Some subscribers to Math-Teach might be interested in a recent post "Sad News About Al Bartlett" [Hake (2013)].  The abstract reads:

ABSTRACT: In a disturbing discussion-list post, Al Bartlett <http://bit.ly/19jfGEU> wrote that his non-Hodgkins Lymphoma, previously dormant, has returned such that doctors give him "30 days, plus or minus." As a tribute, it may be appropriate to publicize one of Al's latest attempts to emphasize the crucial but under-appreciated importance of *overpopulation*.

In his pungent "Population Press" letter "Close the Fire Department!" soon to be online at "Population Press" <http://populationpress.org/>, Al describes his experience at a recent AAAS symposium on sustainability where a panelist, in answer to his question as to why the obvious benefits of reducing our present overpopulation were never mentioned, explained that "United Nations figures show that the growth rate of world population is declining and world population growth is expected to stop on its own later in the century. So the population is under control and there is no need to worry ourselves about it at this time."

Al responded by inviting the panelist to come with him to City Hall and seek to convince city government that it doesn't need a Fire Department since it's an established fact that all fires will eventually go out!

"The greatest shortcoming of the human race is our inability to understand the exponential function."
    - A.A. Bartlett

" 'Sustainable growth' is an oxymoron."
    - A.A. Bartlett

"Smart growth destroys the environment. Dumb growth destroys the environment. The only difference is that 'smart growth' does it with good taste. It's like booking passage on the Titanic. Whether you go first-class or steerage, the result is the same."
    - A.A. Bartlett

"Can you think of any problem in any area of human endeavor on any scale, from microscopic to global, whose long-term solution is in any demonstrable way aided, assisted, or advanced by further increases in population, locally, nationally, or globally?"
    - A.A. Bartlett
