Just because you don’t want to reuse something doesn’t mean somebody else wouldn’t want to. Some people have yard sales to get rid of things they don’t want anymore. Ask your students to tell you about their experiences with family garage sales. If they haven’t had one, suggest that they help their parents put one on. They could be making money and saving the Earth! If a yard sale isn’t your cup tea, thrift stores, secondhand stores, and antique stores all sell used items.
There also organizations that accept donations of used items for people in need. For example, homeless shelters are often looking for people to donate clothing, coats, and blankets. Some organizations help parents who don’t have very much money by collecting donations of baby blankets, clothing, toys, cribs, and strollers.
