In this book you will learn how to prevent soil erosion by playing a game. The players must imagine that they are conservationists, dedicated to saving Zimbabwe's soil from being washed away. At each step in the game a player can either lose soil or gain soil in the form of points. The points are added or subtracted to give your score. The player who ends the game with the highest score has saved the most soil and has won the game.
