Another option for symbolic adoptions - some of my favorite places by my favorite environmental organization - the Sierra Club:

Give a Gift That's Truly Wild! Now you can give a green holiday gift and at the same time help protect the Arctic National Wildlife Refuge, Yosemite, or another spectacular wild place. A Sierra Club Wild Places sponsorship is a special gift that also helps preserve America's wild legacy.
Sponsorship gifts cost as little as $25 and include a plush puppet and/or rucksack that will delight fledgling environmentalists as well as the grownup tree-huggers in your family -- and shipping is FREE! By giving a symbolic sponsorship gift, you can affirm your environmental values, while sharing those values with a family member or friend in a way they are sure to enjoy.

Dump Your E-Hog Xmas lights

If you, like me, have a bag of old fashioned Christmas lights (my C-7, C-9, and even icicle lights are HISTORY) that you just can't bring yourself to throw away, here is your chance. HolidayLEDs.com will recycle them for you for free, you just have to pay postage. They have to be postmarked by January 31, but you can send them parcel post, so that may not cost you too much. Or, take them apart yourself, I hear that the scrap metal market is way hot right now. But do NOT give them to Goodwill, because someone will use them as Christmas lights (duh) thus negating any positive benefit you hoped to achieve by replacing your guzzly bulbs in the first place.

Oh, and also, a tip for next year- Greg disliked the cold, bluish lights our LEDs gave off, so I used squares of red and white tissue paper on top and secured them with the tiny rubber bands used for girls' braids (the Goody area of your drug store will have them) which made the light far more pleasant. It only took me about an hour and a half to do 150 lights. The packaging said not to cover the bulbs, but they burn so cool that with supervision I think the risk is minimal.
