The value placed upon large families especially among under-privileged rural populations in less developed countries who benefit least from the process of development , the assurance of security for the elderly, the ability of women to control reproduction, and the status and rights of women within families and within societies are significant cultural factors affecting family size and the demand for family planning services. Even with a demand for family planning services, the adequate availability of and access to family planning and other reproductive health services are essential in facilitating slowing of the population growth rate. Also, access to education and the ability of women to determine their own economic security influence their reproductive decisions.

This brief statement of population problems indicates the pervasive and depressive effect that uncontrolled growth of population can have on many aspects of human welfare. Nearly all our economic, social, and political problems become more difficult to solve in the face of uncontrolled population growth. It is clear that even in the wealthier nations many individuals and families experience misery and unhappiness because of the birth of unwanted children.

Population Growth: Causes, Characteristics and Explosion of Population Growth

Human overpopulation or particularly human population overshoot refers to a human population being too large in a way that their society or environment cannot readily sustain them. It can be identified with regional human populations, but is generally discussed as an issue of world population. Overpopulation is argued to be the cause, due to demographic pressure, of overconsumption and subsequently overshoot. This leads to exceeding the carrying capacity of a geographical area and damaging the environment faster than it can be replenished. As such it is further argued that human overpopulation potentially leads to demographic push , depopulation , or even ecological or societal collapse and human extinction. Ehrlich describes overpopulation as a function of overconsumption, [1] arguing that overpopulation should be defined by depletion of non-renewable resources. Under this definition, changes in lifestyle could cause an overpopulated area to no longer be overpopulated without any reduction in population, or vice versa.

At the beginning of the nineteenth century, the total world population crossed the threshold of 1 billion people for the first time in the history of the homo sapiens sapiens. Since then, growth rates have been increasing exponentially, reaching staggeringly high peaks in the 20th century and slowing down a bit thereafter. Total world population reached 7 billion just after and is expected to count 9 billion by This paper first charts the differences in population growth between the world regions. Next, the mechanisms behind unprecedented population growth are explained and plausible scenarios for future developments are discussed.

The largest single threat to the ecology and biodiversity of the planet in the decades to come will be global climate disruption due to the buildup of human-generated greenhouse gases in the atmosphere. People around the world are beginning to address the problem by reducing their carbon footprint through less consumption and better technology. But unsustainable human population growth can overwhelm those efforts, leading us to conclude that we not only need smaller footprints, but fewer feet. Portland, Oregon, for example, decreased its combined per-capita residential energy and car driving carbon footprint by 5 percent between and

Population growth is the increase in the number of individuals in a population. Global human population growth amounts to around 83 million annually, [2] or 1. The global population has grown from 1 billion in to 7. It is expected to keep growing, and estimates have put the total population at 8.

Human overpopulation or human population overshoot refers to a human population that is too large to be sustained by its environment in the long term. The idea is usually discussed in the context of world population , though it may also concern regions.

The most spectacular demographic changes in the whole of human history are currently taking place on the African continent and this development is set to continue over the course of the coming decades. As Europeans used to stagnant population figures, we find it very difficult to grasp the consequences of a three per cent growth in population leading to an approximate doubling of the population every twenty years. In Terms of Demographics, Africa is a Special Case In sub-Saharan Africa, we witness a demographic development different from that of the other continents. Due to the upheavals and unrest caused by the slave trade, Africa is the only continent whose population virtually stagnated between and , increasing from some 80 to 95 million only. While growth rates were at a very low level elsewhere in the world during the same period, they still developed to a five-fold increase in population numbers in Europe and China.

 Ах ты, мерзавка! - крикнул он, скорчившись от боли. Сьюзан бросилась к двери, моля Бога, чтобы Стратмор в этот миг включил резервное энергоснабжение и дверь открылась. Увы, ее руки уперлись в холодное стекло.
