简介:

  Ancient Worlds is about people and places, politics and economics, art and war, trade and technology, but above all it’s the story of the painful birth and difficult growth of a radical idea first tried and tested some six thousand years ago, and which we are still struggling with today; civilisation. Civilisation has not come easily; it’s something we’ve had to fight hard to achieve, and even harder to maintain, and the greatest threats to it have come from our own talents for destruction. But when we’ve managed to get it right, the benefits have been enormous.
  When we talk about the ancient world we tend to think of rare and exotic artefacts or the monumental remains of epic architecture; but these are just the empty shells that got left behind when the tide of history turned! The living creatures, the civilisations, that once inhabited these shells were rarely if ever static or stately; they were dynamic, chaotic, and always threatening to spin out of control, because civilisation is based on an improbable idea; that strangers can live and work together in dense urban settings, forging new allegiances that replace the natural ties of family, clan or tribe. It’s an idea we’re still coming to terms with today, but one of the best ways to understand the challenges that are involved is to look at how our ancestors tackled them the first time around.
  From ancient Iraq to Imperial Rome, Ancient Worlds examines how our ancestors struggled with the levers of religion and politics, art and culture, war and diplomacy, technology and trade in order to keep the complex machinery of their civilisations turning over. Their insights and blind-spots, their breakthroughs and dead ends, their triumphs and disasters are the milestones on the long and winding road that leads directly from their ancient to our modern world.

简介:

  大峡谷Grand Canyan位于美国亚利桑那州西北部科罗拉多河中游、科罗拉多高原的西南部,是地球上最为壮丽的景色之一,由深邃的山谷所夹峙,分成南壁与北壁两部分。南壁因交通方便,也有旅社等设施,而且在冬季雪期,仍能欣赏天然奇景,因而成为观光大峡谷的中心。
  自冰河时代开始,直到今天,在无数世纪间,科罗拉多河不断地侵蚀大地,终致形成这一大峡谷,长度达347公里。该峡谷起于马布尔峡谷,终端为格兰德瓦什崖,全长446公里,是世界上最长的峡谷之一。峡谷顶宽6至28公里,最深处1800米。从谷顶到谷底需3至4小时。谷底两岸的宽者小于1公里,窄处仅120米。两侧的谷壁呈阶梯状。谷底水面不足1000米宽,夏季冰雪融水下注,水深增至18米。山石多为红色。从谷底至顶部沿壁露出从前寒武纪到新生代各期的系列岩系,水平层次清晰,岩层色调各异,并含有各地质时期代表性的生物化石,故有“活的地质史教科书”之称。
  而今天,由于我们人类的过度开发,我们的地球濒临干涸,因为这颗星球上很多纯净的水资源正在以我们无法想像的速度大肆流逝。科罗拉多河,这条美国最具代表性的河流,大峡谷的骄傲杰作,世界首选的旅游胜地,就让它的故事来告诉我们如何拯救这个危在旦夕的星球,如何应对世界水短缺吧。
