The document summarizes a clean and green contest planned by children at GPS Moosabowli School. The children felt that many cities are polluted and they wanted to bring change by keeping their school, homes, and surrounding areas clean to live happily and avoid diseases. They shared their idea with community leaders and residents who supported implementing the clean and green program. The children then worked together to start the program by discussing its advantages and sharing it with other students and teachers while cleaning the school grounds, plants, and removing trash from surrounding places.
