No matter how you look at it, paper towels create waste. During your next trip to the grocery store, buy some reusable microfiber towels, which grip dirt and dust like a magnet, even when they get wet. When you are finished with them, toss the towels in the wash and reuse them again and again. They are even great for countertops and mirrors. When you absolutely have to use disposable towels, look for recycled products. If every household in the United States replaced just one roll of virgin fiber paper towels (70 sheets) with 100 percent recycled ones, we could save 544,000 trees.
