I found this fantastic little eco-friendly jewelry business a little while back called
Figs and Ginger. Right now they are doing a really fantastic promotion to encourage everyone to plat a tree, and I thought I'd give it a little plug here :)
You can watch this video on www.livejournal.com
Earth Day Giveaway from Figs & Ginger! from
Figs & Ginger on
Vimeo.
Basically, if you plant a tree and send in proof, you not only are doing something great for the planet, you can also receive some fantastic free jewelry! The first 50 get a Limited Edition Tree necklace plus either a set of fawn earrings or a fawn tie tack. Then the next 300 can choose between a fawn earring set or a fawn tie tack.
In other words, its a fantastic situation all round, and helps out the enviroment. Perhaps you'll find you enjoy gardening too!
