 * 04-Dec-1998: New "savers" added for hiv, veg, and lab.
 *              hiv one due to Kenneth Stailey <kstailey@disclosure.com>
 * 10-Aug-1998: Population Explosion and Tropical Forest Countdown stuff
 *              I tried to get precise numbers but they may be off a few

/*-
 *  Some of my calculations laid bare...  (I have a little problem with
 *  the consistency of the numbers I got at the Bronx Zoo but proportions
 *  were figured to be 160.70344 people a minute increase not 180 and
 *  35.303144 hectares (87.198766 acres) a minute decrease not 247 (100 acres).
 *  So I am going with these more conservative numbers.)
 *
 *  Time 0 is 0:00:00 1 Jan 1970 at least according to hard core UNIX fans
 *  Minutes from 1  Jan 1970 to 21 Jun 1985:  8137440
 *  Minutes from 21 Jun 1985 to 12 Jul 1988:  6867360
 *                                    Total: 15004800
 *
 *  Population Explosion Saver (popex)
 *  3,535,369,000 people (figured by extrapolation) 1 Jan 1970
 *  4,843,083,596 people 21 Jun 1985 (Opening of Wild Asia in the Bronx Zoo)
 *  5,946,692,000 people 12 Jul 1998 (David Bagley visits zoo ;) )
 *  180 people a minute increase in global population (I heard 170 also)
 *  260,000 people a day increase in global population
 *
 *  Tropical Forest Countdown Saver (forest)
 *  1,184,193,000 hectares (figured by extrapolation) 1 Jan 1970
 *    (2,924,959,000 acres)
 *  896,916,700 hectares 21 Jun 1985 (Opening of Wild Asia in the Bronx Zoo)
 *    (2,215,384,320 acres)
 *  654,477,300 hectares 12 Jul 1998 (David Bagley visits zoo ;) )
 *    (1,616,559,000 acres)
 *  247 hectares a minute lost forever (1 hectare = 2.47 acres)
 *
 *  HIV Infection Counter Saver (hiv) (stats from http://www.unaids.org/)
 *  33,600,000 31 Dec 1999 living w/HIV
 *  16,300,000 31 Dec 1999 dead
 *  49,900,000 31 Dec 1999 total infections
 *   5,600,000 new infections in 1999
 *  10.6545 infections/min
 *  -118,195,407 virtual cases (figured by extrapolation) 1 Jan 1970
 *   (this is a result of applying linear tracking to a non-linear event)
 *
 *  Animal Research Counter Saver (lab)
 *  Approximately 17-22 million animals are used in research each year.
 *  OK so assume 17,000,000 / 525960 = 32.32184957 per minute
 *  http://www.fcs.uga.edu/~mhulsey/GDB.html
 *
 *  Animal Consumation Counter Saver (veg)
 *  Approximately 5 billion are consumed for food annually.
 *  OK 5,000,000,000 / 525960 = 9506.426344209 per minute
 *  http://www.fcs.uga.edu/~mhulsey/GDB.html
