哥伦布前的美洲

National Geographic embarks on an expedition into the mysterious world of ancient American history to shed a different light on the history of the Americas.


　　History books traditionally depict the pre-Columbus Americas as a pristine wilderness where small native villages lived in harmony with nature. But scientific evidence tells a very different story: When Columbus stepped ashore in 1492, millions of people were already living there. America wasn't exactly a "New World," but a very old one whose inhabitants had built a vast infrastructure of cities, orchards, canals and causeways. But after Columbus set foot in the Americas, an endless wave of explorers, conquistadors and settlers arrived, and with each of their ships came a Noah's Ark of plants, animals—and disease. In the first 100 years of contact, entire civilizations were wiped out and the landscape was changed forever.

这样的片如果信息量换成书也就100页吧，但100页不一定100分钟能看完，这问题应该计算一下哪个划算

哥伦比亚大交换，将美洲和非洲的交集，以物种的角度来看，微观视角很有启发。

划时代的大交换。<第二集不是哥伦布后的美洲吗>

Summer, 1492. 喜欢旁白的声音。

美国做的为啥解说却是British accent？？？

美洲的文明之所以脆弱，是因为太过特化。在每一个环节上几乎都没有可替代的资源。于是这种平衡的任何一环被破坏，灭亡也就不远

很喜欢！CCTV9正在播放1HestiaTäter2012-05-03德版为1492 Der Kolumbus Effekt...用了很多zdf自有版权的die Deutschen和Europa im Mittelalter的画面....估计应该是和NG合拍的片子...说起来不到五百年的时间北美印第安人骑马..欧洲人吃土豆就已经被视为一种常态了（2012.10.23）

说过千万遍的东西。。。。不过就介绍来说不错

在原始的美洲大陆上, 一个废弃的城池, 诠释了人类用最原始的工具, 对自然环境造成的极大破坏----他们砍光了周边所有的树----一个令人震惊的片断. 由此对人类的行为有了深一层的认识.

很长知识！ 都是常识！ 就是没这么生动地听过~

从前的这片土地是这样的…其实挺难想象，有种亲切感。
