尽管这些说法多数未被科学 证实，但是由于大量文章支持这一观点，使得普通群众难辨真伪。 因此那些认为只食用绿色食品就能防治疾病或增进健康的观点便广为人知，并导致一些不科学的做法和****惯。 公众几乎每天都被"抗衰老"食品、新型维生素以及其它具有神奇功效的食物广告所包围。 声称天然维生素优于人造维生素，受精蛋比未受精蛋的营养价值更高，未经薰蒸消毒处理的谷 物比经过处理的好等等诸如此类的报道屡见不鲜，但没有一篇是经过证实的。

These two episodes suggest that the third great change, the present rapid growth, which began in the West between 250 and 350 years ago, may also slow down when, or if, technology begins to yield fewer innovations.
Of course, the current knowledge revolution may continue without foreseeable end. Either way - contrary to popular belief in constant geometric growth - population can be expected in the long run to adjust to pro
