Swapping events are organized gatherings where participants exchange items, such as clothes, books, or toys. These events promote sustainability by encouraging the reuse of goods, reducing waste, and fostering a sense of community. Participants bring items they no longer need and can select new items brought by others, creating a fun and interactive experience. Typically, swapping events are held in community centers, schools, or local parks. They may have specific rules, such as limits on the number of items each person can bring or guidelines on the types of items accepted. Overall, swapping events provide an eco-friendly alternative to traditional shopping.
