Additional energy was stored when carbon fromonce-living matter was buried, in ever-so-tiny increments, underthe surface of the earth-in deposits that became coal, petroleum,and natural gas as well as in sedimentary rocks containingcalcium and magnesium carbonates derived from shells. Programmability -- and the consequent capacity forextrasomatic adaptation -- have made it possible for human beingsto advance a very old evolutionary trend at a vastly increasedrate.

The system that sustains world population isalready under stress. But the history of life involvescompetition among species, with new species evolving and old onesdying out. But controlled fusion is still experimental, thetechnology for its commercialization has not yet been developed,and the first operational facility could not come on line muchbefore 2040 (browne, 1993, p. Malthus did not know that theuniverse is governed by the second law of thermodynamics he didnot understand the population dynamics of introduced species andhe did not appreciate that humans, having evolved long after theresource base on which they now rely, are effectively anintroduced species on their own planet. But fire remained the mostimportant source of extrasomatic energy, and it made possible thedevelopment of ceramics and metallurgy.

Unfortunately, worldwideimplementation of a rigorous program of birth control ispolitically impossible.

    In fact, the growth rate of the earths humanpopulation has already begun to fall (figure 5).
