River clean-ups are organized efforts to remove trash and debris from rivers and their banks. Volunteers, often from local communities, gather to collect litter, which can include plastic bottles, cans, and other waste. These activities help improve water quality, protect wildlife, and enhance the natural beauty of the area. During a river clean-up, participants may use tools like gloves, trash bags, and nets to gather waste. Many organizations, such as environmental groups and community service clubs, coordinate these events to raise awareness about pollution and promote environmental stewardship among local residents.
