If you’ve squeezed the last few drops of toothpaste out of the tube, grab some scissors and cut it open. You can use what's left to help with a myriad of household tasks. Stains on your carpet? Just rub a small amount of paste on top and scrub away with an old brush to help lift the stain and brighten the fibers. And if you have watermarks or coffee stains on the kitchen table or countertop, you can rub on some toothpaste and wipe it away to make those surfaces look as good as new.

It may seem harmless, but it’s actually illegal to take rocks out of national parks. With millions of people visiting our parks annually, if everyone took a small natural souvenir home, it would have a devastating effect on the park. If caught, not only have you committed a federal crime, but it also can result in a hefty fee. And even stacking rocks in parks is frowned upon; it disrupts the natural biodiversity and creates an eyesore. After all, the true art is what Mother Nature has already created.

During the holiday season between Thanksgiving and Christmas, it’s estimated that food waste increases by 25%, on top of the 30% to 40% of our food supply that Americans throw away on average. To reduce this, think of holiday meals as you would any meal, rather than as all-you-can-eat feasts. Encourage guests to bring take-home containers with them, or offer reusable containers for them to borrow. And think about reducing other waste by deploying reusable flatware, glasses, dishes and napkins instead of disposable.
