Many of us have switched from manual toothbrushes to electric ones when it comes to dental care. But when it's time to replace the toothbrush, how do you recycle it? The good news is that electric toothbrushes have an integrated rechargeable battery. And the nonprofit Call2Recycle has tens of thousands of free recycling boxes across the United States where you can drop off rechargeable batteries for recycling -- including electric toothbrushes. Just put the old toothbrush in the box, and the organization will handle the rest. Learn more at call2recycle.org.

One of the great urban myths is that birds that eat uncooked rice die because the rice expands in their stomachs. The reality is many wild birds feast on rice -- to the dismay of rice farmers -- and it is a perfectly fine carbohydrate for them to eat. But many wedding venues ban rice from being thrown into the air because of lawsuits from people slipping and falling on the grain. To keep legal eagles at bay and to offer birds a more nutritionally complete meal, toss dried millet into the air instead. It's inexpensive, a finer grade and a whole grain that all types of birds love to eat.

Perfumes, colognes and body sprays can have up to 500 toxic chemicals in them; many advise avoiding wearing fragrances on your skin altogether. But if you love fragrance, look for USDA-certified organic perfumes. These scents use food-grade ingredients to create their scents, free of harsh chemicals and artificial anything. Since organic scents are still in their infancy, you can also wear your conventional scent on your clothes only. Instead of spraying perfume on your skin, mist your clothes to envelope yourself in your favorite eau de parfume.
