未来城市：垂直农场

到2050年，全球将有七成的人居住在都市，城市必须供养70亿人口。如果用传统的土壤耕作，还需要增加一整个巴西的耕作面积，才有可能养得活这么多的人，但是高楼林立的城市里，哪里生得出这么多土地呢？如果城市能够盖出摩天大楼，有可能盖起摩天农场吗？为了解决城市粮食供应的问题，垂直农场应运而生。 城市垂直农场把水平的农场，改造成种满植物的摩天大楼，用营养液代替土壤，用LED灯取代阳光，这些彷佛科幻小说的情节，在各领域专家的努力下，正一步步成真。垂直农法在密闭的空间种植农作物，压缩了空间，让效益极大化，除了节约土地，也节约用水量，用水仅是传统土壤种植的十分之一。可以楼上种菜，楼下卖菜的垂直农场，也大大缩短了食物里程，减少食物长途运送的资源浪费。 垂直农场发想者的本意，是解决全人类的问题，然而这种耕作方法现阶段仍有个无法克服的致命瓶颈，就是生产成本太高，目前只能为少数阶级服务，奢侈品是无法养活全世界的。全球人口最多的城市，有四分之三分布在亚洲，这些亚洲的大都市，无不全力支持垂直农场的发展，因为比起其它地方，他们分秒必争。

巨石阵行动：被埋藏的秘密 第一季

Stonehenge is an icon of prehistoric British culture, an enigma that has seduced archaeologists and tourists for centuries. Why is it here? What is its significance? And which forces inspired its creators? Now a group of international archaeologists led by the University of Birmingham and the Ludwig Boltzman Institute in Vienna believe that a new state-of-the-art approach is the key to unlocking Stonehenge&#39s secrets. For four years the team have surveyed and mapped every monument, both visible and invisible, across ten square kilometres of the sacred landscape to create the most complete digital picture of Stonehenge and the surrounding area over millennia. Known monuments have yielded more data than ever before, revealing hidden structures within, and new finds are revolutionising the very timeline of Stonehenge. Operation Stonehenge takes the viewer on a prehistoric journey from 8000BC to 2500BC as the scientists uncover the very origins of Stonehenge, learning why this landscape is sacred, preserved and has been revered by following generations. Evidence of war and conflict, as well as the cultivation of ideas and industry, is explored to reveal complex communities with international trade links as far-reaching as Spain and central Europe. Using CGI to reveal the monuments hidden beneath Stonehenge and featuring factually sourced dramatic reconstructions, the stories of the buildings and the people that occupied this sacred landscape over four millennia ago are revealed in comprehensive detail.
