Abstract

Human Population is one great issues nowadays in terms of economic crisis . The law of supply and demand is always at hand when we talk about population . Unavoidable change in the environment occurs as population goes higher . There are various factors that determine the change in population size . Causes of Human Population to increase will also be determined as to whether it impacts something good or bad in the culture of ones country . As population rise

, effects on culture economy , education , health care and services is expected . In a urbanized country , the government tries to find ways and set policies to handle this issue . People in rural areas is also given proper attention so that proper information will be disseminated in an educated manner . There are instances that population growth arises and from here environmental problems specially on the urban areas takes place . The rapid increase in world population should be put into priority of every citizen in the world . The future and stabilization of ones economy lies on the hand of people ones they decide to make the population count explode . The balance of nature is at hand sine human population growth is related to natural resources depletion and environmental degradation . Some country around the globe finds way to solve this problem in human population . In China the one child policy is what they think the best way to handle this issue . While in some country abortion has been legalized to solve overpopulation . But in the end of it all family planning is still the best way to solve this global issue of human population

Human Population

Defining Human Population

Population is defined in the field of biology and sociology as the collective number of individuals of a particular species . This species that belongs in a particular population shares the same kind of interest and inhabitation at a given geographic area

Human Population is defined through characterizations of family planning , mortality , migration , marriage and divorce in the family public health , work and the labor force

Another definition of human population is cited on Britannica website as

In human biology , the whole number of inhabitants occupying an area (such as a country or the world ) and as with any biological population the size of a human population is limited by the supply of food , the effect of diseases , and other environmental factors . Human populations are further affected by social customs governing reproduction and by the technological developments , especially in medicine and public health , that have reduced mortality and extended the life span (Population , 2008

Human Population and Demography

Demography is defined as the study of human population . This furthermore examines the population phenomenon and the statistical regularities attributed to the increasing human population . Demography casts a multidisciplinary net , drawing insights from economics sociology , statistics , medicine , biology , anthropology , and history . Its chronological sweep is lengthy : limited demographic evidence for many centuries into the past , and reliable data for several hundred years are available for many regions . The present understanding of demography makes it possible to project (with caution ) population changes several decades into the future (Population , 2008

Studying population provides insights into some of the processes that affect the growth of human populations . Understanding human population change is vital because the size of human population is central to most environmental problems and their solutions (Population Ecology ,

Factors affecting change in Human Population

Population of various organisms , whether sunflowers , eagles or humans ,change over time . On a global scale , this change is brought about by two factors : the rate at which individual organism produce offspring (the birth rate ) and the rate at which individual organism die (the death rate ' While in the local scale like the population in the Untied States , the number of births , deaths , immigrants and emigrants affect the population size (How Population Change in Size ,

Birth Rate and Fertility

Hence the study of demographic change requires knowledge of fertility (births , mortality (deaths , and migration . These , in turn , affect not only population size and growth rates but also the composition of the population in terms of such attributes as sex , age , ethnic or racial composition , and geographic distribution (Population , 2008

Birth Rate is measured by the number of live births per 1000 a year Birth rates are affected by such factors as nutrition , fertility attitudes about abortion , labor value of children , government policies social value , the availability of contraception and culture (Factors Affecting Population Change , 2008

Fertility is largely controlled by economics and by human aspirations The high fertility of the developing world can be partially explained by the large number of hands needed to perform low-technology agricultural tasks . In these areas , families with large numbers of children realize an enhanced economic status . As technology improves , parents realize that having more children decreases rather than increases their standard of living . A dramatic example of this effect occurred in Thailand where , as soon as parents realized that future economic status was linked to the secondary schooling (which is expensive in Thailand , the fertility rate dropped from about 6 to 2 in a decade (Population Growth 2006

Death Rate and Mortality

Death Rate is measured by the number of deaths per 1000 a year . Death rates are affected by disease , war , medical technology , improved health care , transportation development and nutrition (Factors Affecting Population Change , 2008

Another factor affecting human population is the number of Immigrants moving into a country . This is because there is a pull factor that attracts people to go to that place because of its distinct characteristics

Emigration is determined by the number of people leaving a country there are two factors involved here , first is the Push Factor or the characteristics of a place that causes people to leave . Second are the refugees wherein there are people who are forced to leave their country due to war , life-threatening discrimination , famine , or natural disasters (Factors Affecting Population Change , 2008

Human migrations have been fundamental to the broad sweep of human history and have themselves changed in basic ways over the epochs . Many of these historical migrations have by no means been the morally uplifting experiences depicted in mythologies of heroic conquerors explorers , and pioneers rather they frequently have been characterized by violence , destruction , bondage , mass mortality , and genocide - in other words , by human suffering of profound magnitudes (Population 2008

