U r true according to world history,religions.
We humans knows the history of world only 2500 years past by the proofs of incidents occurred world wide comparing with time and years….
Beyond that all our calculations are our assumptions.
For instance, the population of the human species is getting larger by every second, while our environment is running out of supplies to support our growing population.
Your projected estimates prove that human life did not begin some 200,000 years ago. The planet would be overrun with people. Also, the population growth was not stymied because of a lack of food. There is no evidence of that. People are assuming that. The assumption is either because of lack of food people have less kids, which is not the case now in any part of the world that is in short food supply. Or the assumption is that people died because they starved to death, which means we should find bodies all over the place, which we don’t. Birth rates slow in more technological societies than less. So, the birth rate was probably higher in the past. Given what we do know of birth rates and not what we can speculate, man has probably only been around 6000 years.
what was the world population 300 Million years back since Fossil fuels were formed from plants and animals that lived 300 million years back, I’m just curious what it takes to produce so much oil
A similar thought has not been letting me sleep. If we suppose that the human population was at 1 billion in 1 A.D, that is more than 7 times smaller than it is today just 2000 years ago. By doing the math and using the same ratio, the world population would just be 3-4 people in 20,000 B.C! Keep in mind that we really didn’t reach 1 billion up until the 1800s A.D and the realistic scientific estimates for the world population in 1 A.D max out at just 400 million. Also modern humans supposedly appeared between 1 to 200 thousand years ago. Something just really doesnt add up!
They have successfully controlled their population growth which population transition from high birth rate to low birth rates in a short period of time.
I recently built my family tree, on my mothers side alone the amount of people being born and reproducing were huge. My great-great grand parents had 15 kids, his son my great grand father had 12, his daughter my mother had 8 kids….two people, produced so much…and we are still growing….This is going back to the late 1800’s only and there are over one thousand decedents and this was a third world country (El Salvador) not the US. With that said I don’t believe these estimates…even with death, plagues, war and such the population had to increase rapidly….can anyone explain this?
is the third most populous country in the world and has the highest population growth rate of all developed countries,” ( Chamie 1) to further analyze this issue to put it in perspective of the global issue it actual is by comparing the United States current issue with population growth to the population growth issue...
10 generations and two became a billion. Yes death and plagues and famine would diminish this but look at the results and my estimates aren’t unrealistic….ten generations is as little as 350 years. So why is it that so many sites show between the years of 1 A.D. to 1500 the world population as staying relatively stable when people can produce like this?
It is also a reflection of the population growth trend continued in the post-World War II period characterized by rapid growth of several Southwestern metropolitan cities.
Question, to anyone who can answer. Why did the population between 1 A.D. and 1500 increase so slowly (or stayed relatively unchanged)? It does not make sense IMO. If we take the normal increases we see generation by generation especially giving the mortality rate of infants and death by other means it tells me that our population was much smaller 2000 years ago. India staying relatively unchanged for 1500 years does not compute. The tradition of all populations until the last century (for some societies only) at the time was large families, if parents had say 12 children and eight survived to have ten children each (again eight surviving) those original two would of increased to 64 withing one generation…and that trend would of continued to the point of those sixty four multiplying to over over 500….two generations have passed again using just eight surviving children and that amount is actually light considering some populations even today could have up to 15 children.
There was virtually no technological or social progress between 1 AD and 1500 AD or so – which is why the countries where people actually live weren’t able to feed a significantly increasing number of people. The progress, which existed in the Greco-Roman world etc., was only restarted with the renaissance etc. around 1500 AD which is when the population restarted the big growth.
According to Nasif Nahle, overpopulation is “a term that refers to a condition by which the population density enlarges to a limit that provokes the environmental deterioration, a remarkable decline in the quality of life, or a population collapse.” People often ignore the subject of overpopulation, but this predicament is the world’s leading problem that society is burdened with going into the future.
