4), we can see that in both cases the population had reached the end of its sigmoidal growth, stabilizing their populations in the value of their capacity, 5 million in the case of England and 35 million in the case of Japan (K1).The Industrial Revolution began in England in the mid-eighteenth century and Japan in the second half of the nineteenth century, substantially increased the capacity (K2) to current levels, causing a rapid increase in population in both cases, to the new level (Meyer & Ausubel 1999.Especially with the industrial revolution energy costs soared and a strong increase of knowledge which subsequently led to the green revolution began, all of which produced an exponential growth of the human population.This past success leads to much of humanity to think that future increases in knowledge and technology now can not imagine allow indefinitely increase the capacity , or at least we are far from a maximum load.Carrying Capacity: A Model with Varying Logistically Limits ). Evolution of the population of England and Japan in recent centuries.Note that the shorter duration of the industrial revolution in Japan (77 years) due to be later, it corresponds to a growth in population correspondingly faster. We can see how the lifting capacity (K, inferred) results in the increase of population (P million) according to a sigmoidal curve to stabilize at the new value. Numerous studies can relate the increase in capacity in human populations with increased food availability .
The concept of carrying capacity also applies to human ecology .

The question of whether or not overpopulation in the world is clearly debatable.
Experiments in natural areas under management by government agencies show that populations are limited by the medium.
Essentially the availability of food, but also to a lesser extent by other factors such as water, shelter and space (see for example: Carrying Capacity – How many deer can we Have? Populations living therefore tend to fluctuate naturally around a certain level which is defined as its charge capacity.
