It's easy to send an e-card to celebrate someone's birthday, and you know it'll get to the recipient, wherever they are in the world. If you're going to send a digital greeting card, why not send one that helps preserve threatened lands? The Nature Conservancy has an e-card program that lets you pick a beautiful scenic card, a personalized message and make a donation to the nonprofit in any amount you want. Your card will give back to important conservation work in a few easy steps. Your donation is tax-deductible, too. Choose from scenic landscapes, wildlife images and more. Learn more at nature.org.
