In parts of the Eastern United States and Western Europe, rain and snow now fall as dilute solutions of sulfuric and nitric acids. A by-product of the burning of fossil fuels in power plants, the problem of "acid rain" is expected to worsen as industrialized countries become more dependent on coal, say ecologists Likens, Wright, Galloway,...

Three to 5 percent of total US. energy output (e.g., equivalent to the energy produced the nation's hydroelectric plants) is consumed pre- paring food at home. Much of that energy could be saved if Americans changed their cooking and eating habits, write nutritionists Rawitscher and Mayer.

Inefficient forest management has spurred government predictions of a "timber famine" the year 2000 in the Pacific Northwest, source of one-fourth of the annual U.S. timber harvest.
No such famine need occur, argues Hyde, a research associate at Resources for the Future. Annual harvests in the Northwest range from 24 million to 26 million "cunits" (one cunit...
and large, scenic vistas-rocky outcrops, steep slopes, alpine meadows-rarely include rich timber country. Moreover, soil erosion caused tree-felling, hauling logs, and road- building is more likely in these areas; there is far less damage where the terrain is flatter-and lumbering is most profitable.
Hyde concedes that environmentalists object to some of the foresting methods he endorses~clearcutting (the most efficient form of tree-harvesting) and shorter intervals between harvests (30 to 50 years...
"The Color Film Crisis" Paul C. Spehr,

tion Service, P.O. Box 966, Farmingdale,

During the 1950s, Hollywood switched from Technicolor to Eastman Color (still in use today). The result has been new films that fade within a few years to an ugly purple and negatives that will be worthless within a lifetime.
Many of the films-e.g., The Wizard ofOz (1939),An American in Paris (1951)-printed by the old Technicolor method retain their...
contrast, are durable but as yet can only be shown on television screens. One preservation technique under study involves the use of laser-beam holograms (re- cordings of the patterns of light waves).
Many great films of the last 25 years will likely fade into oblivion before the means to save them are perfected, Spehr concludes-all because movie makers failed to reckon on the future profits to be made from the public's abiding interest in their creations.

Ethnic consciousness has been on the rise in the West-for example, among France's Bretons and Canada's Quebeqois. But separatist movements have not always cropped up as a result. Gourevitch, a McGill University political scientist, surveyed eight countries to find out why.
When both political leadership and key industries are centralized in...

Seeing the Soviet Union's massive economic support for Castro's Cuba, Salvador Allende, head of Chile's short-lived Marxist government, ex- pected Moscow to underwrite his socialist program. He was disap- pointed; the Russians did not provide the needed cash. The Kremlin's desire to preserve detente with...
1972, for example, 33 percent of all state-owned buses were out of service due to parts shortages.) Anticipated revenue from the nationalized copper industry was down $500 million in 1971-72 because the worldwide price of copper dropped from 64c a pound in 1970 to 48c a pound in 1972. Yet assistance from the presum- ably sympathetic Soviets amounted to no more than $340 million from 1971 to 1973.
Why did Moscow fail to bail out Allende? The Soviets do not have unlimited means, say the authors;...
