塑料袋在水体岸边污染环境。人类垃圾危及生态系统。

ide shoreline is framed by tall green reeds and calm water rippling gently in the background. Near the edge of the water, a discarded plastic bag lies trapped among the plants, highlighting pollution in the natural environment. Trees and distant buildings can be seen across the lake under bright daylight, creating a contrast between the peaceful scenery and the visible human waste.
