问题     In the debate over genetically-altered foods, proponents Nike Senator Richard Lugar argued that such products will be essential (31) we are to feed the world.
    (32) this claim rests on two persistent misconceptions about hunger. First, (33) people are hungry because of high population density, (34) second, that genetic engineering is the best or only way to meet our future needs.
    In (35), there is no relationship between the prevalence of hunger in a given country and its population. (36) every densely populated and hungry nation like Bangladesh, there is sparsely populated and hungry nation like Brazil.
    The world today produces more food per (37) than ever before. Enough is available to provide 2 kilograms to every person every day. The real problems, (38), are poverty and inequality. Too many people are too poor (39) buy the food that is available (40) lack land on which to grow it (41). As a matter of fact, some researchers have shown that (42) of the genetically-engineered seeds significantly increases the (43) of crops.
    Far from (44) a solution to the world’s hunger problem, the rapid introduction of genetically-engineered crops (45) actually threaten agriculture and food security.
    (46), widespread adoption of herbicide-resistant seeds may (47) to greater use of chemicals (48) kill weeds. And biological pollution from genetically-engineered organisms may be another problem.
    A true solution (49) the problem of hunger depends on attacking poverty and inequality among both producers and consumers of food. (50) food system increasingly dependent on genetically altered seeds takes us in the wrong direction.
