Common kitchen scraps that are birds' favorite delights are eggshells. In the spring and summer months, female birds crave the calcium that comes from eggshells, since their body has been drained of calcium from laying eggs. To prepare eggshells for birds, rinse them and bake them on a cookie sheet at 250 degrees until they are dry, which sterilizes them. Place the eggshells near a feeder or on a flat surface, and watch birds of all sorts gobble them up.

Got a dead houseplant? There's no need to toss it into the trash, where it won't have a chance to biodegrade in the landfill. In fact, even though it's dead, it can help create healthy soil in your yard or garden. Remove the dead plant and shake off the excess potting soil. Use a lawnmower to pulverize it into smaller pieces. The organic matter can be added to a compost bin or sprinkled on the yard, where it will naturally decompose in no time.
