世界人口不断膨胀,自然资源和环境又日益受到破坏,要为亿亿万万的人提供足够食物,真是谈何容易。基思·施奈德(Keith Schneider)在本文中简介了美国农用生物技术近年的发展。这种技术是以人工方法把不同的动、植物,微生物的基因加以混合或拼接,以改变它们的性状,培育出抗害虫、抗毒菌的植物及新品种的牲畜。但这种技术是否真正可以减少污染环境而又可以解决人类的食物问题,尚有待进一步研究和探索。 As the world’s population continues to expand and the natural resources and environment are increasingly undermined, it is really much easier to provide enough food for billions of people. In this paper, Keith Schneider introduces the recent developments in agricultural biotechnology in the United States. This technique involves artificially mixing or splicing different genes of animals, plants and microorganisms to change their traits and to produce plants that resist pests, anti-toxin bacteria and new breeds of livestock. However, whether this technology can really reduce the pollution of the environment and solve the problem of human food remains to be further studied and explored.
