Fewer than million people populated the Earth in the mid th Century. Today, barely years later, we are more than 7. Taking into account the fact that human beings appeared on Earth more than four million years ago, what happened in our recent history for the number of inhabitants on the planet to start multiplying exponentially? The tipping point was generally accepted to be the Industrial Revolution, but there are many smaller revolutions that contributed to population take-off which have brought the planet to its current dangerous overpopulation : revolutions that are medical, technological, agricultural, financial, transport and demographical in nature, among others. China alone is home to 1.

Malthusianism is a controversial economic theory that sees fluctuations in human population as reasons for fluctuations in prices. Its general idea is that population growth is potentially exponential while the growth of the food supply or other resources is linear , which eventually reduces living standards to the point of triggering a population die off. This event, called a Malthusian catastrophe also known as Malthusian trap , population trap , Malthusian check , Malthusian crisis , Malthusian spectre , Malthusian crunch occurs when population growth outpaces agricultural production , causing famine or war , resulting in poverty and depopulation. Such a catastrophe inevitably has the effect of forcing the population quite rapidly, due to the potential severity and unpredictable results of the mitigating factors involved, as compared to the relatively slow time scales and well-understood processes governing unchecked growth or growth affected by preventive checks to "correct" back to a lower, more easily sustainable level. These concepts derive from the political and economic thought of the Reverend Thomas Robert Malthus , as laid out in his writings, An Essay on the Principle of Population. Malthus suggested that while technological advances could increase a society's supply of resources, such as food, and thereby improve the standard of living , the resource abundance would enable population growth , which would eventually bring the per capita supply of resources back to its original level. Some economists contend that since the industrial revolution , mankind has broken out of the trap.

If you create an account, you can set up a personal learning profile on the site. Figure 2. Growth is slow until the middle of the 20th century, when the gradient slope of the graph increases, indicating a change to more rapid population growth. The graph continues into the future to a predicted global population in in excess of 9 billion. There are many factors that influence this trend. High rates of infant and childhood deaths and short lifespans put a limit on population growth in the past. However, improvements in nutrition, water, medical care and other technological advances have contributed to a sharp decline in deaths while births continue to increase, resulting in population growth.

PIP: Rapid population growth is one of the major contributing factors to the poverty and under-development of Third World countries--especially African countries, which boast the highest population growth rates in the world. Several factors are responsible for the rapid growth: a drop in mortality rates, a young population, improved standards of living, and attitudes and practices which favor high fertility. Africans view large families as an economic asset and as a symbol of worth and honor, and parents see it as security during old age. The ideal family size in Africa is 5 to 7 children. Because of its complex causes, curbing the rapid growth is not easy.

Dear EarthTalk : To what extent does human population growth impact global warming, and what can be done about it? No doubt human population growth is a major contributor to global warming, given that humans use fossil fuels to power their increasingly mechanized lifestyles. According to the United Nations Population Fund, human population grew from 1. Think about it: It took all of time for population to reach 1. During that time emissions of CO2, the leading greenhouse gas, grew fold.

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.

Вы не скажете, где они могли остановиться. Клушар закрыл глаза, силы покинули. Он едва дышал. - Хоть что-нибудь, - настаивал Беккер.  - Может, вы знаете имя этой женщины. Клушар некоторое время молчал, потом потер правый висок. Он был очень бледен.

Сьюзан взяла себя в руки и быстро подошла к монитору Хейла. Протянула руку и нажала на кнопку. Экран погас.

Сьюзан понимала, что теперь это не имеет никакого значения. Нужно немедленно доложить обо всем Стратмору. Ирония ситуации заключалась в том, что партнер Танкадо находился здесь, прямо у них под носом. Ей в голову пришла и другая мысль - известно ли Хейлу, что Танкадо уже нет в живых.
