| Quote (Indiumas @ Nov. 23 2011,04:57) | If I may, I would like to comment a bit on the population dynamics issue discussed here. I have been discussing similar things with some local creationists here a few years ago.
Poplulation dynamics can be modelled with simple exponential growth only when the population is much smaller than the maximum value that can be sustained in a given environment. Once populations get closer to the maximum capacity the rate of change drops, eventually even to or below zero. This is also true for our times. See this report, for example.
Populations can be much better modelled using logistic functions with time varying capacities. Sometimes there might also be feedback loops between the number of people and the quality of the environment, or predator/prey relationships which further complicate matters. But the main point stands: For each environment and technological level there will be a maximum sustainable population.
Hunter and gatherer populations are estimated to have a maximum density of about 1-100/100km^2. Africa, for example, has an area of about 30 million km^2. Estimated historical populations are in good agreement with these numbers. Over long periods of time there was no possibility of exponential growth simply because the maximum carrying capacity was more or less reached. Only when humans invented a new technology that improved the maximum sustainable population (agricultuture, industrial revolution), there was/is a short period of exponential growth.
So, forastero, go away with your stupid exponential growth equations. As documented in this thread are not even able to handle the extremely simple mathematics behind them anyway. |
US scholar Albert Bartlett pointed out the difficulty to grasp ramifications of exponential growth, stating: "The greatest shortcoming of the human race is our inability to understand the exponential function."[1] and what you and others apparently fail to understand is that any steady percentage growth is an exponential function and therefore an exponential curve. http://www.youtube.com/watch?v....2rkpBSY
Using your numbers, 100/100km breaks down to about one person / .5 miles^2 and if Africa is 30 million km^2 or 11583064 mi^2 then that would leave room for the exponential growth of over 23166128 hunter gatherers.
Carrying capacity augmented by agriculture is a good point and just one more reason why humans and animals cant be easily compared. The problem with evolutionism is that assumes fellows like erectus were brutes, when in reality; he hunted big game, was very adept to exploring both land and sea. There has always been both hunter gatherer and farmer and there always will be. Heck, its now known that even the tropical rainforests have been heavily manipulated by prehistoric hunter gatherers who practiced agroforestry. The Bible tells us that Adam’s children were agriculturist. Modern archeological and ethnohistoric evidence indicates that Prehistoric Amerindians, aborigines, etc... experienced exponential growth. I also provided several links that disagree with you.
The U.N. is the epitome of corrupt big government and directly funds (UNFPA) various programs within the totalitarian Chinese government, which controls family planning (forced abortions and infanticide), church, and the teaching of human evolution with a politically biased slant?
The only reason that the U.N. makes the claim of stabilization is so certain sheople will believe that their brand of education and family planning is actually working. “China has had the most successful family planning policy in the history of mankind in terms of quantity and with that, China has done mankind a favour,” said United Nations Population Fund (UNFPA) representative Sven Burmester
The U.N. claims that Co2 breathing is an environmental tax that needs to be controlled via what amounts to climate colonialism?
Forced abortions, mass sterilization and a“Planetary Regime” with the power of life and death were all core concepts put forth by John P. Holdren, adviser to President Barack Obama for Science and Technology. In fact, Holdren’s ideas pre-date the inception of China’s one child policy by two years
To The Global Elite The Math Is Simple: Human Overpopulation Is Causing Climate Change So The Solution To Climate Change Is Population Control http://thetruthwins.com/archive....control

This dude covers it in a nutshell pretty well
The U.N. lust for Africa's unique resources, flora, fauna and thus blames its population for Saharan desertification. The U.N. propaganda is full of charts and images showing how African population levels are responsible for European heat waves, sandstorms and dust clouds that supposedly leads to everything from global warming to European forest fires to a global spread of pathogens.
.The Zero Population Growth movement that is alive and well within the United Nations and NASA, upheld Margret Sanger, Rachel Carson, Margaret Mead, and Marie Equi as their idols. These and other all radical antichristian were hell bent on population control with actions that lead to hundreds of millions of deaths and murders-- mostly Africans and Afroamericans and Latinos. Sanger's Planned Parenthood, for instance has its origins in racists motivated eugenics and abortion and it still is.

Rachel Carson sounded the initial alarm against DDT, but represented the science of DDT erroneously in her 1962 book Silent Spring. The EPA banned DDT in 1972 . This same inept EPA that Obama has recently given total environmental sway in the U.S. and even much of the world with its overpopulation equals CO2 induced global warming. Since the EPA banned DDT, an estimated 15 billion cases of malaria have caused immense suffering and poverty in the developing world. Of these largely avoidable cases, over 101 million people died. the World Health Organization (WHO) believed that the only alternative to the overpopulation problem was to assure that 40% of the children in poor nations would die of malaria. An official of the Agency for International Developmenteven stated,"Rather dead than alive and riotously reproducing." Desowitz, RS; 1992; Malaria Capers. Alexander King, co-founder of theClub of Romesaid (9),"In Guyana...it [DDT] had almost eliminated malaria, but at the same time, the birth rate had doubled. So my chief quarrel with DDT in hindsight is that it greatly added to the population problem."
In his Environmentalism as a Religion, Michael Crichton stated:"I can tell you that DDT is not a carcinogen and did not cause birds to die and should never have been banned. I can tell you that the people who banned it knew that it wasn’t carcinogenic and banned it anyway. I can tell you that the DDT ban has caused the deaths of tens of millions of poor people, mostly children, whose deaths are directly attributable to a callous, technologically advanced western society that promoted the new cause of environmentalism by pushing a fantasy about a pesticide, and thus irrevocably harmed the third world. Banning DDT is one of the most disgraceful episodes in the twentieth century history of America. We knew better, and we did it anyway, and we let people around the world die and didn’t give a damn." http://climaterealists.com/index.p....id=2049
