A leading example is food supply – an area where technology has continually produced ever-more highly processed and genetically refined food that scientists are only beginning to assess. What is known so far is that childhood obesity has become an epidemic in many countries, with an alarming rise in rates of type 2 diabetes and coronary disease implying a significant negative impact on life expectancy in future generations.
一个显著的例子是食品供给。在这一领域，科技在持续生产着日益复杂的转基因食品，而科学家对这些食品的评估才刚刚开始。如今，我们知道儿童肥胖已是很多国家的一个普遍问题，2型糖尿病和冠心病的高发也是一个令人警惕的信号，会对子孙后代的预期寿命带来巨大的消极影响。
