可持续总结(Summiting sustainably)

为了纪念国际山地日，请尽可能多地呼吸那甜美、清新的山地空气。看到那阴影从喜马拉雅山崎岖的天际线延伸过去了吗？这是由珠穆朗玛峰铸造的，珠穆朗玛峰是所有山峰中最高的，海拔29032英尺。

In honour of International Mountain Day, breathe as much of that sweet, crisp mountain air as you can. See that shadow stretching past the Himalayas' craggy skyline? That's cast by Mount Everest, the tallest peak of them all, rising to 29,032 feet above sea level.
