摘要：Assuring food security for the next 25 years requires meeting a number of political, social,economic, and technical challenges. One of these is the successful use of new biotechnologies inagriculture. Research in recombinant genetics and biotechnology aims to develop plant varietiesthat provide reliable high yields at the same or lower costs by breeding in qualities such asresistance to disease, pests, and stress factors such as aridity. Realization of these goals could leadto tremendous gains in food production. However, biotechnology is now evoking the sameobjections that have been raised against the Green Revolution--that its benefits are distributedinequitably in favor of the large, rich farmers and that it is potentially environmentally destructive.
