In my opinion one of the best independent sources for information about information is Joel Cohen, head of the Laboratory of Populations at Rockefeller University and author of How Many People Can the Earth Support?
Surfing the web the other day I came across a summary of an article Cohen wrote for Discover magazine, “Dispelling Common Population Myths Is First Step in Addressing Overpopulation.” Several of the myths Cohen mentions are de riguer for most of the people on the Internet who worry about population.
The first myth Cohen dispels is the idea that human population grows exponentially it doesnt (the amount of time it takes world population to double, for example, has declined significantly since the mid-1960s).
Cohen does an excellent job of puncturing a lot of the nonsense about “carrying capacity” which is a far more complex (in many ways almost unintelligible) concept than anti-population zealots imagine or will admit. Cohen has an excellent discussion of the problems involved with the “carrying capacity” concept in his book.
He also defends the Roman Catholic Church against the sort of bigots who claim that religions teachings are responsible for the population problem.
If only overpopulation zealots would start reading books and articles by mainstream demographers and population experts rather than getting all their materials secondhand from people with little formal training in population issues (can someone say Paul Ehrlich and Lester Brown?)
