Any scientific studies these days should be taken with a grain of salt, because we are without a doubt living in an era of soviet style science, where state and corporate entities are using the scientific establishment to project a particular worldview into the mainstream consciousness. This is why it is important to always look for funding sources and seek many different avenues of research.
However, every now and then there is a study to come out of the academic establishment that seems to coincide with reality. Even then we should still think critically about whatever information we are taking in.
Recently, one of those studies did manage to crack through to the mainstream, in relation to “overpopulation”, the belief that there are too many people in the world to lead a sustainable existence. However, there is more than enough room for plenty more people on this earth, it is just all of the violence and subjugation that has this planet trapped in a situation of scarcity.
Nature World News reported that:Overpopulation may not be such a big threat after all: using global population data from 1900 to 2010, scientists have developed a mathematical model showing that the number of Earth’s inhabitants may level off in the next 40 years. Conducted by a team of researchers from the Autonomous University of Madrid and CEU-San Pablo University, the numbers correspond with the lower estimates developed by the United Nations, which fall as high as 15.8 billion by 2100 in the case of high fertility and as low as 6.2 billion given low fertility.
The study, published in the journal Simulation, considered the Earth as a closed and finite system in which migration did not alter the principle of the conservation of mass (in this case people) and energy is fulfilled, according to a press release. Furthermore, it adjusted for the possibility of moving between zones of the two-level system, which is to say researchers took into account the fact that periods of high and low fertility may alternate over the next several decades.
“Within this general principle, the variables that limit the upper and lower zone of the system’s two levels are the birth and mortality rates,” UAM researcher and study co-author Felix F. Muñoz explained.
Describing the past, Muñoz said, “We started with a general situation where both the birth rate and mortality rate were high, with slow growth favoring the former, but the mortality rate fell sharply in the second half of the 20th century as a result of advances in healthcare and increased life expectancy and it seemed that the population would grow a lot. However, the past three decades have also seen a steep drop-off in the number of children being born worldwide.”
