In a post
published in this blog in December 2015, Julio A. Gonzalo and I analyzed
the data on the world population provided in 2012 by the UN, along with their future
forecasts until the year 2100. A few months ago, the UN has updated those data
and forecasts with the figures
available in 2019. As seven years have elapsed, it is possible to compare the
forecasts made in 2012 with the real situation just now.

The dominant ideology dares to censor science
In one of the most read and controversial posts in this blog, What science says about human life, which had 92 comments in its Spanish version (so far the blog
record), I explained how, for purely ideological reasons, supporters of
abortion close the eyes to what science says, which asserts clearly (and has
done so for a century and a half) that the life of every human being begins in
the fertilization of the ovum by the sperm. Faced with this, abortionists insist
on making false statements like these: a fetus is
only a part of the mother’s body; a fetus is not a human being; a fetus is
nothing but a set of cells (so what are the abortionists?).

| A cover of The Lancet |
Denouncing one more step towards the ideological control of scientific
research, the British journal The Lancet,
second in impact factor in the field of Medicine, has published an
article accusing certain abortion NGOs and the government of the United
Kingdom of interference in scientific research.
The scientists signing the article are part of a team working for the London
School of Hygiene and Tropical Medicine, which undertook the evaluation
of a project aimed at reducing deaths due to
unwanted pregnancies in 14 countries in Africa and Asia (i.e. the
number of deaths caused by induced abortions). The project, which was allocated
£140 million in funding, was sponsored by the United Kingdom's Department for
International Development (DFID) and carried out by two major NGOs working on international
reproductive health (an euphemism hiding the word abortion, although those organizations don’t
hide it in their websites).

Catastrophes and catastrophism
![]() |
| Chernobyl disaster |
From time to time catastrophes
occur, usually unforeseen, sometimes causing tremendous damage. Let's look at
some relatively recent ones:
- July 28, 1976: Tangshan Earthquake (China), intensity 7.5 on the Richter scale. The official death toll was 249,419, though some say it was actually three times as big.
- December 3, 1984: Bhopal disaster, a leakage of methyl isocyanate from a pesticide factory that caused some 20,000 deaths and affected about 600,000 people.
- 26 April 1986: Chernobyl Nuclear Power Plant Disaster, which caused 31 direct casualties. It is estimated that the number of deferred deaths due to the effects of radiation could approach 80,000, although the estimates may not be reliable.

A global conspiracy?
![]() |
| Isaac Asimov |
In 1976, at
the peak of the pessimistic forecasts about the catastrophic rise in global
population, foreseen by the first report of the Club of Rome (1972), Isaac
Asimov published a science fiction short story (The
winnowing), which suggested a (highly unethical) way to stop
this catastrophic increase in population. This is the summary of the story:
In 2005, the unstoppable population growth causes famine
in the third world countries. To contain it, the world
authorities (the UN), controlled by the developed world, decide to apply a
triage to the world population. To do this, a scientist (who does not want to
do it, but is threatened with reprisals against his family) is ordered to
develop a protein, poisonous for 70% of the population, but harmless for the remainder,
depending on each individual DNA, so that its effects will be dramatic, but
random. The protein will be introduced in the food sent to alleviate famines, so
as to bring the world population down to more manageable levels. The project is
not applied exactly as planned, because the biologist who must develop the
protein gives it to eat to the world leaders without their knowing, so that 70%
of them will die. As the protein has been adapted to the scientist’s DNA, by
eating it he commits suicide, thus escaping the consequences of what he has
done.

Malthus’s mistake
![]() |
| Thomas Robert Malthus |
Since the end
of the eighteenth century, apocalyptic warnings as regards the unstoppable
increase of the world population have followed one another. In 1798, Thomas
Robert Malthus published An essay on the principle of population, as
it affects the future improvement of society, with remarks on the speculations
of Mr. Godwin, M. Condorcet, and other writers. This essay includes the
famous quotation:
Assuming then my postulata as
granted, I say, that the power of population is indefinitely greater than the
power in the earth to produce subsistence for man.
Population, when unchecked, increases
in a geometrical ratio. Subsistence increases only in an arithmetical ratio. A
slight acquaintance with numbers will shew the immensity of the first power in
comparison of the second.
