单选题One day a businessman was going to another town to sell his goods (货物). He decided to take ten servants(仆人) with him. They would carry his goods and also some food to eat on the way. He said to one of the servants, "You are the smallest and the shortest one. You may carry the lightest load (担子). "The servant thanked him but took the biggest load. This was the bread to eat on the way.
The man said, "You"re foolish. That is the heaviest load." But the servant took up the load happily, and so they set off. After four hours they stopped for a rest. They all ate some of the bread. Then there was less bread for the servant to carry. Every time they ate some bread, the load became smaller and lighter. At the end of the trip, the servant had nothing to carry, and all the other servants still had a lot of things to carry.

单选题破坏自然资源和污染食物的事不断发生，这主要是因为对那些不顾后果、肆意破坏环境的人难以追究法律责任。通过立法、经济刺激和善意劝说等防止污染的努力遇到诉讼、个人和企业的否认及旷日持久的拖延——不仅在接受责任方面，更重要的是在有关其处理方面。好像只有当政府决定采取税收优惠或者牺牲生产时，他们才会主动改变。保护人类的伟大宝库是一项最重要的责任，企业和我们对此的共识何在?如果能有环境卫生的专业人员到第一线来领导解决环境问题的时刻，那么这个时刻就应该是现在。
人们正在要求我们，实际上，公众正在命令我们采取积极行动。作为环保专业人员，我们的责任是要改变现状。是的，生态学家、环境保护活动家和资源保护者起着沟通刺激人们思想、促进行为变化的作用。然而，正是我们这些人领取了报酬来决定发展、改善和执行环境保护标准，所以我建议，我们必须负起领导责任。我们必须认识到环境健康问题并不仅仅局限于城市以内、县界、州界甚至联邦边界。在方法上我们不能再目光狭隘了，我们必须从各个方面看待问题，以做出客观的决策。我们必须清楚地表达我们的观点，以防媒体曲解和公众迷惑。
我认为，目前我们有三方面任务。第一，我们必须继续主张高质量的生活，这一点人们自己可以做到。第二，我们必须调查，并且搞清楚环境和健康之间的关系。第三，我们必须以公民能够理解的形式来传播技术信息。如果我们能在这几年之内完成这三个目标，也许我们最终能使环境停止恶化，而不仅仅是控制它。那时，我们就能把治理污染的钱真正用于预防，而不是用于补救。
