Rapid growth in global population

The population of 51 countries or areas is expected to be lower in than in To do so, the access to safe and effective family-planning services for needy people takes a crucial role.

Human overpopulation

Other innovations include antibiotics and chemotherapy, and low-cost ways of providing safe water supplies and adequate environmental sanitation in villages that in most other ways remain relatively untouched by modernization.

The kinds of mortality reduction that have actually occurred in the world have the effect, if fertility remains unchanged, of reducing rather than increasing the average age of the population. In the medium variant, global fertility is projected to decline further to 2. The time span varies roughly from 75 to years.

Calculations of this sort demonstrate without question not only that the current continued increase in the rate of population growth must cease but also that this rate must decline again. Overconsumption and Human impact on the environment Some more problems associated with or exacerbated by human overpopulation and over-consumption are: Over-population is defined as the condition of having more people than can live on the earth in comfort, happiness and health and still leave the world a fit place for future generations.

Among the industrialized countries, Japan and most of the countries of Europe are now growing relatively slowly—doubling their populations in 50 to years.

Either the birth rate of the world must come down or the death rate must go back up. Birth rates are now falling in a small percentage of developing countrieswhile the actual populations in many developed countries would fall without immigration.

Rapid Growth in Global Population

In general, the death rate appears to be affected more immediately and automatically by industrialization. These dependents create pressure to produce for immediate consumption only. Moreover, there are few remaining areas comparable to North and South America into which a growing population could move and which could provide rapidly expanding markets.

Population growth

How can the consciousness level of the people in the developed nations towards the population issue be heightened? The Conference also adopted the final draft of the World Population Plan of Action, which included policies to stabilize Rapid growth in global population growth.

Africa will experience the greatest percentage increase percent-from million today to million by the year The number of people in the world has risen from 4. Economic progress will be slower and more doubtful if less-developed areas wait for the supposedly inevitable impact of modernization on the birth rate.

Today, three of the five most populous countries in the world can be found within Asia, with India projected to surpass China as the most populous country in the not-too-distant future.

One important characteristic is rapid growth, which is the immediate consequence of the large and often growing difference between birth and death rates; the other is the heavy burden of child dependency which results from a high birth rate whether death rates are high or low.

The birth rate in was about 35 per 1, population and the average number of children ever born to women reaching age 45 was about five. According to United Nations projections, the world population will be between 7.

Among the least developed countries, where life expectancy today is just under 50 years, it is expected to increase to 66 years by — Do they have any role in making population policies? Even if the death rate were to fall to zero, at the present level of human reproduction the growth rate would not be much in excess of three and one-half per cent per year, and the time required for world population to double would not fall much below 20 years.

The population of the world has now surpassed 7 billion people, and it continues to increase at a quick rate. The second fastest growing population globally, residing within the country of Lebanonregistered an estimated growth of 5.

To recapitulate, a short-term increase in per capita income may be possible in most less-developed areas, even if the fertility rate is not reduced. For example, when death rates fell during the 19th and 20th century — as a result of improved sanitation, child immunizations, and other advances in medicine — allowing more newborns to survive, the fertility rate did not adjust downward, resulting in significant population growth.

Two spects of the situation of women which have received major attention, particularly in the context of population policy, are education and labor force participation.

The only important exception to this statement relates to Ireland, where the decline in the birth rate was brought about by an increase of several years in the age at marriage combined with an increase of 10 to 15 per cent in the proportion of people remaining single.

On the other hand, in an urban, industrialized society, children are less of an economic asset and more of an economic burden.

At the conference, the issue of how to slow the population growth was divided into two sides by developed nations and developing nations.Rapid population growth in impoverished nations presents unique obstacles as they strive for prosperity.

Elevated rates of growth in such countries also places a heightened burden on their governments, as they try to stretch their finite resources and infrastructure. Humans everywhere must understand that rapid population growth damages the Earth's resources and diminishes human well-being." These UN Habitat states in its reports that urbanization may be the best compromise in the face of global population growth.

The chart below shows that global population growth reached a peak in and with an annual growth rate of %; but since then, world population growth was halved. For the last half-century we have lived in a world in. This unit addresses: (1) the definition of overpopulation (2) the causes of rapid population growth, (3) the consequences of rapid population growth, and (4) ac-tions and strategies that can be developed to solve problems caused by overpopula-tion.

The main cause of rapid population growth is when there are more births than there are deaths, which is referred to as a natural increase. Other causes of rapid population growth include an increase in food production and distribution, improvement in public health and the elimination of many.

Washington, DC: The National Academies Press. doi: / Moreover, rapid population growth and a heavy burden of child dependency divert investment funds to less productive uses—that is, less productive in the long run. To achieve a given level of literacy in a population much more must be spent on schools.
