If you're visiting Florida when millions of freshly hatched sea turtles are making their way to the ocean, you can do just one thing to help them out: Turn off the lights. The baby turtles make their way to water at night using the light of the moon to guide the way. But when outdoor lights (or even bright lights coming from inside homes) are brighter than the moon, they often head toward those light sources. And when they go the wrong direction, it can lead to their demise. Turn off the lights and spread the word if you find yourself in Florida anytime June through November.

More than 20 billion paper catalogs are mailed every year in the United States; many go unread and unrecycled, straight from the mailbox to the trash can to the landfill. The easiest way to stop this is to unsubscribe and get your name off mailing lists. But what do you do if you actually want to browse through catalogs? Good news: Most retailers are now offering free downloadable versions of their catalogs to smart tablet devices like the iPad. You can subscribe just like a magazine; when new ones are available, they're automatically updated and ready to browse.

When you snack on pistachios, you're left with a pile of shells that typically gets tossed in the trash. But don't throw those shells away! Pistachio shells are slow-burners that make a perfect fire starter for the backyard grill or fire pit. You can also line the bottom of pots with unsalted shells to help give houseplants good drainage. Salted shells can be placed around the base of plants that are often attacked by slugs; the salty coating will deter slugs from climbing up on the plant. And finally, if you have orchids, mix shells with your orchid potting mix to give the right airy medium to help the exotic flowers thrive.
