Want to give your houseplants a natural boost, clean them up and make them look their best in just one step? Bring them outside the next time there's a good rainstorm. Since treated tap water can contain mineral deposits that build up over time, fresh rainwater can rinse off those hard deposits. Plus, the dust and debris on the leaves will rinse off. And since tap water can also contain chlorine, a fresh flush of clean rainwater can help them thrive. When it clears up, they'll get a strong dose of bright sunshine (which they love), and it'll dry off the excess water.

The World Health Organization estimates that over 360 million people all over the world have some form of hearing loss. Yet only 10 percent of those people actually have access to hearing aids. The Lions Club Hearing Aid Recycling Program collects used devices through recycling bins or its mail-in program and refurbishes them for those in need. It offers the hearing aids to people with limited financial resources so they can gain the gift of hearing. Learn more at lionsclubs.org.

Your old bicycle can be the perfect means of transportation for a person in need halfway around the world. The nonprofit Bicycles for Humanity collects used and even broken bikes, and repairs, recycles and distributes them. It fills shipping containers with used bikes and unloads them in developing countries. Then the container becomes the "bike shop" -- it's filled with tools and parts, too -- where the bikes are repaired on the spot. To donate, just visit bicycles-for-humanity.org.
