变灰的

World dominated by humans on Earth into the animal kingdom, before the stink to high heaven of the Wu Shuigou into a clear bottomed creek, Gosling, ducklings trouble playing catch in the river; barren hills into a dense forest , birds mischievously, Trees towering; Gray-headed gray face, the sky becomes blue, such as washing; barren land into a cattle and sheep compete for grasslands ...... the Earth has undergone enormous changes.

地球由人类统治的世界变成了动物的王国，以前臭气熏天的污水沟变成了清澈见底的小河，小鹅、小鸭在河中追闹嬉戏；光秃秃的荒山变成了茂密的森林，百鸟欢畅，千树峥嵘；灰头灰脸的天空变得湛蓝如洗；寸草不生的土地变成了牛羊争抢的草原……地球发生了翻天覆地的变化。
