If you need the perfect gift for someone who's hard to shop for - or for the person who cares about the Earth - then you've luckily got a lot of options. The folks at Oceana have a program where you can adopt an octopus, a dolphin, or even a shark (you'll get a cute cookie cutter or stuffed animal with your gift). Or, The Nature Conservancy makes it easy to adopt an acre somewhere in the world (like the rainforest). And, MyEcoFarmer.com has apple trees that you can adopt. Instead of giving stuff, help someone adopt a cause this year.
