1 At first,the grains of rice that Ingo Potrykus held in his fmgers did not seem at all special,but inside,these grains were not white,as ordinary rice is,but a very pale yellow—thanks to beta-carotene,a building block for vitamin A.
2 Potrykus was elated.For more than a decade he had dreamed of creating a golden rice that could improve the lives of millions of the poorest people in the world,strengthening their eyesight and their resistance to disease.
24 The popular belief that agricultural biotechnology is bad for the environment puzzles the Rockefeller Foundation’s Conway.He sees genetic engineering as all important tool for achieving a “doubly green revolution.” If technology can increase plant’s natural defenses against weeds and viruses,if it can make crops grow using only small amounts of chemical fertilizers or in drought—ridden land,then what’s wrong with it?
Of course,there will be fewer children to feed and educate.But most experts agree that while aging societies may be able to divert some resources that now go to the young,the increasing cost of supporting the elderly is almost certain to consume these savings many times over.
Throughout the developed world,total public spending per old person is two to three times as great as public spending per child.And in the future,that gap will probably widen.The elderly consume far more health care resources than do children,and new technologies to extend life are bound to escalate health care costs.

1、起初的时候,Ingo Potrykus教授（著名植物学教授）手中的谷类看起来没什么特殊的,这些谷类和普通谷类一样,都不是很白,而是发浅黄色,这是β-胡萝卜素的原因,它阻止了维生素A营养的流失.
2、Potrykus教授十分得意,他不仅仅是创造了一个大米/谷物的黄金时代,还可以改善世界上数以百万计的贫困人口的生活,同时增强了他们视力和免疫力.
24、人们认为,农业生物技术（转基因、农药、化肥等）对环境是有害的,这让洛克菲勒基金会的Conway十分为难.因为他把基因工程视为能够达到“双重绿色革命”最重要的手段.如果农业生物技术能够提高作物的自然抵抗力,从而降低野草和病菌对作物的侵害；或者只需要少量的化肥就能让粮食的产量大幅提高,并提高作物的抗旱能力,那么这又有什么错呢?
当然,在未来需要抚养和教育的孩子的人口数量会有所减少.但大多数专家都相信,老年人们如果把注意力从关注年轻人们身上挪开一点,就会发现这样一个事实：老年人日益增长的资源消耗,几乎是现今社会资源存储量的几倍.
在现如今发达的社会里,一个老人的公共开支是一个孩子两到三倍.在未来这个缺口还会进一步增大.老年人和孩子在健康方面的支出差距越大,能够延长寿命和维持健康的技术就越势在必行.
