Draw a picture showing people divided into three groups. Draw a large-scale picture, taking perspective into account. People in the first group are diligently planting small trees one by one in the ground, people in the second group are supervising the first group by telling them the direction to plant the trees, and people in the third group are people in the second group. While watching, you will be thinking about the direction of the forest as you look at the forest made up of the trees planted like that.
