Threadless.com is at it again!  Last year, for Earth Day, they donated a dollar of each sale to PlantaBillion.org, and this year they’re at it again.

All week, Threadless is offering up its “nature tees” at $12 a pop, and donating $1 from every single order to PlantaBillion.org. There’s a damned fine selection of nature-inspired tees, too – over 45 of them!  My favorites, as per usual, are below.
