I just finished watching The Butterfly Effect. The movie a reference to the butterfly effect, which theorises that something seemingly innocuous, such as a butterfly's wings, may be the catalyst for something larger, such as a tornado.
Evan Treborn (Ashton Kutcher), who suffered severe traumas as a boy, copes with the pain by blacking out at moments of high stress. While searching for an answer to heal his emotional wounds, he finds that when he reads from his adolescent journals, he travels back in time, and is able to essentially "redo" parts of his past. There are consequences of his choices, however, that he then propagates back to the present; his alternate futures vary from frat boy to prisoner to amputee. As he continues to do this, he realizes that even though his intentions are good, the actions he takes always have unintended consequences. In addition, he needs to go further back in time after every attempt as several fatal mistakes he makes do something to wipe out that and all subsequent journal entries.
What we can learn from this movie is that any small thing we do in the present, might have a huge or adverse effect on us and other in the future.
