Before 2025.

会影响近二十亿人
Yet water is still abundant in unspoiled regions of the planet.

然而地球上一些处女地仍然水量丰沛
The wetlands.

湿地
These wetlands are crucial to all life on earth.

这些湿地对地球上的生命至关重要
They represent six percent of the planet.

它们占据地球表面积的6％
Marshes are sponges that regulate the flow of water.

沼泽是调节水流的海绵
They absorb it in the wet season...

雨季时吸水
And release it in the dry season.

旱季时排水
The water runs off the mountain peaks,

水从山峰上奔流直下
Carrying with it the seeds of the regions it flows through.

携带着流过区域的种子
This process gives birth to unique landscapes,

这一过程造就了独特的风景
Where the diversity of species is unequaled in its richness.

那里的物种无比丰富
