Every action has a consequence. No matter what this action is, from having another piece of cake to stealing a CD, it will have some kind of an effect. The action could have a small effect, like getting a stomachache from eating too much cake. It could have an extremely large effect, like parents needing to pay a bail they couldn’t afford because their child was caught stealing. Also, a small thing could end up having a huge effect. For example, if a student decided to not take a certain class in high school, it may not be such a big deal. But, once that student decided upon a major in college, it could turn out that he needed to have taken that particular class because that major’s foundation was taught in that class. This would mean that the student might have to major in another area in which they weren’t really interested. The student might end up hating his life and living in a state of depression. This is a hypothetical example of the butterfly effect, which states that when a single butterfly flaps its wings, it could cause a tornado halfway around the world. Although these examples are negative ones, there are also positive sides to the butterfly effect. Let’s say that someone is walking down the street in a city and they are approached by someone collecting money for finding a cure to cancer. The person might donate five dollars. That person’s five dollar donation could be the exact amount used to purchase a material that leads to the creation of a cancer vaccination. What goes around comes around because every action has a reaction.
