"Who gives a hoot about habitat?"

Hippos Composite Population Graph

Hippos once numbered in the hundreds of thousands or more. Numbers of hippos in the wild are currently estimated by ecologists to be in the single digit thousands. That works out to a SANI value of about one. The subpopulations are fragmented but somewhat above Minimum Viable Population levels. Their survival is dependent upon the maintenance of their watery habitat. This condition exists because the regions of Africa in which these organisms previously found habitat is overpopulated by humans. Global warming is expected to deal a disproportionately severe blow to the continent of Africa relative to other continents. If the habitat of the hippos undergoes significant dessication humans may be willing and able to artificially provide water. That the human social and political climate would be amenable to an indefinite continuation of such efforts is not a given.

Conservation of hippo numbers must be undertaken in order to preserve the illusion that humans have not overpopulated the planet.

This little graph shows the increase in human numbers in the last few thousand years. In this case, the distance from 1,000 million to 7,600 million is 7.6 times the distance from zero to 1,000 million. 7.6 billion is demographers' mid projection. Graph curve is from Learning Tools, KQED TV, San Francisco, a PBS educational tv station. Overpopulation denialists right and left have asked about the source, so now you know. The leader of the Task Force on Amphibian Decline living in Britain objected calling the graph extreme and, "off the scale." But it isn't. It is simply demographer's mid projection.

Usually when such a graph is drawn, a short time scale is used. But an evolutionarily significant time scale can more easily show relevant amounts of increase per unit of time.

The distance from 1,000 million to 7,600 million is 7.6 times the distance from zero to 1,000 million. The graph is an accurate representation.

Some Buddycom members have been watching and enjoying KQED since the sixties. Some have even been charter members of the station. Now you can see why. And you can get some idea of why the rightists wanted to use leaner budgets after tax cuts as a means of defunding the PBS.
Fraid not, jellybean.
Get back to Kansas where evolutionary time need not be considered. The state legislature has legally sactioned ignorance.
