Looking for a good Earth Day activity?

Head to Facebook to play Ecotopia, a game designed by Talkie in collaboration with actor Harrison Ford and Arlington, Va.-based environmental group Conservation International.

Careful, though, you might just learn something.

In Ecotopia, players start off in an unsustainable city, then gather resources to clean it up. According to the release, players will also be able to see friends’ maps to collaborate.

More than an earth-themed Farmville, the game will also let players share their real-world environmentally friendly actions to earn points in the game.

In a statement, Chris Swain, founder and CEO of Talkie, said, “Ecotopia harnesses the power of social media by providing an entertaining play experience and also inspiring players to make a positive difference in the world.”

Ford, the Vice Chairman of Conservation International, said in the release: “This game represents a refreshing new way to engage millions of people in addressing critical environmental issues and finding solutions that work for the well-being of humanity.”

The game is launching in open beta today, in honor of Earth Day.
