冰川，或稱冰河是指大量冰块堆積形成如同河川般的地理景觀。冰川是地球上最大的淡水資源，也是地球上繼海洋以後最大的天然水庫，約佔地球上淡水總量的69％。约有24亿人口是生活在发源自喜马拉雅山脉的河谷地区中，在旱季时冰川消融的淡水孕育了这些人们赖以生存的河流。青藏高原的冰川正以每年7%的速度消退着，例如本活动的折返点：在珠峰山脚下的绒布冰川，在过去30年里就退缩了270米。可以说冰川地区是对全球暖化反应最敏感的地区之一。

About Glaciers
A glacier is a perennial mass of ice which moves over land. Glacier ice is the largest reservoir of fresh water on Earth, and is second only to oceans as the largest reservoir of total water, which hold about 69% of the fresh water on Earth. About 2.4 billion people lives in rivers valleys originate from Himalayas. Their livelihood depends on the melting of fresh water of Himalayas glaciers during dry season. Glaciers in Tibet area is melting at annual rate of 7%, like the turning point of our trip: Rongbuk glacier retreated 270M in the last 30 years. Glaciers area is one of the most vulnerable areas under tread of global warming.

自行车
或任何人力车，人们可以用自己的力量踩踏前进。比起走路，自行车速度快也较不费力。不用像汽车那样要加汽油，也不会排放任何的废气。中国人民正骄傲的说：2009年，在中国卖的汽车，超过一千万辆，比美国还多！在中国大城市人们骑满自行车的景象，已经被人们记上落后的标签，深深的埋藏在记忆中。这是一个不可逆转的事实，但我们总觉得骑自行车其实也是一种很不错的前进方式，不需要总是挤在前面，跟着自己的意念与力量前进吧！
Bicycle
Or any other form of human power vehicles, moving forward with ones own strength. It is faster and less tiring than walking and unlike driving a car; you do not burn any fossil fuel and do not give out any carbon dioxides besides your own breath. People of China are proudly saying: In 2009, more cars are sold in China then in America, more then 10 millions cars! They want to deeply bury the underdeveloped images of cyclist packing their cities streets. That scene is long gone, but we still believe bicycle is a good way of traveling which you do not need to rush ahead, just moving forward by follows your leg and mind.
