years‚ the world population has doubled rapidly more than ever before giving a global population of 7 billion. At the beginning of the population increase‚ there were many factors that caused it to grow. With the industrial revolution came advances in agriculture and industry that provided a way for individual families to be able

POPULATION RISE IN INDIA: A MOJOR CONCERN India has experienced extraordinary population growth: between 2001 and 2011 India added 181 million people to the world‚ slightly less than the entire population of Brazil. But 76 per cent of India’s population lives on less than US$2 per day (at purchasing power parity rates). India ranks at the bottom of the pyramid in per capita-level consumption indicators not only in energy or electricity but in almost all other relevant per capita-level consumption

distribution of the world’s population. The world population is expected to grow from 6.1 billion in 2000 to 8.9 billion in 2050‚ increasing therefore by 47 per cent. The changing distribution‚ rate and nature of the world’s population consider a number of factors which include urbanisation‚ population of the developing and developed countries. Also how fast or slow the population increases over a specific period of time‚ and where the distribution is and why. Population of developing countries

How china’s population has changed over time? China’s population is at once its greatest asset as well as its most significant challenge. This is as true today as the twenty-first century begins as it has been for much of China’s history. Although there are not absolutely reliable historical census numbers for China‚ certain patterns emerge as one examines China’s imperial demographic path from 60 million people two thousand years ago passing the one billion mark in recent times. China is world`s

First of all‚ population is not a very useful measure by itself simply because it fails to account for the size of the land in which the population resides. Some countries like Russia have a very large area while others like Singapore have a very small one. Therefore the appropriate indicator to use in order to make valid comparisons is population density (i.e.‚ population per unit of land area). Using this indicator one would find‚ for example‚ that Belgium has a very high population density‚ Pakistan

it is easy to see why its total fertility rate‚ life expectancy‚ total population‚ and other demographic identities have changed over the past century. Even with its TFR well below replenishment level‚ their population has continued to grow until recently when the growth rate has decreased and actually turned negative to -.077% (CIA 2012). It is noticeable the effects of WW1‚ WW2‚ and the Korean War have had on its population. During each of these wars the TFR dropped at the start of the war‚ slightly

Europe and Russia have experienced population declines over the last couple of decades. The birth rate decline has led Europe to what today is an aging population. Although a lower birthrate is not necessarily a bad thing‚ this creates an uneven population. Everything in nature is good in moderation and when it comes to nature and humans‚ homeostasis is key. If you have the baby boomer population all aging at the same time and a low birthrate‚ this can negatively affect Europe and Russia socially
