Does your office use Keurig K-Cups to brew fresh coffee one cup at a time? While they are convenient, they are also ecological disasters, since they are difficult to recycle and are wasteful. If you can't convince others to give up their K-Cup addiction, try the next best thing: Recycle them. The new Grounds to Grow On program is a mail-in recycling box that you can fill up with used K-Cups. The recycling company separates the used grinds for compost, and the other materials are used to generate energy with almost no landfill waste. Learn more at groundstogrowon.com.

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.
