A girl at a kindergarten in Liaocheng, East China's Shandong province, holds up a drawing which shows how to avoid wasting water, on March 22, as part of activities marking World Water Day, which has been held every year since 1993. This year's theme is "Water and Energy", which the UN says are "closely interlinked and interdependent." [Photo by Zhang Zhenxiang/Asianewsphoto] |
