Duck Lily lived on a small lake surrounded by beautiful flowers and trees. But one day the fish and plants began to disappear from the lake, and the water began to lose its purity. Lily noticed with alarm how her home was gradually changing and wanted to find out what was happening.
She went to the shore of the lake, where she met a frog who was also sighing sadly, looking at the dying lake. The frog told Lily that the river feeding the lake was polluted, and life in the lake was gradually fading. This news broke her heart, but Lily decided to go to the river to find the source of the trouble.
When Lily reached the river, she was met with a terrible sight: the water was muddy, full of garbage and dark shadows that filled the depth of the river. Lily shook her head sadly, unable to believe that her native places had become so gloomy and dangerous.
Lily flew further along the river and saw factories and plants that were dumping their waste into the water. Lily's heart was torn with grief, for she realized that she could do nothing to stop this evil.
On her way back to the lake, Lily felt that she was running out of strength. She landed on the shore, feeling that her native place was lost forever. The pain of loss and helplessness squeezed her heart, and she cried bitterly, looking at the dark waters of her lake.
In the evening, when the silence surrounded the lake, Lily fell asleep on the shore, dreaming of clean waters and green meadows. Sleep took her to a world where the water was clear and life was carefree. In this dream, she stayed forever.
