The Smokies seem to be in the process of losing most of their mussels. The National Park Service actually has something of a tradition of making things extinct. Bryce Canyon National Park is perhaps the most interesting-certainly the most striking-example. It was founded in 1923 and in less than half a century under the Park Service's stewardship lost seven species of mammal-the white-tailed jackrabbit, prairie dog, pronghorn antelope, flying squirrel, beaver, red fox, and spotted skunk. Quite an achievement when you consider that these animals had survived in Bryce Canyon for tens of millions of years before the Park Service took an interest in them. Altogether, forty-two species of mammal have disappeared from America's national parks this century.

The very name of my subject, economics, suggests economizing or maximizing. But Political Economy has gone a long way beyond home economics. Indeed, it is only in the last third of the century, within my own lifetime as a scholar, that economic theory has had many pretensions to being itself useful to the practical businessman or bureaucrat. I seem to recall that a great economist of the last generation, A. C. Pigou of Cambridge University, once asked the rhetorical question, "Who would ever think of employing an economist to run a brewery?” Well, today, under the guise of operational research and managerial economics, the fanciest of our economic tools are being utilized in enterprises both public and private.
Paul Samuelson
One outcome of the Norman Conquest was the making of the English language. ...the speech of Alfred and Bede, was exiled from hall and bower, from court and cloister, and was despised as a peasant's jargon... It ceased almost, though not quite, to be a written language. ... Now when a language is seldom written and is not an object of interest to scholars, it quickly adapts itself in the mouths of plain people to the needs and uses of life. ...it can be altered much more easily when there are no grammarians to protest. During the three centuries when our native language was a peasant's dialect, it lost its clumsy inflexions and elaborate genders, and acquired the grace, suppleness, and adaptability which are among its chief merits.

It was in the attempt to ascertain the interrelationships between species that experiments n genetics were first made. The words "evolution" and "origin of species" are now so intimately associated with the name of Darwin that we are apt to forger that the idea of common descent had been prominent in the mnds of naturalists before he wrote, and that, for more than half a century, zealous investigators had been devoting themselves to the experimental study of that possibility. Prominent among this group of experimenters may be mentioned Koelreauter, John Hunter, Herbert Knight, Gartner, Jordan. Naudin, Godron, Lecoq, Wichura--men whose names are familiar to every reader of Animals and Plants unders Domestication.
William Bateson
If going beyond the experiences of past seers and sages is so shocking, each new seer or sage in turn has done that shocking thing'Buddha, Shankara, Chaitanya, etc. all did that wicked act.... Truly, this shocked reverence for the past is a wonderful and fearful thing? After all, the Divine is infinite and the unrolling of the Truth may be an infinite process or at least, if not quite so much, yet with some room for new discovery and new statement, even perhaps new achievement, not a thing in a nutshell cracked and its contents exhausted once for all by the first seer or sage, while the others must religiously crack the same nutshell all over again, each tremblingly fearful not to give the lie to the 'past' seers and sages.

Three and a half million years separate the individual who left these footprints in the sands of Africa from the one who left them on the moon. A mere blink in the eye of evolution. Using his burgeoning intelligence, this most successful of all mammals has exploited the environment to produce food for an ever-increasing population. In spite of disasters when civilisations have over-reached themselves, that process has continued, indeed accelerated, even today. Now mankind is looking for food, not just on this planet but on others. Perhaps the time has now come to put that process into reverse. Instead of controlling the environment for the benefit of the population, perhaps it's time we control the population to allow the survival of the environment.
