Want to do something green? Why not play a video game or watch a movie? Sony will donate $1 to Conservation International
for each "unique paid transaction" made on the PlayStation Store on Earth Day (April 22), with a maximum contribution of $10,000. Each purchase must be made from the PlayStation Video Store.
The PlayStation Store currently features a "Save Our Earth" section featuring a rather eclectic mix of sort-of-Earth-related games, including PixelJunk Eden
and er, Burn Zombie Burn
