Few places in the United States better illustrate the unforeseen consequences of population growth than the lower valley of the Hudson River, which runs south from Albany to New York City. The river is wide and placid in appearance, and its banks sparkle with towns that were young when the nation was young. To the west rise the Catskills, blue at sunset and blanketed by trees. Interstate 87 makes a ribbon between the water and the mountains. A while ago I spent some time driving on that road, and down long miles of its length the forest stretched out so far and so dark and so empty that I imagined I was looking at the America of a hundred years ago, before there were millions of people like me around. How wonderful, I thought, that so close to Manhattan is a huge piece of real estate that we never trashed.

好好学习，天天向上

一些地方在美国更好地说明无法预见的后果的人口增长比哈德逊河下游，是从奥尔巴尼向南到纽约市。河宽和文静的外表，和银行闪耀城镇，是年轻的国家的年轻的时候。在西方兴起的卡茨基尔，蓝色的日落和银装素裹。87号州际公路使水和山之间的丝带。不久前，我花了一些时间在道路行驶，下长英里长的森林伸到目前为止，如此的黑暗和空虚的，我认为我是在看着一百年前的美国，之前曾有人和我一样在数以百万计的人。好，我想，如此接近曼哈顿是一个巨大的房地产的作品，我们从不丢弃。
