The childhood story that I used was one of my favorites, "The Lorax"
What happens in this story is a man goes to a place with beautiful trees and animals, but he does not appreciate them farther than what they can do for him. He cuts down a tree and makes "thneed", a "revolutionary" invention that can do anything. A magical creature called the Lorax, who speaks for the trees, tells him that he needs to stop making thneeds because he is hurting others, even though he is helping himself. During the story his business harms the environment to the point were all the animals have to leave, but he decides to keep on working. Eventually he uses up all of the trees and is no longer able to make thneeds, so his entire business falls apart, leaving him alone and unloved.
I think that the implication of this story are that we can't expect everything to go our way without working for it. I understand this because the Once-ler says "UNLESS someone like you cares a whole awful lot, nothing is going to get better. It's not." What are some other things that aren't going to get better without more attention?
I also believe an implication is that we need to understand that our actions have consequences that can effect other people as well as ourselves. I understand this because even though the Once-ler's actions did not affect himself, it caused the birds, bears, and fish to have to leave their home to avoid death. What are some things in our own lives that hurt other people, but help ourselves?
