2015-would put the total population at 4.90 billion in 2000, an increase of only 2.1 percent, and a modest price to pay for a much healthier population.
At this point in the demographic transition, the biggest population changes are likely to come from drops in the fertility rate. The UN projections assume an annual decline of .07; a 50 percent greater de- cline would mean an 18.8 percent decrease in the projected population 2100. In fact, the most effective techniques for extending life expec-...
repeating the swing several times and gradually developing a return stroke that minimized drag, they could leap even further. Once natural selection refined their wings and increased their endurance, they left the ground behind.

The Last hk "Zoos: Endangered Species' Last Hope?" Joseph Wallace, in Museum (May-June 1982), Museum Circulation Services, P.O. Box 1300, Bergenfield, N.J. 07621.
Nowadays, zoos must be more than just showcases for exotic animals. As one zoo administrator puts it, "Zoos must...
the end of this century an estimated one million species of plants and animals will face extinction. The expense of main- taining even one animal in captivity is high, and often an entire herd is needed to ensure successful breeding. Better communication among zoos has helped spread the responsibility. But zoo experts now face the weighty task of choosing which of the earth's dwindling species will be saved and which will disappear.

Since the accident at Three Mile Island in 1979, Americans have been more worried than ever about the safety of nuclear power plants. Co- hen, a physicist at the University of Pittsburgh, belittles many of the alleged risks.

Sigmund Freud looked at the writings and paintings of Leonardo da Vinci (1452-1519) and found evidence of a neurotic obsessional per- sonality-a man whose repressed love for his mother prevented normal heterosexual development. Aaron, an educational psychologist, and Clouse, a historian, both at Indiana State University, see instead the effects...
"Art Versus Collectibles" Edward C. Banfield, in Harper's (August 1982), P.O. Box 2620, Boulder, Colo. 80321.
When former Vice-president Nelson Rockefeller began selling high- quality reproductions of his private art collection, the art world was shocked. Hilton Kramer, former art critic of the New York Times, lamented "a new era of hype and shamelessness." Banfield, a Harvard government professor, argues that Rockefeller had the right idea.

his assistants and then printed others. Sculptors today routinely make models in clay, wax, or plastic to be cast at foundries, often in sizes different from the original.
Two groups are responsible for the resistance to creating and show- ing high-quality reproductions, says Banfield. Art historians teach the public to value art "relics" as part of history, rather than as "something to be responded to aesthetically." And private art collectors make pur- chases for the same...

Public art museums may be strapped for cash today, but corporate art buying is on the rise. Chase Manhattan Bank's collection, begun in 1959, is worth $7.5 million, and its art purchaser is looking for more- which is good news for contemporary artists, writes Brooks, assistant managing editor of The ARTnewsletter.
Since the mid-1970s, corporate buyers have been aggressively seek- ing art they can display where...

On March 20, 1980, a handful of Cubans sought asylum at the Peruvian embassy in Havana. Before the dust had settled, 125,266 Cubans had immigrated to the United States. Much has been made of their impact on this country. What does it mean for Cuba?
