解析
根据关键词fish定位至最后一段Marketscannotalwayskeeptheenvironmenthealthy.Ifnooneownstheresourceconcerned,noonehasaninterestinconservingitorfosteringit:fishisthebestexampleofthis.可知作者只是以“鱼”为例说明“如果人们不拥有关心的资源,人们对保护或者养殖也不感兴趣,市场是无法一直保持环境的健康。”题干问:为什么鱼类资源在减少?选项A:因为没有找到新替代品;选项B:因为水污染引起的严重问题,无中生有;选项C:因为鱼类资源不被任何实体拥有;选项D:因为捕鱼方式不可持续,无中生有。结合段落内容可知正确答案是选项C。
