The problem that there are more and more human beings on a finite earth
with finite resources.
original population problem was stated by Malthus, in the beginning of
the 19th Century: He claimed that human populations grow in a
geometrical series whereas resources grow in an arithmetical series, and
as the former grow faster than the latter, there is always bound to be a
large and poor lower class.
It seems that there is no evidence backing up his particular claim
and that such evidence as there is goes against it. Two reasons are that
food - plants, animals -multiplies in the same way as humans do, and
often faster, and that there also is human inventiveness: At the very
time Malthus was writing, there were important innovations in
agriculture and the industrial revolution was starting.
It is otherwise with the fact that the human population is rapidly
increasing, largely through the improvements in medicine and hygiene,
and the truth that the earth is finite and has finite resources, though
all of the latter may take a long time to find, and there still is human
Indeed, the basic population problems that I see are, first, that of
the many who are born so few are truly intelligent and of good will and,
second, that so many of those who live are so easily deceived and misled
by TV, propaganda, politicians, and religious leaders.
The only way out of human problems is by human
intelligence, but as
the human population grows it seems as if the proportion of truly
intelligent people who are willing and able to work in or for real
science grows less. And that seems to me the real population problem,
which does not inhere in some limits to growth as in the limited human
capacity to think rationally and behave reasonably.
