Wiley, New York. METHODOLOGY RESULTS AND DISCUSSION FUTURE PROSPECTS REFERENCES ... Table 1 Guayule ( Parthenium argentatum Gray) is a promising alternative to rubber tree ( Hevea brasiliensis Muel. Arg.) for production of natural rubber in semiarid regions of the world. For the United States, which is totally dependent on foreign sources of natural rubber, developing guayule as a commercial crop should be a high priority. A domestic source of natural rubber is vital to our national defense and helps balance the budget by reducing the one billion dollars spent annually for the imports of Hevea rubber from southeast Asia. Salt-tolerant guayule cultivars are needed for economic production of rubber on marginal lands and in areas with low quality saline water. The available guayule germplasm which is being used to develop new guayule cultivars are 2 n = 36, 54, or 72 (Bergner 1944, 1946; Stebbins and Kodani 1944). Plants with 2

Extractions: on the edge of the Malthusian precipice? A briefing document prepared for the Royal Society and Association of British Science Writers by Mike Holderness On 4 and 5 December 1996, the Royal Society held a scientific meeting entitled "Land Resources: on the edge of the Malthusian precipice?" This document was prepared afterwards to summarize key issues raised by the speakers and to provide a list of helpful contacts for future reference. March 1997 There are two ways of looking at the Malthusian precipice: as an edge over which we can rush like the Gadarene Swine into the abyss; or as the heights which we are climbing, rather successfully so far. From the introduction by the Chair How hungry will our children be? How many people will there be in the world by, say, 2050? How much food will they be able to grow, for how much longer after that and at what cost? In 1798 the English clergyman Thomas Malthus published his Essay on the Principle of Population . He noted that population rises geometrically. That is, if 10 people occupy a tiny island and each generation has twice as many members as the last, succeeding generations will have 20, 40, 80, 160, 320... members. He suggested that food production can only rise arithmetically: each generation may have the capacity to feed 100, 120, 140, 160, 180, 200... people. The fifth generation of our islanders reach the "Malthusian Precipice". "The power of population is so superior to the power in the earth to produce subsistence for man," Malthus concluded, "that premature death must in some shape or other visit the human race."
