We have tried to make our game as Earth-friendly as possible. All the paper is recyclable. The ink is vegetable oil-based ink. The game pieces are either made by nature or completely recyclable. Our goal in making this game was to have as little impact as possible on the planet and at the same time create a game that shares helpful information. And of course we wanted to make the game fun! But at some point if you’ve had enough fun with your game, please either pass it on to a friend or just deposit the parts in the appropriate recycling bin and let your game become something new!