Effects of Human Population

The continuous increase in human population resuylts to many changes in the world . it affects both human and environment . The rapid increase of human population is putting an incredible strain on our environment While developed countries continue to pollute the environment and deplete its resources , developing countries are under increasing pressure to compete economically and their industrial advancements are damaging as well . The demands that this growth places on our global environment are threatening the future of sustainable life on earth (Population , Foote , Ley , Palson and Shem-Tov , 1998

Humans also continue to put a great demand on the natural resources of our planet . Many non-renewable resources are being depleted due to the unrestrained use of fuel and energy . Many parts of the world also suffer from a shortage of food and water . The growth of population puts larger demands on our already limited resources . The environment on earth is suffering from the growth of global population . The depletion of resources and biodiversity , the production of waste , and the destroying of natural habitat are serious problems that must be addressed in to ensure that life on earth will be sustainable throughout the next century (Population , Foote , Ley , Palson and Shem-Tov , 1998

The increasing rate of population growth can have an alarming effect not only on the environment , but on humans as well . The past several decades have displayed the prominent social consequences incurred on the human race as a result of their growing populations (Population Foote , Ley , Palson and Shem-Tov , 1998 . Low living standard is a result of Overpopulation . Low quality of education is also one of the results of this population problem . Unemployment and outbreak of civil war is also the result of overpopulation

The effects on humans from over population differ based on the economic status of the country . The population increase in lower economic regions targets the "reproductive age classes " Even China , which has established policies regarding the number of children allotted to families will suffer an increase when the babies born prior to restricting policies reach child-bearing age . Economically higher regions are rapidly increasing their population with older aged people The increasing rates of population continue to have very harmful effects on the environment AND the humans themselves (Population , Foote , Ley Palson and Shem-Tov , 1998

Predicting Growth in Human Population

The Population project website states that the current world populations as of 3 :58 EST , January 28 , 2008 is 6 ,646 ,848 ,831 (Population Projet , 2008 . We can see here that population is being collective and the resources provided by the planet earth may not be sufficent to supply the needs of the inhabitants . A greater prediction by means of Demography srudy is needed to give more idea of how big will the population be in the future

Demographic change is inherently a long-term phenomenon . Unlike populations of insects , human populations have rarely been subject to explosion ' or collapse ' in numbers . Moreover , the powerful long-term momentum that is built into the human age structure means that the effects of fertility changes become apparent only in the far future For these and other reasons , it is by now conventional practice to employ the technology of population projection as a means of better understanding the implications of trends (Population , 2008

Once the population is projected by demographers it plays out a representation of the future and gives assumption about future fertilities , mortalities and migration rates . It cannot be stated too strongly that such projections are not predictions , though they are misinterpreted as such frequently enough . A projection is a what-if exercise based on explicit assumptions that may or may not themselves be correct . As long as the arithmetic of a projection is done correctly its utility is determined by the plausibility of its central assumptions . If the assumptions embody plausible future trends , then the projection 's outputs may be plausible and useful . If the assumptions are implausible , then so is the projection . Because the course of demographic trends is hard to anticipate very far into the future , most demographers calculate a set of alternative projections that , taken together , are expected to define a range of plausible futures , rather than to predict or forecast any single future . Because demographic trends sometimes change in unexpected ways , it is important that all demographic projections be updated on a regular basis to incorporate new trends and newly developed data (Population , 2008

What we can do on this growth in Human Population

Human population growth is typically treated as a natural phenomenon over which we have no control . The truth is that Human population is completely within our control . There are many conscious decisions we can make that will greatly affect the Human population (Human population is within our control , 2008

If you really want to contribute and help minimize the human population growth , family planning is one great factor to consider . You must first decide to have one or at least two children . It is simple arithmetic that if each couple has on average two children , they will exactly replace themselves with two humans and contribute to zero population growth . If on average each couple has less than two children , they will contribute to negative population growth (Human population is within our control , 2008 . If you wish to add more to your children you may opt for adoption to lessen the birth rate and contribute to the needs of other children being left out by their parents

Spread the word about the population project and creating a more aware human population . By addressing the problems and solutions at hand we can more effectively limit further population growth (Human population is within our control , 2008

Contribute to organizations that educate . Population growth rates are the highest in the poorest regions of the world . Although humans in these areas generally have a much smaller ecological impact than their western counterparts , it is still an important issue to address . It is nearly impossible for the average person to have an immediate effect on these regions , but anyone can contribute to the organizations that work in these regions (Human population is within our control , 2008

You can always do something and play an important role to help save humanity . Human population is one great issue that everyone should be sensitive . Our future lies in our hand and each people has social responsibility that will give a more stabilized economic growth
