Pimentel, a professor of insect ecology and agricultural sciences at Cornell, is one of three visiting scholars in a series entitled "Natural Resources Management: Challenges and Promises for the Fut ure." The series is spon sored by UNL's Depart ment of Forestry , Fisheries and Wildlife and funded by a grant from the Layman Fund. CORNHUSKER J SALE 30 OFF 4 1 speaks en In a slide presentation paralleling natural resources - energy, land, water and humans and world food production, Pimentel stressed various forms of energy use in our current food system. He added that humans have both a positive and negative impact on the relation ship, because we consume other resources but also contribute to natural resource development. There is not necessarily a shortage of the world's natural resources, he said, but rather an overabund ance of people. Pimentel traced the liistory of U.S. population and energy consumption. Currently, the United States makes up 6 percent of the world's population but burns 33 percent of Make some Fast and save 10-30 on ail shoes in stock! mpc vaqe V- U-MKl .M V.l. 8 i j 2 i i 2 C3 C,3 t3 3 C3 V.V 3 i i I ) i i ) i t 9 i CI C CJ c ' CJ C CJ CO oa 00 os Co 5 J J !

Many less-developed count ries rely on biomass energy - usually in the form of wood - for their primary source of fuel, lie said. However, Pimentel indi cated that world forests are shrinking. Trees arc being cut for fuel; forests are being eliminated for use as cropland. He went on to discuss the availability of arable land. In 1650, there were four acres of usable farm land per person. Iiy 1975, that figure had reportedly decreased to nine-tenths of an acre per person, he said, based on an esti mated world population of four billion.

Most farmable land in the world is already in production, Pimentel said, "even though some of it shouldn't be." "Hie less land you have available, the more intensely you have to manage it," he said. Water erosion also can present a problem in food production, he said, since soil formation is such a slow process. Under agri cultural conditions, it takes 200 to 300 years for 1 inch of topsoil to form. Pimentel said methods to prevent erosion, such as contour planting and terracing, can be effective, but have not seen wide spread implementation. On a woild basis, almost 50 percent of the potential world food output is lost to pests like insects and rodents. He reported that 17 percent of all energy used in the United States is for food production. If all current petroleum reserves were used for food product ion, they would last about 13 more years, Pimentel predicts. Pimentel said he "anti cipates severe crises" in future food production. "It will get worse before it gets better," he said. u i i - Saturday n - Wed I TENNIS BALLS $217 A Can!
