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.

Do you have old clubs, balls, apparel, bags, range finders or other equipment related to golf gathering dust in the garage? It's time to put them to good use and support the nonprofit The First Tee. Started in 1997, the charity uses golf to instill values in young people through interactive after-school programs. And the charity makes it easy to donate: Just visit thefirsttee.org and enter your donation summary on the site. The organization provides a free shipping label. Once it receives the items, you'll get a receipt you can use for tax-deduction purposes.

Hummingbirds may be among the most beautiful and unusual bird species in the world, but they are also vulnerable to extinction. To help protect them, avoid using insecticides outside the home. Hummingbirds get their nutrition from nectar, so any trace chemicals can make them sick. Added bonus: They eat insects to get their protein, which keeps the insect population in check naturally.
