Reusable bags are eco-friendly alternatives to single-use plastic bags. Made from materials like cotton, jute, or recycled plastics, they are designed to be used multiple times, reducing waste and environmental impact. Many stores encourage their use by offering discounts or incentives for customers who bring their own bags. These bags come in various sizes and styles, making them suitable for grocery shopping, carrying books, or even going to the beach. By choosing reusable bags, individuals can contribute to sustainability efforts and help decrease the amount of plastic waste that ends up in landfills and oceans.
