Societies should try to save every plant and animal species, regardless of the expense to humans in effort, time, and financial well-being.
a) 植物与动物对与生态环境的保护,十分重要。植物的光合作用提供了氧气与动物的食物提供了栖息地,动物为人类和其他物种提供了生存的必需。比如,磷虾krill为南极动物提供了食物,如果磷虾灭绝南极生物都会面临灭绝。热带雨林被破坏,影响地球的气候,影响人类的生存
b) 社会的资源是有限的,不能过分的进行保守的保护,人类也要生存。比如家具需要木材,砍伐树木。人类需要食物,捕捞海洋鱼类。他社会问题同样需要投入人力财力,比如失业,贫困,自然灾害
c) 更好的办法是开发利用与保护的平衡,既在可能的范围内保护动植物,也保障了人类自身的需要。比如可以一边砍伐树木一边植树造林。可以通过科学方法进行人工培养,不破坏野生种群,比如磷虾
2. 社会进步:
The problems of modern society have led many people to complain: We live in terrible times. Yet, given the choice, no one today would prefer to live in any other time.
a) 随着现代社会发展,出现了许多新的,复杂的社会问题:失业,日益恶化的环境,儿童犯罪等等
b) 不可否认,社会文明程度发展了,科学技术水平发展了,人们的生活水平提高了。比如移动电话给人们的通讯带来极大的便利,网络的发展使得我们可以获得更多有价值的信息
c) 解决了许多过去存在的社会问题,比如瘟疫,妇女的选举权
What we call progress is a matter of exchanging one problem for another.
Any decision-whether made by government, by a corporation, or by an individual person-must take into account future conditions more than present conditions.
People are mistaken when they assume that the problems they confront are more complex and challenging than the problems faced by their predecessors. This illusion is eventually dispelled with increased knowledge and experience.
